US Vacuum "HVAC" series vacuum pumps are TWO-STAGE Rotary Vane Air-Cooled vacuum Pumps capable of producing an ultimate vacuum of 25 Microns (0.025 mmHg).

Both the HVAC 3&5 pumps features a compact, simple design with quiet air-cooled operation. Standard Features include:  direct drive 110V motor, power cord, on-off switch, carrying handle, rubber mounting feet and discharge air baffle. Additionally, the pumps come with an inlet adapter fitting for 1/4" SAE & 3/8" SAE connections (if required).

All HVAC pumps are ideally suited for use in applications requiring high vacuum such as automotive & commercial air conditioning systems, vacuum ovens, freeze fryers, vacuum degassing & others.

HVAC series pumps are made for ultra-high vacuum applications. Prolonged operation at pressures above 10 mmHg (10 Torr)
may result in pump damage. For application above 10 Torr, please see our CPS series of pumps (CPS-5B, 8B, 15B)
