SEQUENCE OF OPERATION
Stage 1 contaminated exhaust air enters the unit from the front side access.
Stage 2 exhaust air is scrubbed and stripped clean with a water, detergent and emulsifiers solution which removes 88% of PM, VOC’s and odors.
Stage 3 exhaust air enters the cyclonic module and is centrifugally dried; removing additional grease and suspended moisture that got past second stage.
Stage 4 the air passes through a bank of HEPA/DOP type primary filters.
Stage 5 a bank of activated carbon cells (not shown and usually not required) are used to capture any remaining odors.
In the final stage, the 98.7% cleaned exhaust air is discharged to the outside ambient air. “80% Return-Air” is not available for solid fuel cooking designs.
The contaminated scrubbing chamber solution is disposed into the grease trap1 and fresh solution is replenished automatically on a regular schedule.
