Vacuum Pumps

HIGH VACUUM PUMPS

Model 15234 - A high performance, lightweight pump engineered specifi- cally for small system and appliance service. Offset rotary vane design cre- ates deep vacuum conditions necessary for thorough system evacuation. Work- ing in conjunction with the vacuum

pump oil, the vanes develop a powerful compression, reducing system pressure until moisture vaporizes and is eliminated along with the exhausted air. Features include an integral check valve to prevent pump oil from being sucked into the system if power is interrupted during evacuation, 1/8 HP capacitor start motor with built-in overload protection, rugged polycarbonate plastic handle and base. 115v AC operation.

Model 15400 - CoolTech pumps are designed for heavy duty refrigeration and air conditioning service, but are lightweight for easy portability. Proven offset rotary vane design provides high vacuum capabilities for thorough evacuation and fast pulldown. Features include Robinair’s exclusive Iso-Valve™ which isolates the pump from the system when evacuation is completed to allow accurate vacuum readings and to return pressure in the pump to normal, 1/3 HP high torque motor, internal ball check valve, die- cast aluminum pump housing, Lexan® handle and base. 115v AC operation.

Model 15600 - Same design and construction as Model 15400 above, but equipped with 1/2 HP motor and increased 6 CFM capa- bility for fast evacuation of large systems.
