Essential Restoration Equipment for Water and Fire Damage

Water and fire damage can disrupt homes, commercial buildings, warehouses, and industrial facilities across the United States. From burst pipes and basement flooding to hurricane-related water intrusion and structural fires, property damage often requires a coordinated response involving water extraction, structural drying, air filtration, and specialized cleaning.

For professional restoration contractors, having the right water and fire damage restoration equipment is essential for reducing secondary damage, protecting indoor environments, and returning affected properties to a suitable condition for repair and reoccupation.

A professional restoration equipment setup often includes low-grain refrigerant (LGR) dehumidifiers, high-velocity air movers, and air scrubbers. Each machine performs a different function, and the equipment must be selected according to the type and extent of damage.

PREAIR offers a restoration equipment lineup that includes LGR85, LGR105, and LGR155 dehumidifiers, the PA-LO-U1000 air mover, and the AF650 air scrubber. Together, these products can support key stages of water damage mitigation and selected post-fire restoration tasks when configured for the specific job requirements.

This guide explains the water and fire damage restoration process in America, the essential equipment used at each stage, and how restoration professionals can evaluate an appropriate equipment combination.

 

1. Understanding Water and Fire Damage Restoration in the United States

Water and fire damage restoration involves more than cleaning visible damage. Moisture can migrate into wall cavities, subfloors, insulation, and other building assemblies, while fire residues and smoke can contaminate surfaces, contents, and HVAC systems beyond the area directly affected by flames.

In the US restoration industry, two important reference documents are the ANSI/IICRC S500 Standard for Professional Water Damage Restoration and the ANSI/IICRC S700 Standard for Professional Fire and Smoke Damage Restoration.

S500 guides assessing and restoring water-damaged buildings and contents. S700 addresses fire and smoke residue assessment, cleaning, odor management, and related restoration procedures.

Professional contractors should consult the applicable standards, building requirements, and safety guidance when developing a restoration work plan.

Water damage restoration

Water damage can result from:

Burst or leaking plumbing pipes.

Appliance and water heater failures.

Roof leaks and storm damage.

Hurricanes, flash floods, and severe weather.

Basement and crawl space flooding.

Commercial building leaks and sprinkler-system discharges.

The restoration process typically involves identifying the water source, assessing contamination and damage, extracting standing water, removing or cleaning unsalvageable materials, and drying affected structures to documented goals.

Fire and smoke damage restoration

Fire damage can involve several types of loss:

Direct flame and heat damage to building materials.

Soot and smoke residue on walls, ceilings, furnishings, and equipment.

Persistent smoke odors in porous materials.

Water damage from firefighting activities and sprinkler systems.

Contamination of HVAC systems and air conveyance components.

Fire restoration therefore requires a combination of source removal, specialized cleaning, air filtration where appropriate, odor management, and moisture control when water has entered the building.

A key distinction is that water damage restoration primarily focuses on contamination assessment, water removal, and controlled drying, while fire damage restoration also requires specialized removal of combustion residues and management of smoke-related contamination.

 

2. The Water Damage Restoration Process: From Emergency Response to Structural Drying

A successful water damage restoration project follows a structured workflow. Equipment selection should support each stage rather than relying on a single machine to solve every problem.

Step 1: Emergency assessment and damage documentation

Restoration technicians first assess the affected property and determine whether it is safe to enter. Electrical hazards, structural instability, sewage contamination, and other risks must be addressed before restoration work begins.

The team then identifies the source of water intrusion, documents visible damage, measures moisture levels, and evaluates affected building materials.

Common equipment includes:

Moisture meters.

Thermal imaging cameras used as a supplementary inspection tool.

Hygrometers and temperature sensors.

Inspection tools and documentation systems.

Appropriate personal protective equipment.

Thermal imaging can help identify areas that warrant further investigation, but it does not directly measure moisture content. Moisture readings and other appropriate verification methods remain important.

Step 2: Water extraction and removal of unsalvageable materials

Standing water should be removed as soon as it is safe and practical. Delayed mitigation can allow moisture to penetrate further into porous materials, increasing drying time and the potential for secondary damage.

Common equipment includes:

Submersible pumps for suitable standing-water conditions.

Wet vacuums and extraction equipment.

Truck-mounted or portable extraction systems.

Hand tools for removing damaged materials where necessary.

Dehumidifiers and air movers are generally used after bulk water removal has been addressed. They support the subsequent drying process rather than replacing the need for effective extraction.

The appropriate remediation sequence also depends on water contamination. Contaminated materials may require specialized handling, cleaning, removal, or remediation before restorative drying proceeds.

