Description
xMeet the SPECSTAR 3/4 HP dual‑stage HVAC vacuum pump paired with a 4‑way manifold gauge set, built to support professional air conditioning and refrigeration work without unnecessary complexity. This compact, portable system blends power, precision, and thoughtful design to help technicians work efficiently on residential and light commercial circuits. While you won’t promise instant results, you’ll discover a reliable partner for faster evacuations, thorough leaks checks, and smoother recharging workflows when conditions are favorable.
Powerful dual‑stage vacuum for demanding HVAC work
The vacuum pump uses a dual‑stage design to initiate a quick pull and then deepen the vacuum for a more complete evacuation. Its 3/4 HP copper motor delivers up to 3456 RPM with a 7.2 CFM flow rate, designed to reduce cycle times on typical refrigerant circuits. In optimal conditions, the unit can reach down to 0.2 Pa (1.5 microns) in about three minutes, supporting robust evacuation performance for precision work. The system’s capability pairs well with a range of refrigerants, making it a versatile choice for various service scenarios.
- Ports include 1/2” ACME, 1/4” SAE, and 3/8” SAE; adapters cover R134a, R12, R22, R502, and R410a
- Two‑stage operation helps manage heat buildup for longer sessions
Durable, user‑friendly design for real‑world use
Weighing 17.6 lbs with an ergonomic carrying handle, the pump balances portability with durability. The die‑cast aluminum housing minimizes leaks, while a visible oil window makes oil checks quick and easy. A bottom drain valve aids maintenance, and a 304 stainless steel coarse filter plus exhaust filtration help keep oil mist and dust out of the system.
- Quiet performance under 70 dB thanks to heat dissipation features and dual‑stage design
- Safety features include a thermally protected motor, anti‑backflow valve, and a current protector
Precise measurement and clear diagnostics
The accompanying 4‑gauge manifold delivers accurate pressure readings with a user‑friendly blend of dry and oil‑filled core technology. A large sight glass offers clear refrigerant flow visibility, while color‑coded gauges simplify charging, diagnostics, and recovery tasks.
- ±1.6% accuracy supports consistent readings across work orders
- Hooks and durable rubber wrapping add stability and longevity in busy shops
What’s included and how it helps on the job
Four color‑coded hoses (red, blue, yellow, black) make high‑pressure, low‑pressure, refrigerant addition, and vacuum connections easy to identify. The hoses are designed for durability and leak resistance, complementing the gauge set and ensuring a straightforward workflow from evacuation through recharge.
