15300 VacuMaster 3 CFM Vacuum Pump

The Robinair 15300 VacuMaster is a 3 CFM vacuum pump designed for automotive air conditioning service. It creates the deep vacuum needed to remove moisture and non-condensable gases from A/C systems before refrigerant charging. The unit is built for professional workshop use.

Suited for A/C evacuation tasks

This pump suits technicians who need reliable evacuation performance for standard automotive air conditioning systems. It is not intended for buyers who require a higher CFM rating for larger commercial systems or industrial applications. Users needing a different flow capacity should look at alternative specifications.

3 CFM flow rating

The defining specification is the 3 CFM displacement rating, which determines the evacuation speed for a given system volume. Match this figure to the manufacturer service requirements for the vehicles you service. The 15300 model number identifies this specific Robinair configuration.

Questions about this item

What manifold hose connections does the Robinair 15300 VacuMaster require to pull a vacuum on an A/C system?

Connect the pump inlet to a manifold gauge set using standard 1/4-inch or 3/8-inch flare hoses, then attach the manifold to the vehicle service ports.

Can the Robinair 15300 VacuMaster be used with older R-12 service gauges and hoses that are still in the shop?

Yes, the pump inlet accepts the same flare fittings used on R-12 manifold sets, so existing gauges and hoses connect directly.

How can I confirm the Robinair 15300 VacuMaster is pulling a proper vacuum after hooking it up?

Watch the micron gauge on the manifold; a steady deep vacuum reading that holds after the pump is valved off shows the pump is working.
