VIVOHOME HVAC Vacuum Pump and 4-Way AC Manifold Gauge Kit — 1/3 HP, 4.5 CFM, Portable Service Set

The VIVOHOME 1/3 HP 4.5 CFM vacuum pump and 4-way AC manifold gauge kit is a complete, portable solution for evacuating, diagnosing, and recharging automotive and HVAC refrigeration systems.

This all-in-one service kit combines a 4.5 CFM single-stage vacuum pump with a 4-way manifold gauge, color-coded hoses, leak detector and adapters so you can evacuate systems, check for leaks, and monitor pressures without hunting for extra tools. Built for both DIYers and pro technicians, the set balances straightforward operation with robust construction—aluminum housing, a copper motor, cooling fan and overload protection—for repeated field use.

How does this pump speed up system evacuation?

The 4.5 CFM motor clears air and non-condensable gases from lines faster than entry-level pumps, reducing wait time before charging systems. Its single-stage design is optimized for general automotive and light HVAC work, delivering dependable evacuation performance.

• 4.5 CFM flow rate for quicker vacuuming
• 1/3 HP motor that balances power and portability
• Exhaust filtration helps keep the workspace cleaner
• Cooling fan prevents heat build-up for continuous use

What readings and accuracy can I expect from the manifold gauge?

The included 4-way manifold provides both high and low side gauges with PSI/BAR dual units and four refrigerant scales on each dial, helping you read pressures for multiple refrigerants. The gauges are built with a shock-resistant core and deliver consistent readings suitable for diagnostics and charging.

• Dual-unit dials (PSI/BAR) with four refrigerant scales per gauge
• ±1.6% accuracy for reliable pressure checks
• Color-coded ports and hoses for fast setup
• Shock-resistant construction for field durability

Which refrigerants and systems is this kit compatible with?

The kit supports a broad set of common refrigerants, making it versatile for automotive air conditioning, residential HVAC servicing, and small refrigeration tasks. Hose fittings and included adapters help connect to different service ports and system types.

• Compatible with R134a, R410a, R22, R12, R502 and more
• Includes adapters and quick couplers for varied fittings
• Useful for automotive, HVAC and refrigeration maintenance
• Complete kit reduces the need for additional specialty tools

How easy is this kit to use for a beginner?

Color-coded hoses, clear gauges, and included accessories make setup and basic diagnostics straightforward for new users. The pump and manifold are packaged to minimize assembly steps, and safety features like integrated current protection add peace of mind during operation.

• Color-coded hoses to simplify connections
• Clear dual-unit dials for easy monitoring
• Beginner-friendly accessories: leak detector, oil, and adapters
• Overload protection and cooling fan for safer operation

Who is this for: The VIVOHOME vacuum pump and 4-way manifold gauge kit suits DIY enthusiasts who work on vehicle AC or home HVAC systems and technicians needing a compact service set for routine evacuation, leak checking, and refrigerant charging. If you require higher-capacity evacuation for large commercial systems, consider a two-stage or higher CFM pump; for most automotive and household HVAC tasks, this kit offers an efficient, dependable solution.
