Camfil Farr APC has expanded its line of integrated safety monitoring filters (SMF) for Gold Series® cartridge dust collectors. In addition to the current HEPA filters available for critical applications, 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. In addition, the SMF modules are now proven to function as flame arrestors for combustible dust on most recirculating applications.
