Graver QMC Depth Pre-Filter Cartridges
Graver's QMC filters are manufactured from layers of melt blown polypropylene, which allows for high flow rates and ideal depth filtration characteristics.
With 95% efficiency at their rated micron level, they make an ideal and cost-effective pre-filter. Use a QMC filter in front of your final ZTEC WB filter to prevent clogging and improve flow rates.
Our stainless steel housings use P7 (a.k.a. Code 7) filter end types. Our polypropylene and plastic housings use AM filter end types.
