ABSTRACT:
A workbench filtering station (10) includes a generally open interior in which a plurality of filter bags (50) are disposed to partially clean a gas stream. The gas stream is communicated to the bag filters (50) through an air intake (46). The air intake (46) is in the form of perforations in the side walls (44) of the filtering station (10). The station (10) includes HEPA-filters (60) which receive the partially-cleaned air from the bag filters (50). The HEPA-filters (60) clean the air to a clean-room environment. A fan (30) draws a constant volume of air through the filtering station (10) and exhausts the clean air into the room. In operation, a constant volume of air is drawn into the filtering station through the side intake panels. The air is communicated to a first filter station which is in the form of bag filters. The air is then passed through a HEPA-filter stage for further cleaning and exhausted to the room.
