VIVOHOME 1/4 HP 3.5 CFM Vacuum Pump & R134a Manifold Gauge Set — Single-Stage, Dual-Scale Kit

The VIVOHOME 1/4 HP 3.5 CFM single-stage vacuum pump and R134a manifold gauge set is a complete automotive A/C service kit built for evacuating, testing, and charging R134a, R12 and R22 systems.

This all-in-one kit combines a stable rotary-vane vacuum pump with a practical dual-scale manifold gauge set and color-coded hoses so you can diagnose, evacuate, and service vehicle A/C lines with confidence. The compact pump features a 1/4 HP motor that moves 3.5 cubic feet per minute and draws down to low pressures, while the manifold offers ±1.6% accuracy and convenient controls for routine maintenance and basic repair tasks. Included adapters, quick couplers and vacuum oil let you begin work right away.

How does this pump perform during evacuation and leak testing?

The single-stage rotary vane design delivers steady airflow and strong vacuum for typical automotive A/C jobs. It pulls systems down to near 5 Pa under the right conditions and maintains a continuous flow rate of 3.5 CFM for effective moisture and air removal.

• 1/4 HP motor for consistent rotary-vane operation
• 3.5 CFM flow rate ideal for small- to medium-size systems
• Capable of pulling down to approximately 5 Pa for reliable evacuation
• Anti-backflow valve reduces risk of oil return at shutdown

What safety and maintenance features prevent contamination and extend service life?

Built-in filtration and easy-access maintenance points help keep the pump clean and reduce wear. A stainless steel intake filter blocks debris, and a cotton exhaust filter manages oil mist and noise. The clear oil sight and bottom drain valve make oil checks and changes fast and mess-free.

• Internal stainless steel intake filter to stop particulates
• Cotton exhaust filter minimizes oil aerosol and reduces noise
• Clear sight window for quick oil level checks
• Bottom drain valve for straightforward oil changes

How accurate and user-friendly is the included manifold gauge set?

The manifold gauge is designed for practical diagnostics with dual-unit scales and a ±1.6% accuracy spec for repeatable readings. Rubber protective covers, large sight glasses and a hanging hook make field use simpler, while R134a quick couplers and color-coded hoses speed up connections and reduce mistakes.

• Dual-scale gauges with ±1.6% accuracy for dependable readings
• Shock-resistant core and rubber covers for workshop durability
• Three 3000 PSI color-coded hoses and quick couplers included
• Built-in hanging hook for easy placement during service

What accessories come with the kit and what refrigerants is it for?

This kit ships ready for immediate use with adapters and vacuum oil so you can begin evacuation and basic service without sourcing extras. It is designed for R134a, R12 and R22 automotive systems and is not compatible with R410A; always confirm the refrigerant type before proceeding.

• Includes pump, manifold gauge, three hoses, and quick couplers
• 1/4" M to 1/2" F adapter and R134a self-sealing can tap included
• Comes with 0.35 qt vacuum oil for initial pump filling
• Not compatible with R410A systems — verify refrigerant first

Who is this for: The VIVOHOME 1/4 HP 3.5 CFM vacuum pump and gauge set is aimed at mechanics, mobile technicians, and experienced DIYers who service vehicle A/C systems. It suits garage environments and field work where a portable, easy-to-maintain evacuation solution and a reliable manifold gauge are needed for routine diagnostics, evacuation, and charging tasks. This kit balances performance, portability, and convenience for standard automotive refrigerants.
