RobinAir VacuMaster 5 CFM Vacuum Pump

Part No. ROB15500 Warranty Details  
115 volt, 2-stage design
Heavy duty motor - high torque design for easy start up and efficient operation
Die cast aluminum housing makes the pump lightweight but durable
Lifetime filtration - the intake filter prevents foreign matter from entering the pumping chamber, and an internal exhaust filter separates oil vapor from the exhaust flow
"No-hassle" over-the-counter replacement warranty HVAC high performance vacuum pump is engineered specifically for air conditioning and refrigeration service, and built with Robinair's proven offset rotary vane for fast, thorough evacuation. The two-stage, offset rotary vane design provides powerful, quiet high vacuum capability and assures moisture removal, while the high pumping capacity reduces evacuation time. Direct exhaust causes the exhaust to expel through the handle to direct it away from the service technician. Oil drain valve is positioned at the bottom of the oil reservoir and angled for faster, more complete draining. Oil fill port makes adding oil simple since the port is accessible from the front or either side. The sight glass on the front of the pump shows you when enough oil has been added. 1/2" ACME and 1/4" MFL intake fittings.

    Comments about RobinAir VacuMaster 5 CFM Vacuum Pump:

    I used this product to vacuum down the pressure in my Dodge Durango A/C system. It pulled the system down to a -29.9mmhg pressure rating very quickly. I believe the 5cfm vacuum pump may be stronger than what I needed for this particular job; however it made quick work of it today and will be useful for any bigger jobs in the future.

    One thing I don't like however is that the exhaust port has a plug (not a vent). Therefore while running the machine you have to be careful that nothing gets dropped in the small opening on top (b/c the Plug must come out to make the unit work).

    Overall I am happy with my purchase, and would recommend it to others who are doing an A/C vacuum job on one of their vehicles.

    • Q:

      I bought this unit for making skis/snowboards. While using it today for the first time I got some oil splatter and some sort of vapor out the exhaust port. Made the room look hazy. I followed start up procedures with filling the oil. Is this normal?

        Hi Rookie, glad to assist you! When the pump is running, the oil level should be even with the line on the sight glass. The pump will result in poor vacuum performance when the oil is not up to the level and the oil may blow from the exhaust if you overfill the same.
