3F Series Floating Weir Skimmers

3F Weir Skimmers Resolve Spills, Help Improve Plant Efficiency and Protect the Environment

Practical and Efficient Skimming with 3F Series Floating Weirs

3F Series LogoThe Oil Skimmers, Inc. line of 3F floating weir skimmers is 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 ability to adjust to fluctuations in liquid level. Also, similar to our tube-type skimmers, 3F weir maintenance downtime is low as there are few moving parts 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.


3F 360-Degree

3F Series 360-Degree Floating Weir Skimmer

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 prior to separation or further wastewater treatment. A mesh screen surrounds the center weir to prevent intake of debris and clogging of the skimmer.