Step 3: Structural drying with air movers and LGR dehumidifiers

Structural drying is a critical stage of professional water damage restoration.

Water absorbed by drywall, wood framing, concrete, flooring, and other porous materials must be removed or allowed to evaporate under controlled conditions. Simply drying the visible surface does not establish that the material beneath it is dry.

Two types of equipment work together during this stage: air movers and dehumidifiers.

Air movers create directed airflow across wet surfaces, supporting evaporation and helping release moisture from affected materials.

LGR dehumidifiers remove water vapor from the air, helping maintain the conditions needed for continued evaporation. By reducing humidity in the drying environment, they support the transfer of moisture from wet materials into the surrounding air.

The combination can be particularly valuable in enclosed or partially enclosed drying areas where outdoor ventilation alone would be insufficient or introduce additional humidity.

PREAIR LGR85, LGR105, and LGR155 dehumidifiers can be evaluated for restoration projects requiring different levels of moisture-removal capacity. The correct model depends on the affected area, moisture load, temperature, and verified equipment performance.

Step 4: Air filtration and environmental control

Air filtration may be necessary when restoration work generates airborne dust, particulates, or other contaminants.

An appropriately selected air scrubber can draw air through its filtration system and return filtered air to the work area. When equipped and operated with suitable filters, it can help reduce airborne particulate concentrations.

For projects involving mold remediation, contaminated demolition, or other activities with specific exposure risks, contractors should follow applicable containment, filtration, and worker-protection procedures.

Air filtration is not a substitute for removing the contamination source. Similarly, a standard particulate filter does not automatically remove gases or all smoke odors; those applications may require appropriate gas-phase filtration or additional treatment methods.

Step 5: Verify drying and complete restoration

The drying process should continue until the project-specific drying goals are achieved and documented.

Technicians should monitor moisture levels in affected materials, record environmental conditions, and adjust equipment placement or operation when drying progress slows.

Once mitigation and drying requirements are satisfied, the project can proceed to appropriate repairs, reconstruction, and final evaluation.

The key principle is simple: extract bulk water, facilitate evaporation, remove moisture from the air, and verify the condition of the affected materials before closing out the drying phase.

 

3. Essential Equipment for Water Damage Restoration

A professional restoration contractor needs equipment that can address different moisture loads, building configurations, and project sizes.

LGR dehumidifiers: Remove moisture from the drying environment

Low-grain refrigerant dehumidifiers are widely used in professional restoration because they are designed for high moisture-removal demands under suitable operating conditions.

An LGR dehumidifier cools incoming air to condense water vapor, then reheats the processed air before returning it to the space. The resulting reduction in humidity helps create conditions that support drying of wet building materials.

Potential applications include:

Flooded basements and ground-floor rooms.

Water-damaged residential properties.

Commercial buildings affected by plumbing failures.

Restoration projects involving wet wood framing and flooring.

Drying operations following water intrusion caused by storms.

For contractors evaluating equipment, rated capacity should not be the only selection criterion. Performance at the expected temperature and humidity, airflow, drainage arrangement, portability, and service requirements also matter.

PREAIR LGR85, LGR105, and LGR155 restoration dehumidifiers

PREAIR offers three LGR models for restoration equipment buyers to evaluate.

PREAIR LGR85: Consider for restoration jobs where the selected unit's verified capacity matches the moisture load and drying environment.

PREAIR LGR105: Evaluate for projects requiring a different balance of capacity, operating conditions, and equipment deployment.

PREAIR LGR155: Assess for applications with greater moisture-removal demands, subject to its rated performance and the project's drying conditions.

These models provide options for contractors assembling equipment inventories for different job types. The number of machines required should be determined from the actual moisture load, building conditions, and expected drying performance—not the model number alone.

Air movers: Accelerate evaporation from wet surfaces

Air movers play a different role from dehumidifiers. They circulate air across wet surfaces to encourage moisture to evaporate from building materials.

Without sufficient air movement, moisture can remain trapped near wet surfaces, slowing the drying process. Strategically positioned air movers help distribute airflow across affected areas and can improve the effectiveness of a properly designed drying setup.

Air movers are commonly used for:

Carpet and flooring drying where materials are suitable for restoration.

Wall and ceiling drying after appropriate assessment.

Water-damaged wood and structural assemblies.

Targeted drying in residential and commercial properties.

PREAIR PA-LO-U1000 air mover

The PREAIR PA-LO-U1000 air mover can be considered part of a professional water damage restoration equipment package.

When selecting an air mover, contractors should assess its airflow characteristics, placement options, electrical requirements, and suitability for the drying environment.

