1/2 HP 5 CFM Vacuum Pump Air Conditioning Vacuum Pump 2 Stage Rotary Vane

1/2 HP Dual-Stage Vacuum Pump - 5 CFM Professional Grade 0.3 Pa Ultimate Vacuum in 3 Min - Motor Current Protection - Lightweight & Portable Product Overview This 1/2 HP (375W) dual-stage vacuum pump delivers 5 CFM flow rate and reaches 0.3 Pa ultimate vacuum in just 3 minutes. With integrated motor current protection, one-piece die-cast aluminum housing, and versatile refrigerant compatibility, it's a trusted tool for precise AC system maintenance and self-diagnosis. Key Features Optimal Performance Powered by a 1/2 HP (375W) motor running at 2880 r/min, the dual-stage vacuum pump delivers 5 CFM flow rate and reaches 0.3 Pa ultimate vacuum in just 3 minutes. Integrated motor current protection safeguards against overload or phase loss, ensuring reliable performance during its recommended duty cycle. Versatile Compatibility Engineered to support multiple refrigerants, compatible with R134a, R12, R22, R502, and can be used with R410a when paired with a 5/16-inch adapter (not included). Features both 1/4-inch SAE and 1/2-inch Acme intake fittings for flexible connection options. Durable Construction Crafted with one-piece die-cast aluminum housing for longevity and reliability. Robust design with two-pole pure copper motor ensures resistance against accidental drops. Ideal for self-diagnosis and recharging A/C systems, evacuating air prior to refrigerant refill while maintaining lightweight portability. Safe Operation Engineered with advanced motor current protection to prevent damage during extended use. 304 stainless steel coarse filter prevents contaminants from entering the pump chamber. Cotton layer filter at the exhaust port captures oil mist and impurities, ensuring clean operation and prolonging pump lifespan. User-Friendly Design Features ergonomic grip handle, intuitive ON/OFF switch, and simple oil fill port with clear oil viewing window. Bottom oil drain valve simplifies oil changes. Low-noise operation at approximately 65 dB, built-in cooling fan, and non-slip base guarantee comfortable portability and stable performance. Technical Specifications • Rated Power: 1/2 HP (375W)
