ABSTRACT:
A clean air cabinet includes a blower chamber and a sample chamber separated by a filter. A blower within the blower chamber forces air through the filter into the sample chamber. A perforated wall between the sample chamber and the filter provides a pressurized zone between the wall and the filter. An exhaust plenum connects the pressurized zone with an exterior of the cabinet. A cap is provided to close off the plenum when the blower is not operating.