Effective deployment matters as much as the number of machines. Air movers should be positioned to support evaporation and circulation without spreading contaminants into unaffected areas.

For contaminated water losses or remediation work, airflow direction and intensity must be managed according to the work plan and applicable safety procedures.

Air scrubbers: Help manage airborne particulate contamination

Water damage projects may involve demolition dust, while fire damage projects can generate soot and other fine particles. An air scrubber equipped with suitable filtration can help control airborne contaminants during appropriate restoration activities.

Air scrubbers are particularly useful when contractors need to manage air quality within a defined work area. Depending on the project, they may operate with containment and negative-pressure arrangements to help limit the migration of contaminants into adjacent spaces.

PREAIR AF650 air scrubber

The PREAIR AF650 air scrubber can be evaluated for restoration jobs requiring supplemental air filtration.

Before deployment, confirm the unit's verified airflow, filter configuration, filtration efficiency, pressure characteristics, and suitability for the specific contaminants being addressed.

For fire and smoke restoration, a particulate air scrubber may help capture airborne soot and dust, but it should not be assumed to remove every smoke odor or gaseous contaminant. Additional source removal, surface cleaning, HVAC assessment, and suitable odor-management methods may be required.

 

4. The Fire Damage Restoration Process: What Equipment Do Contractors Need?

Fire restoration presents a more complex challenge than drying alone. A property can experience direct fire damage, smoke contamination, soot deposition, and water intrusion from firefighting activities at the same time.

The restoration plan must address these different conditions in the correct sequence.

Step 1: Confirm safety and assess the extent of damage

Before restoration begins, the property must be cleared for safe access by the appropriate authorities or qualified professionals.

Technicians assess structural conditions, fire residues, smoke migration, affected contents, and possible HVAC contamination. The scope should distinguish materials that can be restored from those that require removal or replacement.

Where hazardous building materials or unusual combustion residues are suspected, qualified specialists should assess the associated risks.

Step 2: Secure the building and prevent further damage

Fire-damaged buildings may have broken windows, compromised roofs, or openings that allow rain and outdoor moisture to enter.

Depending on the situation, mitigation may include temporary roof protection, board-up services, and water extraction. Any necessary stabilization should be performed by qualified personnel.

If water from firefighting has entered the structure, the project may require both fire residue remediation and water damage restoration procedures.

Step 3: Remove soot and clean affected surfaces

Soot removal requires methods appropriate to the residue, surface, and degree of contamination.

Dry particulate removal, specialized cleaning agents, controlled wet cleaning, and other methods may be used depending on the materials and conditions.

The sequence matters. Applying the wrong cleaning method too early can smear residues or drive contaminants deeper into porous surfaces.

Air scrubbers can support airborne particulate control during suitable cleaning and remediation operations, but they do not replace direct removal of soot from surfaces.

Step 4: Manage smoke contamination and indoor air quality

Smoke can migrate beyond the room where a fire originated, affecting adjoining rooms, contents, ductwork, and other building systems.

A professional fire restoration plan may require:

HEPA or otherwise appropriately rated particulate filtration.

Containment and pressure control where necessary.

HVAC inspection and cleaning when indicated.

Specialized odor-management procedures.

Appropriate personal protective equipment.

The correct equipment depends on the type of residue and the contaminants present. Particulate filtration and gas-phase odor control serve different functions and should not be treated as interchangeable.

Step 5: Address water damage and dry affected materials

After the necessary assessment, contamination control, and cleaning steps, wet structural materials may require controlled drying.

Water from firefighting can carry fire residues into materials and contents. Restoration teams should therefore assess contamination before deciding whether materials can be dried in place or require remediation or removal.

Where controlled drying is appropriate, LGR dehumidifiers and air movers can help remove residual moisture from affected building assemblies.

PREAIR LGR85, LGR105, and LGR155 dehumidifiers may be evaluated for these drying tasks. The PA-LO-U1000 air mover can support evaporation, while the AF650 air scrubber can assist with particulate filtration when its specifications and filtration configuration are suitable.

Step 6: Verify conditions and proceed with repairs

Before reconstruction, the restoration team should document that applicable cleaning, contamination-control, and drying goals have been achieved.

Depending on the loss, this may include moisture readings, post-cleaning inspections, HVAC evaluations, and other project-specific verification.

The objective is to establish that the affected building is ready for the next stage of restoration—not simply that visible soot or surface moisture has disappeared.

 

5. How to Combine LGR Dehumidifiers, Air Movers, and Air Scrubbers

The three equipment categories perform complementary functions. Understanding their roles helps restoration contractors create a more effective equipment plan.

