MOAS Product Brochure · Version 2.0, October 2026
Cooking odor, treated inside the exhaust.
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. The Molitron Odor Abatement System (MOAS) mixes Molitron Odor Neutralizer Solution with your building’s cold water and sends it, with compressed air, to two nozzles that mist it into your exhaust duct.

*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.
01
From cold water to a fine mist.
Everything that mixes and meters the solution is in one stainless steel cabinet. Follow the water, the solution and the air through it, step by step.
- Cold water
- Odor Neutralizer Solution
- Diluted solution
- Compressed air

02
Runs itself, and tells you when it’s low.
- Runs on your schedule. Cooking periods are set in the IDEC SmartRelay so MOAS runs during those times. The exhaust-fan interlock prevents operation whenever the fan is off.
- Warns before it runs dry. The low-solution alarm monitors the container through a pressure-sensing tube. When solution runs low, the cabinet buzzer sounds and the red light on top illuminates until the container is refilled.
03
A cabinet on the wall, two nozzles on the duct.
The cabinet and its solution container go on a wall; only the two misting nozzles go in your duct. Plan the air and solution lines between them for convenient remote placement.
- Cabinet
- 24 W × 32 H × 8 D in, 18-gauge stainless steel, about 100 lb. Wall-mounted on 16 in centers.
- Solution container
- 24 W × 12 H × 8 D in, 16-gauge stainless steel, up to 10 gallons. Mounted on the wall below the cabinet.
- Location
- Any convenient, ventilated indoor spot near your kitchen staff, where they can reach the container and hear the alarm. Not an unventilated enclosed closet, and not necessarily beside the cooking line.
- Nozzles
- Two atomizing nozzles on opposite sides of the exhaust duct, fed by separate air and solution tees, with their rear cleaning buttons within reach.
- Duct run
- At least 10 ft of duct between the nozzles and the exhaust discharge, so the mist has time to act.
- Lines
- Black 3/8 in air and red 1/4 in solution tubing, up to 100 ft per cabinet-to-tee-to-nozzle path. Corresponding tee branches should be relatively close in length.

Connected to your building.
Plan the water supply and the exhaust-fan connection with your project team.
- Cold water
- A 1/4 in copper supply, 80 PSI maximum, through a building shutoff valve. MOAS also has its own shutoff inside the cabinet.
- Dedicated circuit
- 120 VAC, 20 A, dedicated to MOAS, run in conduit from your electrical panel to the MOAS exhaust-fan interlock.
- Exhaust-fan interlock
- The exhaust fan has its own separate connection to the interlock. When the fan is on, the interlock lets power through to the cabinet; when it is off, MOAS cannot run. MOAS does not power the fan.
- Air and solution lines
- From the cabinet top to the two nozzles in the duct. One inch conduit is recommended for the two lines.
05
Will MOAS fit my kitchen?
Five things a site needs. Every MOAS is evaluated, configured and calibrated for its kitchen.

06
Easy to own.
- Maintain the solution level. The container holds up to 10 gallons of odor-neutralizing solution. Slide the lid forward to check the level or refill it; the tubes stay in place. Refill immediately when the alarm sounds, at approximately two gallons remaining.
- It tells you when it’s low. When solution runs low, a buzzer inside the cabinet sounds and the red light on top illuminates. Place the cabinet where staff can hear the alarm during working hours.
- Keep the nozzles clear. Once a month, while the MOAS and the exhaust fan are running, press and release the rear cleaning button on each nozzle several times. This helps keep grease buildup from obstructing the nozzle tips, so they can continue delivering mist into the exhaust stream.
- Service made easy. For maintenance or repair, authorized technicians or trained staff can open the cabinet door and access the system’s components directly.
