ABSTRACT:
The invention provides a method of filtering air within an enclosed space which includes the combination of a fan and air filtration media, which is positioned relative to the fan so as to avoid aerodynamic and mechanical vibrations within the filter media. The filter is positioned relative to the fan such that the airflow passing through the filter will be within the laminar regime. The filter is connected to the fan or to a structural element within the enclosed space by vibration isolation units, which serve to dampen or eliminate mechanical vibration within the filter media caused by the operating fan. The invention provides efficient dust collection by virtue of the low velocity, laminar airflow through the filter, and greatly reduces release of dust particles from the filter media by virtue of the reduction of vibration within the filter media.
