Remark:1. The capacity was tested under 0.7 MPa working pressure. When choosing filter, decision should be made according to the actual working pressure after correction. 2. “*” indicates the filtration grade of filter elements. Grades E9, E7, E5, E3 and E1 are optional.Technical parameters Model Capacity(m2/min) Working pressure(Mpa) Connection size Height(mm) Connection distance(mm) Weight Kg Filter element Qty RF12-* 0.57 ≤1.6 1/2" 281 105 3.6 1 RF16-* 1.00 ≤1.6 1/2" 281 105 3.7 1 RF20-* 1.72 ≤1.6 1/2" 340 105 3.9 1 RF24-* 2.90 ≤1.6 1" 389 133 4.4 1 RF28-* 4.90 ≤1.6 1" 497 133 4.6 1 RF32-* 7.20 ≤1.6 11/2" 579 164 4.8 1 RF36-* 11.00 ≤1.6 11/2" 693 164 5.1 1 RF40-* 14.00 ≤1.6 21/2" 789 194 12.7 1 RF46-* 18.00 ≤1.6 21/2" 935 194 15.0 1 RF48-* 22.00 ≤1.6 21/2" 1091 194 17.2 1 RF54-* 29.00 ≤1.0 DN80 1219 406 41.3 2 RF56-* 36.00 ≤1.0 DN80 1219 406 41.3 2 RF60-* 54.00 ≤1.0 DN100 1245 413 54.4 3 RF64-* 72.00 ≤1.0 DN100 1327 508 81.2 4 RF68-* 89.00 ≤1.0 DN100 1327 508 82.6 5 RF72-* 143.00 ≤1.0 DN150 1387 610 123.0 8 http://www.air-separate.com/pid10191386/Filter.htm
