VIVOHOME 4 CFM Vacuum Pump & R134a Manifold Gauge Kit — 1/3 HP with Leak Detector and Carry Bag

VIVOHOME’s 4 CFM single-stage rotary vane vacuum pump and R134a manifold gauge kit is a complete HVAC service set designed to evacuate, test, and recharge automotive and residential air-conditioning systems.

This all-in-one kit pairs a 1/3 HP, 4 CFM rotary vane vacuum pump with a durable manifold gauge set, reinforced hoses, leak detector, adapters and accessories stored in a zippered carry bag. The pump’s die-cast aluminum housing, clear oil sight glass and cooling fan are built for extended jobs, while the gauge set and color-coded hoses support fast, accurate pressure readings and refrigerant handling for R134a and other common refrigerants.

How quickly and deeply will the pump evacuate an AC system?

The single-stage 4 CFM rotary vane pump is engineered for efficient evacuation of small-to-medium systems—automotive A/C, split systems, window and portable units. It pulls down moisture and non-condensables faster than lower-capacity units, helping prepare the system for refrigerant charging.

• 4 CFM flow rate for timely evacuation
• Single-stage rotary vane design suitable for common HVAC tasks
• Clear oil sight glass for monitoring pump performance
• Bottom drain port for clean oil changes

What gauges, hoses and adapters are included and how accurate are they?

The kit includes a heavy-duty manifold gauge set with large viewing glass and shock-resistant internals to maintain accuracy in the field. Three color-coded 5 ft reinforced hoses (red, blue, yellow) plus R410A adapters, R134a can taps and quick couplers cover most service scenarios.

• High- and low-side manifold gauges with clear readouts
• Three 5 ft reinforced hoses for flexible, leak-resistant connections
• 1/4"–to–5/16" adapter for R410A compatibility and multiple can taps for R134a
• Shock-resistant gauge cores for consistent readings during transport

How is oil management, cooling and continuous use handled?

VIVOHOME built the pump with a high-volume cooling fan and a bottom drain port to support longer operating periods and easier maintenance. The included 0.35 qt (330 ml) pump oil and the sight glass let you check and change oil without guesswork, reducing downtime and mess.

• Integrated cooling fan for sustained operation
• Oil sight glass for quick visual checks
• Bottom drain port for cleaner, simpler oil changes
• Supplied 0.35 qt/330 ml pump oil for immediate use

Which systems and users is this kit compatible with?

The set is intended for service on automotive A/C, residential HVAC, heat pumps and portable or window air conditioners rated roughly 1–3 HP. It supports common refrigerants including R134a, R12, R22, R502 and, with adapter, R410A—suitable for DIYers and professionals who need portability and a ready-to-use toolkit.

• Ideal for automotive A/C and household HVAC maintenance
• Adapters and can taps included for multiple refrigerant types
• Lightweight pump with ergonomic handle for portability
• Carry bag keeps components organized for on-site work

Who is this for: This VIVOHOME kit suits DIY enthusiasts, mobile technicians and small-shop HVAC pros who want a compact, reliable evacuation and service package. If you perform routine refrigerant recovery, evacuation, leak detection and charging on vehicles or residential systems, this set supplies the essential tools—just follow refrigerant safety rules, local regulations and refrigerant-specific handling procedures.
