All equipment includes 2 m suction hose with rubber handle and a set of connectors, suction rod and bracket. Gravity collection is accomplished through a 20 liter volume height adjustable enlarged collection tray with splash proof mesh. When vacuum is created in the waste oil barrel, these devices can be cut off from the gas source and run autonomously. The device relies on a pump to apply a pressure of 0.5bar (3.5psi) and a 1.5 meter discharge hose to drain the waste oil. The equipment includes a relief valve to prevent excessive pressure.
