Air Filtration System

Many workspaces in the food and packaging industry are required to be totally enclosed in order to be free from any atmospheric contamination.
However, when the workspace is enclosed and air-conditioning cannot be applied due to the presence of heat source, the workspace can be very unbearable for the workers to stay inside. A practical approach is to utilize the Open Space Cooling system with an air-filtration unit.

G4 Filtration Standard

We typically combine the Open Space Cooling system with G4 Air Filters which will remove 80% of the air-borne particles larger than 10 micron size (10 micron size is the size of flower pollen). The G4 class air filter is made of synthetic material which is replaceable.

The G4 Class Air Filter system is in accordance with BS EN779 European Standards which filters 80-90% of air-borne particles of size more than 10 micron.
