Bacharach QV2

The Bacharach QV2 1.7 CFM Two Stage Rotary Vane Vacuum Pump

This is the perfect pump for the residential service technician. Attached to the TTT RapidEvac kit it is a solid performer. For residential, there is no advantage of using a larger pump for evacuation due to size of the lines used for evacuation and the serious resistance that they put on the rate of gas flow under high vacuum conditions. Remember, a perfect vacuum is -14.696 psig, the physics of vacuum is the limitation. A larger pump can create no more flow in a deep vacuum than a smaller pump when the line size becomes the limiting factor. Bigger is not always better. A small pump means less oil, less weight, and less current draw allowing lighter extension cords. Need more information on vacuum? Visit our vacuum training pages.

• High performance vacuum pump - Two models available: 1.7 CFM and 5.3 CFM
• Two stage design - The second stage of the two-stage design starts pumping at a lower pressure to pull a deeper ultimate vacuum
• Anti-oil-return - A check valve prevents pump-oil from entering the evacuated system after the pump stops
• Environment friendly - A built-in filter eliminates oil mist, and an oil-gas separator removes oil contamination from the exhaust
• Aluminum alloy motor casing - Motor utilizes strong light aluminum alloy, which guarantees cool, continuous operation
• Integrated design - The motor and pump are integrated to make the unit compact
• Large starting torque - Designed for low temperature and low voltage operation, the pump will start in temperatures =40°F (=5°C), at its rated input voltage of 110 VAC ±10%
• Oil circulation design - Offset rotary vanes work in conjunction with the vacuum pump oil to create high compression within the pumping chamber
• One year warranty
