Camfil Farr Air Pollution Control Adds Filter To Dust Collector

Camfil Farr Air Pollution Control (APC) says it is now offering its Gold Series cartridge dust collector with an optional integrated HEPA safety-monitoring filter.

Mounted on top of the collector, this after-filter prevents collected dust from re-entering the workspace if there should be a leak in the dust collector's primary filtering system. It is a required component in recirculating dust-collection systems that recycle air downstream of the collector when filtering hazardous dusts.

Each module incorporates two HEPA filters that are capable of handling 2500 cfm (4248 cmh) of air per filter and rated to remove 99.97% of airborne particles measuring 0.3 micron in diameter and larger, the company says. Unlike some after-filters that are installed downstream of the fan with the filter at positive pressure, the Gold Series' integrated design maintains the after-filter at negative pressure, preventing contaminated air from escaping in the event of a leak.

The design also allows convenient access to the HEPA filters and easy change-out via the same platform used to access the primary filters, Camfil Farr APC adds.
