Johns Manville Launches Extended Air Filtration Product Line at Techtextil Exhibition 2007 in Frankfurt

CombiFil® Premium is an innovative multi-layer composite that is setting new standards for air filtration performance. It combines the advantages of both polyester spunbond and micro glass and provides a filtration product that has consistent mechanical filtration efficiency up to HEPA, low-pressure drop with high dust-holding capacity and requires no additional reinforcements. As a result, it is easy to process and provides an extremely long filter life with low energy usage. It allows filter producers to manufacture pleated filters utilizing new dimensions of high dust-holding capacity combined with high stiffness and low pressure drop.

SpunFil™ EasyPleat is a calendered polyester spunbond made with John's Manville's new BC-technology. It has high air permeability and features a very high stiffness even at low-area weights of between 60 and 120g/sqm. The product enables high pleating machine speeds while continuing to achieve sharp and precise pleats.
