Big Foot - 80-G Strainer

Bigfoot 80-G Strainer

Big Foot Filters are designed to be used as an initial filter on the suction side of a pump using surface water sources. The 40G and 80G, rated at 40 gallons per minute and 80 gallons per minute respectively, are 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 40G uses the 6″ diameter screen on the outside and 2″ diameter inside screen with 1/8″ slots with an open area of 20 square inches. 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.

Both the 40G and 80G can be ordered equipped with a check valve and can be ready to connect to your pump. The area between the two screens can be ordered filled with bulk-filter matting which has been produced from the finest raw materials and certified fish-safe by an independent bio-assay lab using standard EPA test protocols. The filtering media will provide an effective means of keeping algae and other forms of marine life out of the pumping system. In addition, the extra large inlet area reduces entrance velocities to the point that foreign matter is not picked up by the suction. Also, the large filtering area can retain a substantial amount of foreign matter before it needs service. For applications requiring greater capacity these units can be installed on a manifold.

Specifications:

• Rated at 80 gallons per minute in clear water.
• Made of PVC, plastic and stainless steel.
• 12″ outside screen and 6″ inside screen with 2″ suction connection.
• 12″ screen has approximately 1600 ¼ holes with total open area of approximately 80 sq. inches.
• 6″ screen has approximately 680 ¼ holes with total open area of 33.3 sq. inches.
• 2″ check valve – optional.
• Bulk-filter matting – optional.

Recommendations:

• Avoid putting excess stress on the 2″ suction connection.
• The Filter can be installed vertically or horizontally.
• If pea gravel is used as the filtering media, be sure it is larger than 3/8″ in diameter and irregularly shaped. Round pea gravel tends to fill the inlet holes and reduces capacity. Reassemble the top being careful not to overtighten the stainless steel tie rods.
• For best results, avoid setting unit directly on the bottom in muddy, weedy or sandy conditions. It is recommended to place on a cement block or similar object when installing.
