The 15400 has been engineered specifically for air conditioning and refrigeration service, and is built with Robinairs proven offset rotary vane for fast, thorough evacuation. Iso Valve Isolates the pump from the system with just a quarter-turn.
It allows the pump to be shut off while still connected to the A/C-R system, which is handy for checking rate of rise. With the valve handle in the OPEN position, the pump is open to the system being evacuated. In the CLOSED position, the pump is isolated from the system. The two-stage, offset, rotary vane design provides powerful, quiet, high vacuum capability and ensures moisture removal, while the high pumping capacity reduces evacuation time.
The two-stage design also cleans the system more thoroughly than a single-stage pump; the second stage starts pumping at a lower pressure so you can pull a deeper, ultimate vacuum. The intake filter prevents foreign matter from entering the pumping chamber, and an internal exhaust filter seperates oil vapor from the exhaust flow. A precise amount of atmospheric air is introduced into the pump, preventing condensation of moisture vapor and helping maintaing the purity of the pump oil. By using the gas ballast, the pump operates more efficiently and pump life is extended.The pump measures just 151/2 long, while aluminum housing and offset rotary vanes keep the pump weight low, making it easy to carry.
