VIVOHOME 1/4 HP 3.5 CFM Vacuum Pump with R134a Manifold Gauge Set — Single-Stage, Portable Kit with Hoses & Carrying Bag

The VIVOHOME 1/4 HP 3.5 CFM single-stage vacuum pump and R134a manifold gauge set is a portable diagnostic and evacuation kit built to remove air and moisture from automotive and small HVAC systems before refrigerant charging.

This compact kit combines a lightweight die-cast aluminum vacuum pump with an included manifold gauge set, hoses, thermometer and vacuum oil so you can perform routine AC maintenance, system evacuation, and pressure checks at home or in a workshop. The package balances a small footprint and ergonomic handling with the practical features technicians expect: visible oil monitoring, color-coded service hoses, R410a adapters, and a carrying bag for the gauges.

How does the pump evacuate air and moisture from my AC system?

The single-stage 1/4 HP motor generates up to 3.5 CFM to draw down system pressure, removing trapped air and moisture that can impair refrigerant performance. An oil-filled vane design uses the included vacuum oil for sealing and lubrication; an oil sight glass and drain valve make maintenance straightforward.

• 3.5 CFM flow rate suitable for automotive and small HVAC systems
• Oil sight glass for quick oil-condition checks
• Bottom oil drain valve for fast, clean oil changes
• Includes 0.35 qt (330 ml) bottle of vacuum oil

What measurements and readings can the manifold gauge set provide?

The color-coded manifold gauges give clear high- and low-side pressure readings for common refrigerants including R134a, R12, R22, R502 and R410a. Large viewing windows and precision dials help you diagnose leaks, measure evacuation progress, and confirm system pressures before charging refrigerant.

• Separate red (high) and blue (low) gauges for intuitive reading
• Included thermometer for temperature checks during service
• R410a adapters provided for compatibility with modern systems
• Carrying bag keeps gauges organized and protected

Is the kit easy to carry and use for a DIYer or technician?

The pump’s die-cast aluminum housing and ergonomic grip keep weight down while remaining durable for field use. A high-volume cooling fan supports extended operation, and the anti-slip rubber base stabilizes the unit during use. Color-coded flexible hoses and simple connector fittings reduce setup time and help avoid mistakes.

• Ergonomic handle and lightweight chassis for portability
• Composite anti-slip rubber base prevents movement
• Durable, leak-resistant red/blue/yellow hoses for faster hookups
• High-volume cooling fan for longer run times

Who is this for? This VIVOHOME kit is aimed at automotive enthusiasts, HVAC apprentices, small-shop technicians and DIYers who need a compact, cost-conscious vacuum pump combined with a functional manifold gauge set. It’s particularly useful for routine AC servicing, system evacuation prior to refrigerant charging, and basic pressure diagnostics on passenger vehicles, light-duty refrigeration, and small HVAC units. If you require industrial-scale evacuation or advanced recovery features, consider a higher-capacity or two-stage unit; otherwise this set offers a practical balance of portability, compatibility and the accessories needed to get common evacuations and pressure checks done quickly.
