Lincoln Mity-Vac Premium Fluid Evacuator features an integrated 2.3-gallon-capacity reservoir and measures 24" H x 12.4" W x 9.3" D. This lightweight, portable unit operates on compressed air to create a powerful venturi vacuum for draining fluids from tanks and reservoirs, and a 1/4" NPT compressed air hose attaches at the unit's base for stability. The fluid evacuator unit is made of durable, chemical-resistant polyethylene and features a large base with foot stabilizer, a quick-drain pour spout, and automatic overflow prevention. Accessories are included for draining engine oil or transmission fluid directly through the dipstick tubes, and a brake/clutch bleeding kit is also included for vacuum-bleeding hydraulic brake and clutch systems. This model evacuator has recently been enhanced to increase performance and reliability, featuring an improved lid gasket design to prevent the chance of leakage between the lid and reservoir, with an increased sealing surface area to ensure an airtight seal during vacuum and pressure applications. All six screws used to clamp the lid to the reservoir now feature new self-locking nuts to ensure that the lid remains securely clamped and wont loosen to allow vacuum or pressure leaks. In addition, the overflow shutoff valve has been redesigned to thread into the evacuator lid instead of being glued, ensuring the valve remains securely in place.
