HVAC Vacuum Pump, 3 CFM Single Stage, 1.5 Gallon Chamber

Vacuum chamber and pump kit delivers fast, consistent evacuation for HVAC service and material degassing with a clear-lid chamber for easy monitoring. This single-stage rotary vane pump pairs with a 1.5-gallon stainless steel chamber to help pull deep vacuum for A/C work, vacuum packaging, or removing bubbles from silicone, epoxy, and resins. Built for steady runtime with copper motor power, cooling radiators, and an oil sight glass.

• Delivers 3 CFM pumping to pull down systems quickly for A/C vacuum evacuation and sealing work.


• Includes 1.5-gallon stainless steel chamber with 3/5" clear acrylic lid for at-a-glance bubble check.


• Reduces noise with dual silencers and a 50-micron air filter to limit debris and backflow into the chamber.


• Protects with oil viewing window, self-cooling radiators, and built-in thermal protection for safer operation.


• Supports multiple tasks from HVAC refrigerant service to resin/silicone degassing, essential oils, and polyurethane.

Set up your workspace with a vacuum system designed for clean pulls and straightforward control. The aluminum-alloy pump housing helps dissipate heat, while the copper motor keeps performance stable during demanding jobs. The chamber’s silicone gasket wipes clean after messy mixtures, and the reinforced hose adds durability for repeated use. Ideal for technicians, makers, and workshops needing reliable vacuum performance without guesswork—grab yours today and keep your next evacuation or degassing run on schedule.
