5 Gallon Vacuum Chamber Kit, 3 CFM 1/4 HP Pump

5 gallon vacuum chamber kit delivers fast, reliable degassing and evacuation with a 3 CFM single-stage pump—ideal for HVAC A/C refrigeration service and clean resin work. The stainless steel chamber and clear acrylic lid help you monitor bubbles as they collapse, while the copper motor and aluminum housing support stable performance and heat dissipation. Built for workshop use, this kit includes the core components needed for vacuum degassing, silicone defoaming, epoxy resin, polyurethane, essential oils, and vacuum packaging tasks.

• Delivers 3 CFM flow with 1/4 HP power to pull vacuum quickly for HVAC evacuation and resin degassing


• Includes 5-gallon stainless steel chamber with clear lid for easy visibility during bubble removal


• Reduces noise using dual silencers plus a 50-micron air filter to limit backflow and block debris


• Protects operation with oil sight glass, self-cooling radiators, and built-in thermal protection


• Supports daily use with steel-wire reinforced hose and non-stick silicone gasket for easy cleanup

From pulling vacuum on A/C lines to stabilizing castings, this chamber and pump set is built for controlled, repeatable results. The pump’s non-backflow design helps reduce oil contamination risk, and the durable metal construction stands up to regular shop handling. Use it for refrigeration maintenance, automotive service, vacuum packaging, or material processing like silicone, epoxy, and polyurethane.
