VIVOHOME 1/3 HP 4 CFM Vacuum Pump & R134a Manifold Gauge Set — Single-Stage, Portable HVAC Kit with 3 Hoses

The VIVOHOME 1/3 HP 4 CFM single-stage vacuum pump and R134a manifold gauge set is a complete, portable HVAC service kit built to evacuate systems quickly and read pressures accurately for automotive and light residential air conditioning work.

This all-in-one kit pairs a 4 CFM rotary vane vacuum pump with a durable three-valve manifold, three reinforced hoses, adapter fittings and accessories so you can pull deep vacuums, check refrigerant flow, and top off R134a systems. The pump’s die-cast aluminum housing, clear oil sight glass and bottom drain port simplify maintenance, while the color-coded hoses and shock-resistant gauge cores keep everyday service organized and reliable. The set is designed to serve both do-it-yourselfers and technicians handling small split, window and vehicle A/C units.

How fast and deep can this pump evacuate an A/C system?

The 4 CFM single-stage rotary vane design provides strong suction for rapid evacuation of moisture and non-condensables from small to medium systems. It’s intended for automotive A/C and 1–3 HP residential split or window units where a single-stage pump is appropriate.

• Rated 4 cubic feet per minute for faster pull-downs
• Single-stage pump suitable for typical automotive and light home HVAC work
• Built-in cooling fan for extended use without overheating

What features make maintenance and oil handling easy?

VIVOHOME designed the pump with practical serviceability in mind: a clear oil sight glass lets you check oil level at a glance, and the bottom drain port enables clean, simple oil changes. The package includes 0.35 qt (330 ml) of pump oil to get started.

• Transparent sight glass for quick oil inspection
• Bottom drain port reduces spills during oil replacement
• Included pump oil lets you start working immediately

Are the gauges and hoses accurate and durable for field use?

The manifold features large, easy-to-read gauges with shock-resistant cores to preserve accuracy while on the job. Three 5-foot reinforced hoses (red, blue, yellow) provide flexible, leak-resistant connections and the kit includes adapters for common refrigerants.

• High-visibility gauge faces with protective cores
• 5 ft reinforced color-coded hoses for high, low, and service lines
• Adapters and quick couplers for R134a, R12, R22, R502, and R410a compatibility

What accessories are included, and how portable is the set?

The kit bundles all essential items into a compact carry bag for transport and storage, making it convenient for roadside work or household maintenance. Included accessories let you perform leak checks, attach cans, and connect to multiple refrigerant types without hunting for extra parts.

• Manifold gauge set, vacuum pump, three hoses, and adapters
• Leak detector, R134a can tap, quick couplers, and R410a adapter
• Sturdy carry bag and ergonomic pump handle for portability

Who is this for: homeowners who maintain window or portable air conditioners, DIY vehicle owners servicing R134a systems, and HVAC technicians needing a lightweight, entry-to-mid-level vacuum and charging kit. It’s best suited to jobs where a single-stage 4 CFM pump provides sufficient evacuation and where on-site portability and easy maintenance are priorities. Avoid using this kit for large commercial systems that require high-capacity or two-stage vacuum equipment.
