ABSTRACT:
An airborne particle removal system includes a vacuum assembly to introduce a flow of air into a housing. A cyclone dust collector is positioned in the housing downstream of the vacuum assembly with respect to the flow of air through the housing. A plurality of filter bags is positioned in the housing downstream of the cyclone dust collector with respect to the flow of air through the housing. A plurality of high efficiency particulate air filters is positioned in the housing downstream of the filter bags with respect to the flow of air through the housing. In certain preferred embodiments, a liquid distribution system introduces a liquid agent into the system.
