VIVOHOME 1/3 HP 5 CFM Vacuum Pump & 4-Way AC Manifold Gauge Set — 5 CFM, Multi-Refrigerant

The VIVOHOME 1/3 HP 5 CFM vacuum pump and 4-way manifold gauge set is a complete evacuation, testing, and recharge kit built to speed up AC service and give stable, accurate pressure readings.

Designed for automotive and small HVAC work, this all-in-one kit combines a 5 CFM single-stage vacuum pump with a four-way manifold gauge, color-coded hoses, adapters, leak detector, and accessory oil so you can evacuate, diagnose, and refill refrigerant with fewer extra tools. Rugged construction, current protection, and multi-refrigerant compatibility make it suitable for professionals and informed DIYers who want dependable performance on varied systems.

How quickly will this pump evacuate an AC system?

The 5 CFM (cubic feet per minute) single-stage pump moves air and non-condensable gases efficiently for small to medium systems, shortening evacuation time compared with lower-capacity units. The integrated cooling fan and exhaust filtration help maintain steady operation during extended use.

• 5 CFM displacement for faster vacuuming of automotive and residential systems
• Single-stage design adequate for standard HVAC and refrigeration service
• Cooling fan prevents thermal slowdown during longer evacuations
• Exhaust filter reduces particulates in the work area

What measurements and accuracy does the manifold provide?

The included four-way manifold gauge gives dual-unit PSI/BAR readouts and four refrigerant scales per dial, making it straightforward to read pressures for common refrigerants. The gauges are built with a shock-resistant core and deliver consistent readings with approximately ±1.6% accuracy, useful for diagnostic work and controlled charging.

• High/low side gauges showing PSI and BAR for clarity
• Multiple refrigerant scales printed on each dial for R134a, R410a, R22, and others
• Shock-resistant internals to preserve calibration under workshop conditions
• Accuracy suitable for routine service and troubleshooting

Which refrigerants and applications does the kit support?

This kit is compatible with a wide range of common refrigerants, including R134a, R410a, R22, R12, and R502, making it versatile for automotive AC, household HVAC maintenance, and light refrigeration tasks. The assortment of couplers, adapters, and color-coded hoses streamlines connection to various service ports.

• Supports R134a, R410a, R22, R12, R502 and similar refrigerants
• Includes 5 ft hoses and quick couplers for standard service ports
• Adapters expand compatibility with different fittings and systems
• Leak detector and oil included for more complete maintenance

How easy is this kit to use for someone new to AC work?

The kit is designed with beginner-friendly features like color-coded hoses and readable dials to simplify setup and interpretation. Clear labeling, included accessories, and a straightforward single-stage pump design reduce the learning curve for DIYers while still satisfying many professional needs.

• Color-coded low, high and service hoses for quick hookup
• Gauges with multiple refrigerant scales for easy reference
• Complete set of couplers, adapters, and oil reduces extra purchases
• Leak detector included to spot common service issues

Who is this for? This VIVOHOME vacuum pump and manifold gauge kit targets automotive enthusiasts, HVAC technicians, and competent DIYers who perform routine evacuation, leak testing, and refrigerant service on small- to medium-sized systems. If you need reliable vacuuming, clear pressure readings, and a broad set of service accessories in one portable package, this kit provides a balance of performance and convenience without requiring a large professional shop setup.
