What determines the number of air cleaners required in a facility?
It is necessary to clean the pollution out of the air as fast as it is being produced to prevent accumulation. In air cleaning jargon this is called Air Changes per Hour (ACH), which means all of the air in a shop passes through the filters X times per hour. After 30 years, we know for sure that 8 ACH is best for body shops. So the air cleaning capacity of a given air cleaner model, combined with the total volume of a shop and the required 8 ACH determines the number of units required in a given facility.
