Typical grease filters in the cooker hood itself is only for controlling the large grease particulates generated during the cooking process but are ineffective in removing the finer grease particulates , oil mist, cooking fumes, smoke and odors. These pollutants build-up in the ducts, blower, roof and outside walls of the building, are highly flammable and frequently cause fires.

The AK-Series, our high performance kitchen exhaust air cleaner provides effective containment for air pollutants and prevents possible fire hazard and reduces air duct cleaning maintenance while keeping the air free of annoying smoke and greasy odors. The treated air can then be re-circulated back to the airstream or expelled out of the building.

These air cleaners are designed based on the principle of Electrostatic Precipitation*, with high efficiency filtration and odor absorption filters. The efficiency rating is 95% for particles of 0.01 micron in accordance with ASHRAE Standard.

*Electrostatic Precipitation: The removal of very fine particles suspended in a gas by electrostatic charging and subsequent precipitation onto a collector in a strong electric field.

How AK series works

Contaminated air is drawn by the blower through a washable metal mesh pre-filter, which traps large dust particles. The remaining particles, some as small as 0.01 micron, pass into a strong electrical field (Ionizing section -12.5 kV ~13KV) where the particulates receive an electrical charge. The charged particles are then drawn into a collecting plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with the same polarity (collecting section- 6~7KV) as the particles, which repel, while the interleaving plates are grounded, which attracts and collect the contaminants. An after-filter will then complete the air cleaning process.
