The Robinair 15500 has been performance tested to meet Robinair’s high standards. It features power and capacity for a wide range of service applications, a high CFM rating for fast, thorough evacuation and a two-stage rotary vane design. Features: Two-stage Design – 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; Oil Drain Valve – 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; Heavy-Duty Motor – High torque design for easy startup and efficient operation; and a Die-Cast Aluminum Housing – Cast aluminum housings make the pumps lightweight but durable.

Frequently Asked Questions
Can you tell the rated hp for this pump? I need one to easily keep 11 lbs vacuum using a pressure guage. Thanks!
1/3 hp. It will hold 28 to 30in Hg in smaller sealed systems, such as automotive AC. Note that vacuum in this unit is constant and increases up to about 30in Hg. The equivalent in PSIa (a = absolute) for 30in Hg is roughly 15 PSIa. Note also that you will require a vacuum gauge to monitor vacuum; not a pressure gauge.
Can the exhaust fitting (the big red plastic cap) accept a pipe fitting?
The big red cap is and exhaust valve. When you are pulling a vacuum the vapors and little oil come out from under the cap. Anything longer would likely impede the little bit of oil that does come out from under the cap.
Is oil included with the pump or do I have to purchase separately?
Included all you need in one box
