3F Series Floating Weir Skimmers, Oil Skimmer

3F 360 Degree and 3F Flow Control

The Oil Skimmers, Inc. line of 3F floating weir skimmers are easily deployable and well-suited for a wide range of oil removal jobs. 3F Series weirs work in sumps, above-ground storage tanks, parts washing tanks, equalization tanks, oil/water separators, and on settling and leachate ponds, lagoons, or open water where selective adhesion skimming is not applicable. Built of long-lasting 304 or 316 stainless steel, 3F units are lightweight and compact, yet rugged and able to deliver dependable skimming results month after month, year after year.

3F Series skimmers share several advantages with Oil Skimmers, Inc. proven tube-type skimmers, including continuous operation and the ability to adjust to fluctuations in the liquid level. Also, similar to our tube-type skimmers, 3F weir maintenance downtime is low as few moving parts are requiring regular service. If you need to remove large quantities of oil in a limited amount of time and accomplish that removal at high rates, 3F Series Floating Weir skimmers are the solution. These skimmers can be set up easily by one person - a distinct advantage when fast spill response is required, or if a sudden increase in capacity occurs.

The 3F 360 floating weir skimmer features 3 floats and a central intake weir capable of skimming oil from all directions (360 degrees). The center weir can be adjusted to take more or less of a cut of the oil layer on the water's surface. Ideal for spill clean up, or as the first stage of oil removal before separation or further wastewater treatment. A mesh screen surrounds the center weir to prevent the intake of debris and clogging of the skimmer.
