pecially optimized for relatively small collection sites like 2mx2m square pits, this machine utilizes a patented double float mechanism to ensure superior surface tracking and steady oil collection even during liquid level fluctuations. The system features a standard inverter that enables non-step control of the pump's rotation speed, balancing the float's inflow rate with the pump's output to prevent unnecessary oil-water stirring and significantly improve separation efficiency. Designed to handle demanding maintenance environments, it is equipped with a robust SUS304 stainless steel oil separator that withstands high-temperature fluids, alongside a standard patented large-size scraper mechanism that powerfully forces out undrainable animal or vegetable food oils, as well as low-fluidity paint and bonderized residues.
