Robinair 15501A-E-A2L is a compact 2-stage vacuum pump for HVAC/R evacuation work, with 128 L/min (5 CFM) flow, a 15-micron ultimate vacuum, 240 V power, and 1/4" plus 3/8" SAE flare intake ports.

It suits technicians working on residential and light-commercial evacuation jobs where A2L readiness, measurable vacuum performance, and job-site portability matter. If you work with R32 and want a Robinair pump that is easy to carry, quick to set up, and built for proper evacuation workflows, this is the model to compare.

FAQs

Is this pump suitable for R32?

Yes. This model is described as A2L-ready, and R32 is an A2L refrigerant.

Can I use it on R290?

No. This pump is not rated for A3 hydrocarbons such as R290.

What fittings does it have?

It uses 1/4" and 3/8" SAE flare intake ports.

Does it come with oil?

The page advises buyers to add vacuum pump oil before first use, so oil should be treated as a separate purchase unless product data is updated.

Do I need a micron gauge with this pump?

Yes. A micron gauge helps verify that evacuation is complete and gives you a measurable result instead of relying on time or pump noise alone.
