The Big Foot 40G Lake Pump Filter outer void gets filled with pea sized gravel or fiber filter media. In a short period of time the gravel developes moss which creates a very effective filter. A 2" foot-valve gets installed on the inner bung to maintain prime for the pump. Big Foot Filters are designed to be used as an initial filter on the suction side of a pump using surface water sources. The 80G, rated at 80 gallons per minute, is made of heavy duty PVC plastic. Extra large intake areas will require little or no service during the pumping season and will give many years of trouble free service, even under the most severe conditions. The 80G Filter's 12" diameter outside screen has an intake area of approximately 80 square inches and the 6" diameter inside screen has an intake area of approximately 33 square inches.
Rated at 40 gallons per minute in clear water.
Made of PVC, plastic and stainless steel.
