Camfil Air Pollution Control (APC) says its new HemiPleat synthetic dust collector filter combines a high efficiency synthetic media with proprietary open-pleat technology for exceptional performance and long life in harsh, humid environments.
The washable media is resistant to moisture and can handle heavy dust loading conditions and/or hygroscopic or sticky dusts generated in pharmaceutical, food and many other processes.
The HemiPleat synthetic filter uses a lightweight, 100% spun bond polyester media in a pleated design that maximises surface area while maintaining open pleat spacing.
Camfil APC says the 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. Sturdy and durable, 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 fibre media version that uses Camfil APC’s proprietary eXtreme media technology. The nano fibre 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 fibre 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, the company said.
