The unit should have an air-haindling capacity of 1,000 to 2,000 ft3/min (under "clean" filter conditions). The fan should be of the centrifugal type.,] . For large-scale abatement projects, where the use of a larger capacity, specially designed exhaust system may be more practical than several smaller units, the fan should be appropriately sized according to the proper load capacity established for the application, i.e..
