Hermit Oil Skimmer

The Elastec Hermit Oil Skimmer (Specs) is designed to access tanks through roof or side manway openings with a minimum diameter of 20 in / 50 cm. Driven by an explosion-proof* air motor, the lightweight skimmer can work unattended recovering a variety of oil types. Supplied with an optional air-operated diaphragm pump, it recovers the oil with little water content. Fill out our questionnaire and tell us about your project.

Resembling a “hermit crab”, its broad, buoyant "claws" direct the flow of oil into the rotating smooth drum where it is scraped into a trough and pumped into a storage tank. The setup is best suited to fixed fluid level tanks. The tank oil skimmer is supplied with 10 ft / 3 m of air and suction hose with a grounding wire and in-line strainer.