Equipment	Primary function	Typical restoration role
PREAIR LGR85 / LGR105 / LGR155	Remove water vapor from the air	Controlled structural drying
PREAIR PA-LO-U1000 air mover	Increase airflow across wet surfaces	Support evaporation and drying
PREAIR AF650 air scrubber	Filter airborne particles when appropriately equipped	Supplemental particulate control

Example 1: Residential basement flooding

A basement experiences water intrusion after heavy rainfall. Once the source is controlled and standing water is extracted, technicians assess affected flooring, drywall, framing, and contents.

An appropriately sized PREAIR LGR dehumidifier can help lower the humidity of the drying environment. PA-LO-U1000 air movers can be positioned to support evaporation from suitable wet surfaces. If demolition or other work generates airborne dust, an appropriately configured AF650 air scrubber may provide additional particulate control.

The restoration team then monitors moisture levels and adjusts the setup until the specified drying goals are met.

Example 2: Commercial building water damage

A commercial property experiences a plumbing failure that affects multiple rooms and corridors.

The contractor assesses the water category, affected materials, and moisture migration before developing the drying plan. Multiple dehumidifiers and air movers may be required, with equipment distributed according to the building layout and moisture load.

An air scrubber may be appropriate if the work generates airborne contaminants or requires additional air-quality controls. The final setup should be based on the actual site conditions rather than a fixed equipment ratio.

Example 3: Post-fire restoration with firefighting water

A small commercial building suffers fire and smoke damage, and firefighting water penetrates the flooring and lower walls.

The restoration contractor first addresses safety, documents the damage, and establishes a plan for soot removal and contamination control. Surfaces and contents are cleaned using appropriate methods, and affected HVAC systems are evaluated.

Once the water-damaged materials have been assessed and the required remediation has been completed, PREAIR LGR dehumidifiers and PA-LO-U1000 air movers can be considered for structural drying. The AF650 air scrubber may support particulate control when suitably configured for the work.

This combined approach addresses moisture and airborne particulate concerns without confusing drying equipment with fire residue cleaning equipment.

 

6. How to Select the Right Restoration Equipment Package

Restoration contractors should consider the following factors before purchasing equipment or preparing a project-specific equipment list.

Moisture-removal capacity

Select dehumidifiers based on the expected moisture load and operating conditions. Compare rated performance at relevant temperature and RH conditions rather than assuming that the highest nominal capacity will always produce the best results.

Airflow and drying layout

Consider the area and materials to be dried, the location of wet surfaces, and the airflow requirements of each zone. Air movers should complement the dehumidifier layout rather than simply being distributed evenly across a room.

Filtration requirements

Identify the type of airborne contaminant and choose suitable filtration. A filter designed for particulate removal may not be sufficient for smoke gases or odors.

Portability and deployment

Restoration contractors often move equipment between residential and commercial sites. Evaluate the dimensions, weight, handles, wheels, drainage, electrical requirements, and transportation needs of each unit.

Monitoring and documentation

Equipment performance should be evaluated alongside moisture readings and environmental measurements. Daily documentation helps technicians identify drying delays, adjust equipment, and demonstrate that project goals have been met.

Maintenance and serviceability

Filters, coils, drainage components, electrical systems, and other service items should be accessible for routine inspection and maintenance. Reliable operation is especially important when restoration equipment must run for extended periods.

8. Frequently Asked Questions About Water and Fire Damage Restoration Equipment

What equipment is needed for water damage restoration?

Common equipment includes water extraction systems, LGR dehumidifiers, air movers, moisture meters, temperature and RH instruments, and appropriate protective equipment. Air scrubbers may also be required for certain jobs involving airborne contaminants.

What is an LGR dehumidifier used for in restoration?

An LGR dehumidifier removes moisture from the air to support controlled drying of water-damaged building materials. It is commonly used with air movers and moisture-monitoring equipment during professional structural drying.

Can the same equipment be used for water and fire damage restoration?

Some equipment can support both types of projects. LGR dehumidifiers and air movers may be useful when fire suppression water has damaged building materials. Air scrubbers can support particulate control during suitable cleaning operations. However, fire restoration also requires specialized soot removal, residue cleaning, and smoke odor management.

Does an air scrubber remove smoke odors?

Not necessarily. A particulate air scrubber can capture airborne particles when equipped with suitable filters, but removing gases and odors may require gas-phase filtration or other specialized methods. Always confirm the filtration configuration and its suitability for the contaminants involved.

How long does water damage restoration take?

The duration depends on the amount of water, contamination category, materials affected, building conditions, and drying goals. Some projects may achieve structural drying within several days, while extensive or complicated losses can take considerably longer.
