Overview

The VIVOHOME 4.5 CFM HVAC vacuum pump is designed to speed up refrigerant evacuation and prepare air conditioning systems for service. Its compact, one piece die cast aluminum housing pairs with a robust four pole copper motor to deliver steady, dependable performance on the job. Built for durability and ease of maintenance, it supports technicians who value reliable tools in the field.

Fast evacuation you can rely on

A 1/3 HP (250 W) motor runs at 1728 rpm, delivering 4.5 CFM of airflow and achieving an ultimate vacuum around 5 Pa in roughly three minutes. This rapid pull helps move from diagnosis to recharge with efficiency, reducing downtime between steps.

• 4.5 CFM rated performance for quick evacuation
• Approximately 3 minutes to reach a 5 Pa ultimate vacuum
• Standard 1/4 in SAE inlet supports a wide range of service hoses
• 110 V power is suitable for typical shop outlets

Extensive refrigerant compatibility

The pump is designed to support common refrigerants used in automotive and home AC systems, including R134a, R12, R22, and R502. For R410a operations, a 5/16 inch adapter is required (not included). This broad compatibility helps you cover more jobs with a single tool.

Durable, portable build

The one piece die cast aluminum housing and a four pole copper motor resist wear and drops, delivering a rugged tool you can carry between service calls. The compact form makes it easier to maneuver in tight spaces and crowded engine bays.

Safety focused design

Key safeguards include motor current protection to prevent overload or phase loss, plus a 304 stainless steel coarse inlet filter to protect the pump chamber from contaminants. An exhaust cotton layer traps debris and oil mist for cleaner operation over time.

Quiet, stable operation

Designed for professional servicing, it operates around 65 dB with an integrated cooling fan and a non slip base, delivering steady performance without interrupting nearby work.

Maintenance made simple

Ergonomic handle, straightforward ON/OFF switch, a clear oil sight window, and a bottom drain valve simplify oil checks and changes. The included oil bottle supports convenient maintenance and minimizes spills and guesswork.

Practical field scenarios

In everyday HVAC service, you may use this pump for rapid evacuations before recharge, system testing, and resin degassing workflows where applicable. The design caters to mobile techs and shop environments alike, offering dependable operation when you need it.
