The Gravity Feed Filter Scavenger is a two piece housing designed to float an oil/water separator cartridge at the oil/water surface of a holding vessel. Once floated on the surface and its output hose is connected, it is ready to start recovering product.

The Gravity Feed unit consists of three basic parts, the buoy base, the cartridge and the lid. As the buoy recovers oil, the output hose fills and sinks allowing oil to drain through it. The output hose can also be held in a submerged position with the provided clamp on ballasts and floats which are shipped on the hose.
