Uniweld HVP12 Humm-Vac 12 CFM Vacuum Pump

The all-new Uniweld exclusive Humm•Vac pumps remove moisture and dehydrate a system quickly and efficiently. The rugged tough chassis, powerful, quiet running 110/220V, 50/60Hz motors, lighter weight and ergonomically designed features make these pumps the #1 choice to go to to work with you. Whether you work in the HVAC industry, lab, or on the manufacturing floor, this is the pump for your applications. The lightweight design and rugged construction withstands even the most demanding environments. Dual-stage pumps feature two pump units connected in series which are driven from the same shaft to create vacuum levels as low as 5 x 10–2 Torr.

Large-finned die-cast aluminum oil reservoir extends time between oil changes and helps limit overheating. All models have an isolation valve to prevent oil suck-back into the system, angled low-profile oil drain for fast and complete oil changes, and large sight glass on oil reservoir to monitor oil level and condition. Center-balanced handle makes transportation easy and clean with no oil spills.

Industrial belt drive models are built for industrial and laboratory applications. Both units have a larger than normal oil reservoir, ensuring extended pumping efficiency with few oil changes.
