VIVOHOME 110V 1/4 HP Rotary Vane Vacuum Pump with Oil Bottle – 3.5 CFM, 5 Pa

Reliable, portable vacuum pump for AC maintenance

The VIVOHOME 110V vacuum pump blends compact design with solid performance to support professional and DIY refrigerant work. Driven by a 1/4 HP motor running at 1440 r/min, it delivers a steady 3.5 CFM flow and achieves a deep vacuum of 5 Pa in minutes. This combination helps you prep systems for refrigerant recharge with confidence, while the integrated motor current protection adds a layer of safety during extended sessions.

Designed for real-world use, the pump balances power with portability. The lightweight, one-piece die-cast aluminum housing withstands handling in busy shop environments or on-site service calls. A built-in cooling fan helps maintain stable operation, and the low-noise performance (approximately 65 dB) keeps the workspace comfortable even during longer sessions.

Smart compatibility and flexible connections

Versatility matters in the field. This pump supports multiple refrigerants, including R134a, R12, R22, and R502. When paired with a 5/16-inch adapter (not included), it can be used with R410a. Connection options include both 1/4-inch SAE and 1/2-inch Acme intake fittings, giving you flexible options for various AC systems without swapping equipment.

Durable, easy-to-maintain design

Maintenance is straightforward thanks to a 304 stainless steel coarse filter that protects the pump chamber, and a cotton layer filter at the exhaust that helps capture oil mist and impurities. The combination supports cleaner operation and helps extend the life of the pump in everyday service.

Everyday usability is a focus: an ergonomic grip handle, a simple ON/OFF switch, and a clear oil viewing window make oil checks and top-ups quick. The bottom oil drain valve simplifies changes, while the overall design emphasizes stability and ease of transport between job sites.
