PROPISTON OIL SKIMMER

The PROPISTON OIL SKIMMER is a screw-tube tramp-oil recovery unit engineered for CNC machine tools and water-soluble coolant tanks. Unlike conventional disc-type and chain/belt skimmers, it uses a screw rotating inside a tube to scrape surface oil directly into the recovery tube — eliminating the gravity separation tank and delivering maintenance-free, cleaning-free, high-purity recovery.
Key features:
Exclusive screw-tube recovery — A specially structured screw rotates within the tube, scraping the oil film directly from the fluid surface. The short recovery path ensures stable efficiency and low water content in the recovered oil.
Truly maintenance-free — No belts, scrapers, or other wear parts, removing the need for replacement and adjustment, and lowering long-term operating costs.
No cleaning downtime — Without a gravity separation tank, there is no sludge build-up and no periodic shutdown for tank cleaning, keeping the line in continuous operation.
Compact, space-saving design — A slim vertical structure mounts directly onto existing coolant tanks, requiring no modification and no extra floor space.
Stable continuous operation — Geared-motor driven for long-duration recovery, with a transparent observation chamber for real-time monitoring.
