It eliminates air pockets, doesn't require electricity or batteries, is environmentally safe, and a remote operation is available. In addition, it has two 10 gallon capacity, clear fiberglass tanks, operates with or without shop air, and offers color-coded control valves for easy distinction and use. No hoses to disconnect and no spills on the shop floor. Made in the U.S.A.
