Lincoln Industrial 3637 Used Fluid Evacuator utilizes a powerful compressed-air-operated Venturi to quickly extract fluids from reservoirs or directly through a dipstick tube. This model features a stable tank design with two ball-bearing swivel casters and two fixed-axle wheels. It also includes a tool tray and tank-mounted clip for securing the discharge hose when not in use. Four flexible and two rigid wands are included, as well as dipstick tube adapters for BMW and Volkswagen brand vehicles. A built-in regulator reduces shop air pressure down to a safe level for evacuation and a backup safety valve prevents over-pressurization.
