Camfil Farr Air Pollution Control (APC) has expanded its line of integrated safety monitoring filters (SMF) for Gold Series cartridge dust collectors. In addition to the current HEPA filters, the company now offers ASHRAE-grade filters where a more economical option is needed. Conveniently integrated on top of the collector, these after-filter modules prevent collected dust from re-entering the workspace if there should be a leak in the dust collector’s primary filtering system. The new ASHRAE filter module incorporates two Camfil Farr Riga-Flo filters rated at 95 percent ASHRAE efficiency (MERV 14) and capable of handling 2650 cfm (4248 cmh) of air per filter. The HEPA filter module has the same design and capacity but incorporates filters rated to remove 99.97 percent of airborne particles of 0.3 micron in diameter and larger. Both versions allow convenient access to the after-filters and easy change-out via the same platform used to access the primary filters. The integrated SMF design allows the total footprint of the dust collection system to be reduced.
