VIVOHOME 110V 1/3 HP 4CFM Single Stage Rotary Vane Air Vacuum Pump

The VIVOHOME 110V 1/3 HP 4 CFM Vacuum Pump Kit provides a complete setup for evacuating moisture and servicing air conditioning and heat pump systems. Built for both automotive air conditioning and residential HVAC work, it packages a single-stage rotary vane pump together with diagnostic gauges, hoses, and adapters so you can prepare lines before adding refrigerant.

At the center of the kit is a 4 CFM pump built with a die-cast aluminum body, an ergonomic carry handle, and an anti-slip base. A high-volume cooling fan is integrated directly into the housing to assist during extended operation. Keeping track of maintenance is straightforward thanks to the built-in sight glass for viewing fluid levels, along with a bottom drain port for clean oil changes. The kit also supplies an initial 0.35-quart (330 ml) bottle of vacuum pump oil.

The included manifold gauge set is paired with three 5-foot reinforced hoses in red, blue, and yellow for clear line management. It features a shock-resistant core and a large viewing glass to monitor refrigerant flow during servicing. Broad system compatibility is a key strength: it connects to systems using R134a, R12, R22, and R502, while the included 1/4-inch to 5/16-inch adapter allows direct hookups to R410a equipment, including mini-splits and window units.

Because this package includes both self-sealing and piercing-style R134a can taps, you need to check your specific refrigerant canister to ensure you attach the right fitting. In addition, this unit uses a single-stage rotary vane mechanism powered by standard 110V power, which requires access to an electrical outlet during field use.

Verdict: The VIVOHOME 4 CFM Vacuum Pump Kit is an all-inclusive solution for DIYers and technicians needing to service car air conditioners, residential split systems, or heat pumps. If you want a ready-to-use package with gauges, hoses, leak detection, and oil in one bag, this set covers the essentials.

• Power: 1/3 HP
• Voltage: 110V
• Flow Rate: 4 CFM
• Pump Type: Single-stage rotary vane
