Industrial Air Handling Unit (AHU) Built to Spec
Industrial air handlers carry the ventilation load standard HVAC equipment can’t touch. Set air changes per hour, tempered air across open floor plates, filtration for process particulate.
The AHU has to match the application. The lead time has to match your schedule.
We spec and supply industrial air handling units from multiple manufacturer lines. When one manufacturer’s lead time blows your timeline, we pivot to an equivalent unit from another line.
Your spec stays intact. Your schedule holds.

Key Takeaways
Industrial Air Handling Units We Supply
Every unit below comes configured to your application. Housing construction, mounting location, airflow, and controls are spec decisions, not catalog limitations.
| Unit Type | Configuration Options |
|---|---|
| Custom air handlers | Single or double wall housing, indoor or rooftop, CFM sized to spec |
| Air turnover units | Large volume tempered air with minimal ductwork |
| Filtered ventilation units | MERV rated filter banks, carbon modules for odor and particulate |
| Explosion proof air handlers | Class I Div 1 and Div 2 construction, NEMA 7 controls |
| Make-up air units | Direct fired and indirect fired, 100% outside air |
| Door heaters | Truck door and loading dock positions for cold weather months |
What an Industrial Air Handler Does
An industrial air handler circulates, conditions, and filters air across large facilities. One unit handles four jobs that packaged HVAC equipment splits across separate systems.
- Ventilation. Delivers set air changes per hour with outside air to control indoor air quality.
- Filtration. Captures dust and process particulate through MERV rated filter banks.
- Temperature control. Heats and cools through coil packages matched to your load.
- Pressure control. Works alongside exhaust systems to keep building pressure where you set it.
Units mount indoors, outdoors, on grade, or on the roof. Construction runs from bolt-together to all-welded housings.
Air Handler vs Make-Up Air Unit
The difference comes down to recirculation. An air handler conditions a mix of return air and outside air, then sends it back through the facility. A make-up air unit delivers 100% outside air to replace what your exhaust systems remove.
| Â | Industrial Air Handler | Make-Up Air Unit |
|---|---|---|
| Air source | Return air mixed with outside air | 100% outside air |
| Primary job | Circulate, condition, and filter facility air | Replace exhausted air, hold building pressure |
| Where it fits | Air changes, tempering, filtration | Facilities with source capture or pollution control exhaust |
Running heavy exhaust off a dust collector or paint line? You likely need a make-up air unit instead. Many facilities run both.
Where Industrial AHU Earn Their Keep
The same unit type does different work depending on the building. Three applications cover most of what we quote.
Warehouse Air Handlers That Cover the Whole Floor
Open floor plates need tempered air without miles of ductwork. Air turnover units pull air from floor level, condition it, and discharge across the space. Pair them with unit heaters at spot-load areas and the whole footprint stays workable through both seasons.
Manufacturing Plants Running Dust, Fume, or Finishing Lines
Where source capture can’t reach every contaminant, air handlers supply outside air to dilute what’s left. Filter banks and carbon modules handle particulate and odor. Paint and finishing rooms run dedicated units sized to the booth exhaust, often paired with utility set fans.
Plant Offices the Main System Can’t Reach
Interior offices, control rooms, and break areas inside a production building need their own conditioned air. Compact air handlers with electric duct heaters handle isolated spaces without tying into the plant system.
Explosion Proof Air Handlers for Classified Areas
Refineries, drilling sites, and wastewater plants can’t run standard equipment in classified space. Every component in the airstream and the electrical path has to match the area classification.
We build explosion proof air handler specs around these requirements:
- Spark resistant construction per AMCA 99, matched to Class I Div 1 or Div 2.
- UL listed motors rated for your class, division, and group.
- NEMA 7 enclosures on control panels and junctions.
- Temperature codes held below the ignition point of surrounding gases.
- NFPA 496 pressurization packages where declassifying the space beats rating every component.
We supply the full classified-area package alongside the unit, from explosion proof heaters to explosion proof actuators. Our team reviews area classification drawings before quoting oil and gas HVAC equipment.
