Gold Series cartridge dust collector

This firm’s Gold Series cartridge dust collector is now available with an optional integrated high-efficiency particulate air (HEPA) filter that is 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 in case of a leak in the dust collector’s primary filtering system. It is a required component in recirculating dust collection systems that filter hazardous dusts and recycle air downstream of the collector. Each module incorporates two HEPA filters capable of handling 2,500 cfm (4,248 m3/h) of air per filter and is rated to remove 99.97% of airborne particles 0.3 µm in diameter and larger. Unlike after-filters that are installed downstream of a fan and a 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.
