Professional Dual-Stage HVAC Vacuum Pump Kit 5 CFM Flow Rate - 0.3 Pa Ultimate Vacuum - ±1.6% Accuracy Gauge - Complete Refrigeration Tool Set Professional HVAC Service Solution This professional dual-stage HVAC vacuum pump kit delivers exceptional performance for demanding refrigeration and air conditioning service tasks. Featuring a powerful 5 CFM dual-stage vacuum pump, high-precision manifold gauge, and comprehensive accessory set, it provides everything needed for efficient system evacuation, charging, and diagnostics across multiple refrigerant types. Key Features Dual-Stage HVAC Pump Design
This dual-stage pump achieves deeper vacuums through preliminary vacuum and further pressure reduction, making it ideal for demanding HVAC tasks. Includes 1/2\" ACME and 1/4\" SAE ports, plus adapters (two R410a 1/4\" male to 5/16\" female, one 1/4\" male to 1/2\" female) for compatibility with R134a, R12, R22, R502, and R410a refrigerants. Powerful Motor Performance
Equipped with a 1/2 HP high-torque, 4-pole copper motor, the vacuum pump delivers 2880 RPM and a 5 CFM flow rate. It evacuates systems down to 0.3 Pa (22.5 microns) in just 3 minutes for faster, more efficient performance and thorough evacuation. Safe and Quiet Operation
An anti-backflow valve prevents oil backflow during sudden shutdowns. Integrated motor current protection prevents overload or phase loss that can lead to overheating or motor damage for reliable operation throughout its recommended 30-minute duty cycle. A high-volume fan, large mesh vent, and T-shaped heat fins enhance heat dissipation, keeping noise levels under 65 dB for a quieter work environment. Portable and User-Friendly Design
Easy to carry with an ergonomic handle and non-slip feet. The die-cast aluminum housing minimizes leaks, while the visible oil window allows easy monitoring of oil levels. A bottom drain valve simplifies maintenance, and the 304 stainless steel coarse filter blocks dust, while the cotton exhaust filter and metal filter remove oil mist. High-Precision ±1.6% Accuracy Gauge
This manifold gauge ensures precise pressure measurement for refrigeration systems. It features an oil-filled core to resist wear and a dry dial for better winter performance. A large sight glass allows clear refrigerant flow visibility, while color-coded gauges ensure accurate readings for refrigerant charging, diagnostics, and coolant recovery. Durable and Practical Construction
Built with a shock-resistant core to protect internal mechanisms, plus a calibration screw for zero-setting and scales for R12, R22, R134a, and R410a refrigerants. Its rubber-wrapped design ensures durability, while the aluminum body adds strength. A convenient hook allows for hands-free operation, making it both tough and practical. 4 Color-Coded Professional Hoses
Easily identify the high-pressure (red), low-pressure (blue), refrigerant adding (yellow), and vacuuming (black) hoses. Made of 3 reinforced rubber layers with a leak-proof seal, these 5-foot hoses are flexible, durable, and resistant to damage. Ideal for maintaining R134a, R12, R22, R502, and R410a air conditioning systems. Technical Specifications Rated Power: 1/2 HP (370W)
