Dust-collection filters are undaunted by high moisture
Camfil APC
The HemiPleat Synthetic dust collector filter cartridges (photo) combine a high-efficiency filter media with proprietary open-pleat technology, to provide reliable service in harsh, humid environments. The washable media is resistant to moisture and can handle heavy dust-loading conditions, as well as hygroscopic or sticky dusts that are generated in many food, pharmaceutical and chemical process applications. It uses a lightweight, 100% spun-bond polyester media in a pleated design, which maximizes surface area while maintaining open pleat spacing. It functions reliably at operating temperatures to 160°F. It is available in a standard version, or a nanofiber media version. The added nanofiber layer provides enhanced filtration efficiency. The standard media is rated at MERV11 filtration efficiency, and the nanofiber media is rated at MERV15 filtration efficiency, based on the ASHRAE 52.2 test standard. These filter cartridges are designed for the Farr Gold Series dust collectors, and can be retrofit on most major brands of competitive cartridge dust collectors, says the company. — Camfil APC, Jonesboro, Ark.
