AbsolutAire Make-Up Air Units
AbsolutAire covers nearly every make-up air configuration from a single maker, direct-fired, indirect-fired, tempered, untempered, and DX-cooled. That range is why engineers spec the line, and why the right model depends on your airflow and tempering needs.
We are an authorized AbsolutAire distributor and spec the unit to your application, not the other way around. Every unit is US-made, backed by strong manufacturer warranties, and we handle any warranty issue so you are not dealing with the factory alone.

AbsolutAire Make-Up Air Product Lines
AbsolutAire builds make-up air across a wide airflow band, from low-volume kitchen units to large industrial systems. The series below cover the configurations engineers spec most, so you can match airflow and tempering before you quote.
| Series | Configuration | Heat or Cool Source | Airflow Range | Typical Application |
|---|---|---|---|---|
| V-Series | Direct gas-fired, 100% fresh air | Gas heated, optional evaporative or DX cooling | 800 to 13,000 CFM | Kitchen and food service make-up air |
| AA-Series | Direct gas-fired, draw-through | Gas, with electric, steam, or hot water options | 800 to 54,000 CFM | Warehousing, paint and spray finishing, manufacturing |
| R-Series | Heated and cooled, energy-saving | Gas, optional chilled water | 4,000 to 130,000 CFM | Large industrial and high-volume facilities |
| I-Series | Indirect gas-fired, 80% efficient | Gas, gravity or power vented | 3,000 to 130,000 CFM | Commercial and institutional spaces needing separated combustion |
| M-Series | Untempered fan box | None | 800 to 14,000 CFM | Ambient replacement air where tempering is not required |
AbsolutAire Configurations and Tempering Options
The series table covers what each line does. Tempering is the next decision, and it drives both equipment cost and operating cost over the life of the unit. AbsolutAire lets you separate the heating method from the cooling method, so you size each to the load rather than accepting a packaged compromise.
| Tempering Method | How It Works | Best Fit |
|---|---|---|
| Direct gas-fired | Burner sits in the airstream, near 100% fuel efficient, all combustion heat delivered to the space | High-volume heating where outside air is exhausted, not recirculated |
| Indirect gas-fired | Heat exchanger separates combustion gases from supply air, around 80% efficient | Spaces that cannot tolerate combustion byproducts in the airstream |
| Electric, steam, or hot water | Alternative heat sources where gas is unavailable or a plant already has steam or hot water | Facilities with existing utility infrastructure |
| Evaporative cooling | Water-saturated media cools incoming air, low energy draw | Dry climates and high-volume cooling on a budget |
| DX or chilled water cooling | Mechanical cooling for tighter temperature and humidity control | Process spaces and buildings needing conditioned make-up air |
Most engineers land on a tempering choice once they know the airflow volume and how the space handles exhaust. Tell us the application and we spec the heating and cooling combination that fits, then match it to the right AbsolutAire series.
Applications for AbsolutAire Make-Up Air
AbsolutAire units fit the same applications RWA specs every week. The right series depends on how much air the space exhausts and whether that air needs heating, cooling, or both.
| Application | What It Needs | Typical Tempering |
|---|---|---|
| Kitchen and food service | Replace hood exhaust, hold neutral pressure so doors open and burners stay lit | Direct gas-fired |
| Warehousing and distribution | Temper high exhaust volumes without overworking building heat | Direct gas-fired, large airflow |
| Paint and spray finishing | Clean, tempered supply air at controlled velocity across the booth | Heated, sometimes cooled |
| Manufacturing and process | Stable temperature year round | Heated and cooled |
| Wastewater and high-exhaust | Match replacement air to the volume leaving the building | Wide airflow range |
Sizing starts with the exhaust load. Send us the application and we match it to the right series.
Why Engineers Source AbsolutAire Through Us
AbsolutAire gives you the range. We give you the judgment on which series fits, because we carry multiple make-up air lines and spec the one your application calls for, not the one we need to move.
Our application engineers size the unit against your airflow, exhaust, and tempering load before anything gets quoted. You get the right configuration the first time.
Every unit is US-made and backed by strong manufacturer warranties.
We handle any warranty issue directly, so you are never left dealing with the factory alone. Call 847-262-3457 ext. 23 and we will spec your AbsolutAire unit to the application.
