V-bank air filter uses thin mini-pleat filter elements in V patterns to increase the filtration area and lower the structure resistance in an effective way with features of high air flow rate, low resistance and long service life.V-bank air filters are mainly used in HVAC systems in the clean room including different efficiency ranging from medium efficiency (M6-F9), sub-high efficiency (E10-E12) to high efficiency (H13-H14) for options and also box type and W type for choices.
