🔴 Robinair (15500) VacuMaster Economy Vacuum Pump - 2-Stage, 5 CFM, Red: High-Performance and Affordable Solution Review

Great pump. If your hose is fitted with a Schrader valve you may need an adapter when using R134 automotive gauges.

A pump and refill cost more than this pump (including freon and oil). Easy setup, quiet, good vacuum cleaner.
