Fiberglass Enviro-Pak Bag Pocket Filters - 65% Efficiency

The Airex Enviro-Pak bag filters are designed for use in most commercial or industrial HVAC systems where medium to high efficiency filtration is required. Enviro-Pak bags are available in a variety of standard and odd sizes in four different efficiencies: 45-50%, 60-65%, 80-85%, and 90-95% with a MERV rating of 10 to 14. Each filter pocket is attached to a 26 gauge galvanized steel frame that is in turn inserted and locked into a 24 gauge galvanized steel double turned header. This rugged assembly prevents warping and provides an open filtering area of not less than 90%. Each pocket is designed to allow full inflation while maintaining adequate air exit space between adjacent pockets. Each pocket is divided into channels by “span-link” stitching which gives the pocket its unique configuration. The Enviro-Pak bag filter is available in either synthetic (recommended) or micro-glass media. The following test data is based on glass media and when replaced with synthetic (P) media, the initial resistance (W.G) is approximately ten percent less than the glass fiber bag on average. For areas where moisture is a concern we recommend a polyester media always be used.
