The sand filter can filter 17000 L per hour and features a durable, corrosion-proof filter tank that is resistant to the acidic influence of chlorinated pool water. There is also an additional prefilter to keep dirt out of the coarse sand filter. It has a multiport valve for easy control and an easy-to-read pressure gauge. The top flange clamp design allows 360 degree rotation for easy installation. For secure mounting, this set includes a fixable base. Thanks to the reinforced plastic housing, this pool filter pump is weatherproof and durable. It is compatible with most above ground pools with a 3.8 cm port. Note: It can be connected with both diameter 32 mm and diameter 38 mm hoses.
