The QSL serial layered filter cartridge offers longer service life with less prefiltration requirements. With an absolute retention rating of 99.98% at 0.5 micron, the QSL is an ideal polish filter for cannabis processing. It also works well as a pre-filter for 0.2 micron and 0.45 micron membrane filters in wine and beer bottling.
Its serial layered design consists of a polypropylene microfiber media over a polyethersulfone membrane. The high surface area dual layer construction ensures a high flow rate, long service life, and lower maintenance costs.
