The “Drain & Pressurize” method employs the benefits of the drain & evacuate system without an evacuation pump— the fluid drain is pressurized to evacuate the used fluid.
Model 3630 series used fluid drains
Lincoln’s 3630 series of portable used fluid collection equipment offers solid construction and outstanding features that set them apart from the competition.
All three models feature a 25 gallon (95 liter) welded-steel tank supported by heavy-duty 4 in. (102 mm) swivel casters and 6 in. (150 mm) fixed-axle
wheels. Emptying the tanks requires only shop air and a standard tire chuck.
Model 3639 combination used fluid drain and evacuator combines the features of the 3635 drain and 3637 evacuator into a single unit, giving operators the choice to collect fluids by gravity from lift-mounted vehicles or using a venturi to extract fluids directly from reservoirs or through a dipstick tube.
