CAMFIL Farr Air Pollution Control (APC) now offers its Gold Series cartridge dust collector with an optional integrated HEPA safety monitoring filter.
Mounted on top of the collector so that no additional floor space is required, 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 capable of handling 2500 cfm (4248 cmh) of air per filter and rated to remove 99.97% of airborne particles of 0.3 micron in diameter and larger, claims Camfil.
Unlike some after-filters which are installed downstream of the fan with the filter at positive pressure, the Gold Series’ integrated design reportedly maintains the after-filter at negative pressure, preventing contaminated air from escaping in the event of a leak.
According to Camfil, recirculating dust collection systems are gaining in popularity because recycling of heated or cooled air back through the plant downstream of the collector brings significant energy savings.
