The SPECSTAR vacuum pump and gauge set is designed to measure pressure in refrigeration equipment and extract gas to obtain a vacuum, meeting high vacuum standards. It is perfect for those who are looking for self-diagnosing or recharging AC systems. This vacuum pump and gauge set is perfect for automotive air conditioning, HVAC work, refrigeration, and various industrial applications requiring high vacuum pull from a compact pump.
- 4.5 cfm single-stage vacuum pump features a 1/3 HP high-torque, 4-pole pure copper motor that minimizes wear and maximizes efficiency
- 4.5 CFM flow rate and the ability to evacuate systems down to 2 Pa in just 3 minutes, it ensures a faster, more thorough evacuation for a cleaner, more efficient process
- Vacuum pump includes 1/2 in. acme and 1/4 in. sae ports, along with 2 r410a ¼ in. male to 5/16 in. female adapters and one 1/4 in. male to 1/2 in. female adapter, making it compatible with r134a, r12, r22, r502, and r410a systems
- With a 4.5 cfm high flow rate, it’s ideal for 1-3 hp split a/cs, 1-2 hp central a/cs, 1-3 hp small commercial a/cs, and vehicle a/c systems
- Thermally protected motor shuts down if it overheats for long-lasting performance
- An anti-backflow valve prevents oil backflow during sudden shutdowns, while a current protector safeguards the motor
- Weighing just 17.6 lbs. this pump is 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
- Large sight glass allows clear refrigerant flow visibility, while color-coded -Gauges ensure accurate readings for refrigerant charging, diagnostics, and coolant recovery
- Built with a shock-resistant core to protect internal mechanisms, this -Gauge includes a calibration screw for zero-setting and scales for R12, R22, R134a, and R410a refrigerants
- 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 hoses are flexible, durable, and resistant to damage
- Package included 1 x 4.5 cfm vacuum pump, 1 x ±1.6% accuracy manifold gauge, 1 x 5 ft high strength 4-color hoses, 1 x leak detector, 1 x 0.35 qt./330 ml bottle of vacuum pump oil, 2 x r410a fitting adapters (1/4 in. male to 5/16 in. female), 1 x fitting adapter (1/4 in. male to 1/2 in. female), 1 x r134a self-sealing can tap, 1 x r134a puncture can tap, 2 x quick coupler adapter, a pair of gloves, 1 x screwdriver, 1 x valve core tool, 3 x top pins, 4 x sealing gasket, 1 x ptfe tape, 4 x O-ring
- Pump oil type viscosity grade 46
- Recommended oil capacity 0.27 qt. (260 ml)
- Air inlet ports 1/4 in. sae and 1/2 in. ACME
- Vacuum total pressure 150 microns ultimate partial vacuum 2 Pa (15-microns)
