VIVOHOME 3.5 CFM 1/4 HP HVAC Vacuum Pump – 110V, R134a/R12/R22/R502/R410a, Auto AC Vacuum Pump with Oil Bottle

VIVOHOME HVAC Vacuum Pump: premium build, dependable performance

The VIVOHOME 3.5 CFM HVAC Vacuum Pump combines a robust 1/4 HP single‑stage motor with a durable die‑cast aluminum housing. It pulls a deep vacuum (up to 5 Pa) to help prepare air conditioning systems by removing moisture before refrigerant refill. Built for frequent use, it emphasizes steady operation and long service life, making it a practical choice for DIY enthusiasts and pros alike.

Key benefits that matter in the shop or garage

• Strong, efficient performance: 3.5 CFM airflow with a compact, reliable single‑stage design for fast moisture removal.
• Smart cooling design: mesh vents, T-shaped motor heat fins, and a powerful cooling fan keep the copper motor temp in check for smoother, longer runs.
• Safe, clean operation: an exhaust filter separates oil mist, a coarse inlet filter guards the pump chamber, and an anti‑backflow design protects the oil and equipment.
• Easy maintenance: a clear oil sight window with scale marks lets you monitor oil level at a glance; the oil drain port simplifies servicing, and a 0.35 quart / 330 ml vacuum oil bottle is included for convenience.
• Ergonomic and portable: an ergonomic grip handle and anti‑slip, vibration‑reducing base make it comfortable to use and move between jobs.
• Broad compatibility: works with R134a, R12, R22, and R502; with a 5/16‑inch adapter it can also handle R410a, expanding its versatility.

Real‑world uses and practical scenarios

• Ideal for household AC servicing and small automotive air‑conditioning tasks, helping prep systems before refilling refrigerant.
• Suitable for refrigeration work, resin degassing, and other small repair tasks that require a strong vacuum pull from a compact tool.
• Works well in shops or on the go thanks to a compact footprint and straightforward operation.

What’s inside and how to use

The package includes a bottle of vacuum oil to get you started and a straightforward design that simplifies setup and operation. To use, connect the appropriate refrigerant line, switch on, allow the pump to pull a deep vacuum, and then refill with refrigerant as needed. Always follow local guidelines and safety practices when servicing systems.

Compatibility and care tips

• Compatible refrigerants: R134a, R12, R22, R502; R410a via 5/16‑inch adapter.
• Monitor oil levels using the sight window; drain and refill as part of routine maintenance to keep performance steady.
