VIVOHOME 1/4 HP Rotary Vane Vacuum Pump 110V 3.5 CFM — 5 Pa Ultimate, Dual Fittings

The VIVOHOME 110V 1/4 HP single-stage rotary vane vacuum pump quickly evacuates air and moisture from automotive and household AC systems with a 3.5 CFM flow and a fast 5 Pa ultimate vacuum.

Compact yet powerful, this VIVOHOME vacuum pump is built for service technicians, HVAC hobbyists, and DIYers who need dependable evacuation of refrigerant lines before a recharge. Its 1/4 HP motor and rotary vane design deliver steady airflow while protective features and durable materials keep the unit reliable across repeated jobs. The pump balances performance, portability, and user-friendly maintenance points like a visible oil window and bottom drain.

How fast and effective is the pump at creating a vacuum?

The pump generates a 3.5 CFM flow rate and typically reaches an ultimate vacuum of 5 Pa in about 3 minutes under normal conditions. That speed helps remove air and moisture quickly so you can proceed to leak tests or refrigerant charging without long wait times.

• 1/4 HP (180W) motor running at 1440 r/min for consistent performance
• 3.5 CFM rated flow for efficient evacuation of lines and components
• 5 Pa ultimate vacuum achieved rapidly—suitable for most AC servicing tasks

Which refrigerants and connections does it support?

This VIVOHOME pump works with common refrigerants including R134a, R12, R22 and R502; R410a can also be used when a 5/16-inch adapter (not included) is fitted. It offers both 1/4-inch SAE and 1/2-inch Acme intake fittings to match a wide range of manifold hose setups and service ports.

• Compatible natively with R134a, R12, R22, R502
• R410a usable with a 5/16-inch adapter (adapter not included)
• Dual intake fittings: 1/4-inch SAE and 1/2-inch Acme for flexible hookups

What safety and durability features protect the pump?

The pump is engineered for longevity with a one-piece die-cast aluminum housing and a four-pole pure copper motor that tolerates everyday jobsite wear. It incorporates motor current protection to reduce risk from overload or phase loss, plus multiple filtration layers to keep the internal chamber and exhaust clean.

• Die-cast aluminum body resists impact while remaining lightweight
• Motor current protection guards against overload and phase loss
• 304 stainless steel coarse intake filter and cotton exhaust filter capture contaminants and oil mist

How easy is it to operate and maintain on the job?

Designed for practical use, the pump includes an ergonomic handle, an easy ON/OFF switch, and a clear oil sight window so you can check fluid levels at a glance. Routine oil changes are simplified by the bottom drain valve, and the low-noise design with a cooling fan and non-slip base improves comfort during longer service sessions.

• Visible oil window and simple oil fill port for quick monitoring
• Bottom oil drain valve speeds maintenance and reduces mess
• Approximately 65 dB operation with built-in cooling fan and non-slip feet

Who is this for? The VIVOHOME 110V 1/4 HP 3.5 CFM single-stage rotary vane vacuum pump is suitable for HVAC technicians, automotive air-conditioning repairers, and skilled DIYers needing a portable, robust evacuation tool. It pairs well with standard manifold gauges and hose sets, and its combination of protective features and multiple fittings makes it a practical choice when you require fast, repeatable vacuum performance without oversized industrial equipment.
