VIVOHOME Vacuum Pump and Manifold Gauge Set — 1/4 HP 3.5 CFM R134a Kit with Hoses & Oil

The VIVOHOME 1/4 HP 3.5 CFM single-stage vacuum pump and R134a manifold gauge set is a ready-to-use kit that pulls down A/C systems, measures pressures accurately, and includes hoses, couplers, and oil for routine automotive refrigeration service.

This compact, portable kit pairs a 1/4 HP rotary vane vacuum pump with a three-valve manifold gauge designed for R134a/R12/R22 automotive systems. Built to handle common garage and DIY A/C maintenance, the pump delivers a steady 3.5 CFM flow and reaches deep vacuum levels while the manifold provides clear dual-unit readings and durable protection for repeated diagnostics.

How does this pump remove air and moisture from automotive A/C systems?

The single-stage rotary vane pump evacuates lines and components by drawing down pressure to remove trapped air and moisture that can impair refrigeration performance. It includes internal and exhaust filters, plus an anti-backflow valve to protect the unit during shutdown.

• 3.5 CFM flow rate for faster evacuation compared with smaller pumps
• Pulls to about 5 Pa for effective moisture removal in typical service tasks
• Stainless-steel intake filter keeps debris out of the pump internals
• Cotton exhaust filter reduces oil mist and dampens noise

What instruments and accessories are included for charging and diagnostics?

The kit arrives with a three-port manifold gauge, three color-coded 3000 PSI hoses, R134a quick couplers, adapters, and a bottle of vacuum oil—allowing immediate setup for most automotive systems (excluding R410A). The manifold offers ±1.6% accuracy and a shock-resistant core to withstand workshop use.

• Dual-scale manifold with large sight glasses and built-in hanging hook
• 3 color-coded high-pressure hoses for clear connections and safety
• R134a self-sealing can tap and 1/4"M to 1/2"F adapter for common fittings
• 0.35 qt vacuum oil included for proper pump lubrication and performance

How portable and serviceable is the VIVOHOME vacuum pump?

Designed for mobility, the pump uses a one-piece aluminum housing with an ergonomic handle and non-slip rubber feet for stable operation. Routine checks and oil changes are simplified with a clear sight window and a bottom drain valve for fast maintenance between jobs.

• Lightweight aluminum body and molded handle for easy transport
• Clear oil sight window for quick level verification
• Bottom drain valve speeds oil changes and reduces downtime
• Anti-backflow valve to protect the pump during shutdown cycles

Which refrigerants and applications is this kit suitable for?

This set supports common automotive refrigerants R134a, R12, and R22 and is intended for vehicle A/C servicing, repairs, and DIY maintenance tasks. It is not compatible with R410A systems—confirm the refrigerant type before use to avoid damage or improper charging.

• Recommended for R134a, R12, and R22 automotive systems
• Not compatible with R410A—check system refrigerant first
• Ideal for garage shops, mobile technicians, and home mechanics
• Kit provides immediate functionality for common service procedures

Who is this for: Automotive technicians, hobbyist mechanics, and mobile service providers who need a compact, reliable vacuum pump and manifold kit for routine A/C evacuation and basic diagnostics. If you work on passenger vehicles using R134a/R12/R22, want a portable unit with easy maintenance features, and prefer an all-in-one set that includes hoses, couplers, and oil for immediate use, this VIVOHOME kit is built to meet those needs. Confirm refrigerant compatibility before purchase and follow local regulations for refrigerant handling and disposal.
