MOAS odor abatement for commercial kitchens
Treat cooking odor before it leaves the building.
MOAS mists Odor Neutralizer Solution into your exhaust duct through two remote nozzles. A wall-mounted stainless-steel cabinet, fabricated in Colorado by a family business since 1986.

Cooking odor travels.
Kitchen exhaust can carry cooking odor to neighbors, guests and the street. MOAS treats that odor inside your exhaust duct, before the air is discharged.
- Sidewall and ground-level dischargeExhaust that leaves the building near sidewalks, patios, doors or windows.
- Shared and mixed-use buildingsKitchens below apartments, beside offices, or inside hotels and airports.
- Neighbors close byHomes and businesses within reach of the exhaust fan.

How MOAS works
A cabinet on the wall, two nozzles on the duct. Everything happens while your exhaust fan runs.

The cabinet mixes the solution
A wall-mounted stainless-steel cabinet, 24 by 32 by 8 inches deep, mixes Odor Neutralizer Solution with cold water. The container below it holds up to 10 gallons.

Two nozzles mist it into the duct
Air turns the solution into a fine mist. Nozzles mounted outside the exhaust duct direct it into the exhaust stream.

Odor is treated before the air leaves
The exhaust carries the mist toward the fan, neutralizing cooking odor in the exhaust stream before the air is discharged.

Compact, listed and easy to own.
- Stays outside the duct
Only the two nozzles meet the exhaust. The cabinet hangs on a wall in any convenient, ventilated spot near your kitchen staff.
- ETL Listed
For the United States and Canada, under Intertek Report 101453585DEN-002 (UL 197 and CSA C22.2 No. 109).
- Up to 6,000 CFM per system*
Each two-nozzle system covers exhaust up to 6,000 CFM. Configuration is set for your project.
- Works with your exhaust fan
An exhaust-fan interlock powers MOAS when the fan runs, and its SmartRelay can limit operation to cooking hours.
- Tells you when it’s low
When the solution runs low, a buzzer sounds and the red light on top of the cabinet comes on.
- Simple monthly care
Trained kitchen staff press each nozzle’s cleaning button, test the low-solution alarm and check the air filter once a month.
*Performance varies with cooking process, hood grease-removal performance, exhaust configuration, installation, dwell time and calibration. Results are not guaranteed. Capacity is subject to project-specific configuration; smoke reduction is not a particle-filtration rating.
EPFA dry filtration
Need smoke and grease filtration too?
The Enviro-Pak Filter Assembly (EPFA) is Molitron’s pollution control unit for light-duty commercial kitchen exhaust. Three dry filter stages remove smoke particulate and grease vapor, with no water, pumps or chemical dosing.
- UL Listed
- Models EPFA‑24 through EPFA‑144
- 1,800–10,800 CFM
- Eleven models
- MERV 14 final stage
- Or an optional carbon stage
Some projects use both: EPFA filters the exhaust and MOAS treats the odor. Molitron reviews the combination with you.

Questions owners ask
Planning details, upkeep and listings. For anything specific to your kitchen, ask us directly.
Where does the MOAS cabinet go?
In any convenient, ventilated spot near your kitchen staff, where they can reach the solution container and hear its alarm. It doesn’t need to sit beside the cooking line, and it stays outside the duct.
What does MOAS need from the building?
A dedicated 120 VAC, 20 A circuit run to the MOAS exhaust-fan interlock, and a ¼-inch cold-water supply (80 PSI maximum) through a shutoff valve. Routing is set for each project.
How much odor does MOAS remove?
Up to 95% odor reduction and up to 50% smoke reduction, depending on operating conditions. Results vary with the cooking process, hood grease-removal performance, exhaust configuration, installation, dwell time and calibration, and are not guaranteed.
What upkeep does it take?
Once a month, with MOAS and the exhaust fan running, trained staff press each nozzle’s cleaning button several times, test the low-solution alarm and check the air compressor’s intake filter. Refill the solution container when the buzzer sounds.
Is MOAS listed?
Yes. MOAS is ETL Listed for the United States and Canada under Intertek Report 101453585DEN-002, to UL 197 and CSA C22.2 No. 109. A listing is not a code approval for a particular project; your local authority makes that decision.
Does EPFA control odor too?
EPFA’s standard stages filter smoke particulate and grease vapor; standard filtration isn’t comprehensive odor removal. For odor, EPFA offers an optional carbon final stage for a project-specific objective, or you can pair it with MOAS.
Who installs and services MOAS?
Authorized personnel or trained kitchen staff handle startup and service. For maintenance or repair, they open the cabinet door to reach the components directly.
How quickly will we hear back?
We reply the same business day, and within one business day at most.
