Extended-life filter bags improve filtration processes


The polypropylene or polyester needle felt construction of the DURAGAF extended-life filter bags, along with the increased thickness of the filter material, significantly increases the dirtholding capacity and extends the lifetime by two to five times longer than standard needle felt filterbags. These features significantly reduce operating costs. In addition, the needle felt material with smaller diameter fibers also provides a more porous filter material while maintaining the same low initial differential pressure.
