The new HemiPleat Synthetic dust collector filter from Camfil Air Pollution Control (APC) combines high-efficiency synthetic media with proprietary open-pleat technology. The washable media is resistant to moisture and can handle heavy dust loading conditions and/or hygroscopic or sticky dusts. The HemiPleat Synthetic filter uses a lightweight, 100% spun bond polyester media in a pleated design that maximizes surface area while maintaining open pleat spacing. According to Camfil, wider spacing of the patented HemiPleat design exposes more media to the air stream, resulting in lower pressure drop and improved dust release during pulse cleaning. This moisture-resistant media may be washed and reused in many applications with operating temperatures up to 160°F.
HemiPleat Synthetic is available in a standard version or a nano-fiber media version that uses Camfil APC’s proprietary “eXtreme” media technology. The nano-fiber layer acts like a pre-filter that enhances surface loading of dust, keeping most particles from embedding in the base media. This enhances the filter’s efficiency as well as its cleaning ability for longer service life. The standard media is rated at MERV 11, and the nano-fiber media is rated at a MERV 15 filtration efficiency based on the ASHRAE 52.2 test standard. HemiPleat Synthetic filters are available for Farr Gold Series dust collectors or for retrofit on most major brands of competitive cartridge dust collectors.
