The VIVOHOME 110V 1/4 HP single-stage vacuum pump is a compact, durable tool designed to evacuate air and moisture from small HVAC and refrigeration systems with a 3.5 CFM flow rate.

This pump pairs a corrosion-resistant die-cast aluminum housing with a high-torque copper motor to deliver dependable vacuum performance for home HVAC maintenance, automotive A/C work, and light refrigeration servicing. Built-in cooling features, visible oil monitoring, and safety filters simplify setup and reduce downtime. The package includes a 330 ml bottle of vacuum oil so you can start work immediately.

How quickly will this pump evacuate a small A/C or refrigeration system?

With a 1/4 HP single-stage motor the VIVOHOME pump provides up to 3.5 CFM of pumping capacity, which is suitable for small to moderate-sized systems. It is capable of drawing down to low pressures typical for system evacuation, helping remove trapped air and moisture prior to refrigerant charging.

• Flow rate: up to 3.5 cubic feet per minute (CFM)
• Motor: 1/4 HP single-stage for consistent vacuuming
• Ultimate vacuum level suitable for many residential and automotive jobs

What safety and reliability features protect the pump and your work area?

The pump includes multiple safeguards to prolong life and reduce risks during operation. An exhaust filter captures oil mist and reduces fumes, while a coarse inlet filter prevents dust and debris from entering the pump chamber. The design also uses anti-backflow protection to keep oil where it belongs.

• Exhaust port filter separates oil mist from gases for cleaner exhaust
• Coarse inlet filter keeps contaminants out of the pumping chamber
• Anti-backflow design prevents oil from returning to the system

How user-friendly is the VIVOHOME vacuum pump for DIYers and pros?

Controls and service points are laid out for fast checks and simple maintenance. An oil sight window with scale marks makes level checks quick, and a dedicated oil drain speeds draining and replacement. Ergonomic handle and shock-absorbing feet make transport and operation steadier and more comfortable.

• Oil sight window with level markings for accurate monitoring
• Oil drainage port for quick, clean oil changes
• Ergonomic carry handle and anti-slip feet for comfort and reduced vibration
