Robinair 15501 5 CFM 2 Stage Vacuum Pump

Robinair 15501 Two-Stage Vacuum Pump

The Robinair 15501 is listed as a two-stage rotary-vane vacuum pump with a nominal 5 CFM displacement. It is intended for compatible vacuum service, laboratory, HVAC, and other technical workflows where the pump’s actual performance and connection requirements match the system.

Before ordering, verify the exact supplied unit, electrical requirements, inlet fitting, operating range, ultimate vacuum specification, oil requirements, and any application-specific compatibility with the manufacturer’s documentation. The 5 CFM rating describes a nominal flow specification; it does not by itself establish the achievable vacuum in a particular assembly. Hoses, seals, connected vessels, and maintenance condition also affect system performance.

Operate and maintain the pump according to its manufacturer instructions, including appropriate ventilation, oil level checks, and routine service. Use only compatible fluids and fittings. For a separate oil option, see Robinair 13119 Vacuum Pump Oil; confirm that oil’s suitability for the exact pump before use.
