VIVOHOME 4 CFM Vacuum Pump and R134a Manifold Gauge Kit — 1/3 HP Single-Stage, Carry Bag & Leak Detector

The VIVOHOME kit pairs a 4 CFM single-stage rotary vane vacuum pump with a full R134a-compatible manifold gauge set and accessories for fast, reliable HVAC evacuation and recharging.

This all-in-one kit is built for homeowners, mobile technicians, and small-shop pros who need to evacuate, test, and recharge automotive or residential air-conditioning and refrigeration systems. The pump features a die-cast aluminum housing, visible oil sight glass and bottom drain port for straightforward maintenance, while the included manifold, hoses, adapters and leak detector supply the connections and diagnostics required for common refrigerants.

How quickly and deeply does the pump evacuate systems?

The single-stage rotary vane motor produces 4 CFM (cubic feet per minute) for efficient air and moisture removal from lines and evaporators. It reaches deep vacuums suitable for most automotive, split, window, and portable AC units, reducing contamination risk before refrigerant charging.

• 4 CFM airflow rate for faster evacuation
• Die-cast aluminum body for durability and heat dissipation
• High-volume cooling fan for extended run times
• Clear oil sight glass and bottom drain for clean maintenance

What gauges, hoses and adapters are included for refrigerant service?

The kit supplies a color-coded manifold gauge set with large, easy-to-read viewing windows plus three reinforced 5-foot hoses (red, blue, yellow) for high-side, low-side and service connections. Adapters and can taps are included so you can work with R134a and other common refrigerants; a 1/4"-to-5/16" adapter is provided for R410a compatibility.

• Durable manifold with shock-resistant cores and clear flow windows
• Three 5 ft reinforced hoses with brass fittings for leak resistance
• R134a can taps, quick couplers and R410a adapter included
• Compatibility across R134a, R12, R22, R502 and R410a systems

How is oil management and long-term reliability handled?

The pump includes a visible oil sight glass to monitor fluid level and a bottom drain port that simplifies oil changes without spills. A built-in cooling fan reduces thermal stress during extended evacuation tasks, and the lightweight ergonomic handle improves portability between jobs.

• Clear sight glass for fast oil checks
• Bottom drain port for clean oil replacement
• Included 0.35 qt (330 ml) pump oil to get started
• Anti-slip base reduces vibration and improves stability

Can this kit detect leaks and support DIY or professional work?

The included leak detector helps locate refrigerant loss and the manifold gauges provide accurate pressure readings for diagnosis and service. With quick couplers, can taps (piercing and self-sealing), and a protective carry bag, the kit is arranged for both mobile and workshop use.

• Handheld leak detector for quicker troubleshooting
• Piercing and self-sealing can taps supplied for different refrigerant cans
• Protective carry bag keeps components organized and transportable
• ETL listed pump for safety assurance under U.S. standards

Who is this for: This VIVOHOME vacuum pump and manifold kit is tailored to DIYers who service their own vehicles or home AC units, independent HVAC technicians who need a portable all-purpose set, and small repair shops handling 1–3 HP split, window and portable systems. It combines the essential evacuation, charging and leak-detection tools into one package for convenient onsite or garage use, but users should confirm refrigerant compatibility and follow safe charging and handling practices.
