Announcing the QSL Series

Graver Technologies, LLC announces the release of the QSL™ Series filter cartridge which features a serial layer design to provide optimized prefiltration for critical membranes.  Incorporating a polypropylene microfiber media over a polyethersulfone membrane, the serial layered QSL cartridge design offers excellent reten­tion characteristics, superior flow and long-lasting protection of downstream 0.2 or 0.45 micron final filters. By preventing early blockage of downstream filters, the QSL contributes significantly to an economical overall design of a filtration system, making it an ideal filter for the clarification of particulate-laden solutions such as those found in food and beverage production, or a simplification of processes where multiple prefiltration steps are involved.
