In an effort to respond to the increasing synthetic media requirements in the air filtration industry, Purolator filters offer the SERVA-PAK S extended surface bag type. Highlighted below are design and function characteristics which make the SERVA-PAK S stand out from other bag air filters.
SERVA-PAK S is one of Purolator air filters that has an extended surface high-capacity air filter composed of individual dust holding pockets assembled in a metal support frame. A special multi-row stitching process performed on layers of ultra-fine glass bonded to a non-woven backing produces uniform spacing between each pocket, and provides optimum media performance while extending filter life.
Each pocket of this Purolator air filter is bonded and sealed to its own J-channel support frame, which is mechanically fastened to a heavy duty, corrosion resistant, galvanized enclosure frame. This design creates a rigid, air tight construction with a minimum of 85% open face area.
The SERVA-PAK S is available in a variety of bag air filters efficiencies, face sizes, depth and capacity combinations to accommodate most system requirements: limited fan static, high concentration of contaminants, limited filter bank face area, etc. Appropriate product selection will maximize performance.
