VIVOHOME 3/4 HP HVAC Vacuum Pump 110V — Dual-Stage Rotary Vane, 7.2 CFM, 15 Micron

The VIVOHOME 110V 3/4 HP dual-stage rotary vane vacuum pump delivers 7.2 CFM flow and deep evacuation down to 15 microns for HVAC and refrigeration service.

This compact, workshop-ready pump combines a high-torque copper motor, dual-stage vacuuming, and user-friendly features to speed system evacuation and simplify maintenance. Built with a die-cast aluminum housing, visible oil window, inlet/exhaust fittings, and included vacuum oil bottles, it’s designed for technicians who need dependable pull-down performance without a heavy industrial footprint.

How quickly and deeply does this pump evacuate HVAC systems?

The dual-stage rotary vane design plus a 3/4 HP motor generates a 7.2 CFM flow rate and can pull a system down to about 15 microns (0.2 Pa), enabling fast, thorough moisture and air removal. This level of vacuum is appropriate for most residential and light commercial refrigeration and air-conditioning service tasks.

• Dual-stage vacuum for deeper pull-down and cleaner evacuation.
• 7.2 CFM flow for quicker evacuation cycles on typical systems.
• Achieves approximately 15 microns (0.2 Pa) for effective moisture removal.

What safety and durability features protect this pump in daily use?

The pump includes thermal motor protection that shuts the unit down under overheating conditions and a large cooling fan with mesh vents for efficient heat dissipation. Die-cast aluminum housing, a cold-rolled iron base, rubber feet, and an ergonomic handle reduce vibration and protect internal components for long service life.

• Thermal protection prevents motor damage from overheating.
• High-volume cooling fan and mesh vents for steady temperature control.
• Sturdy construction and rubber feet minimize vibration and noise.

Which fittings, fluids, and system types are supported by this model?

The pump ships with common inlet fittings (1/4" SAE, 1/2" ACME, 3/8" SAE) and two bottles of vacuum oil (330 mL + 230 mL), so you can begin service work immediately. It’s intended for use with many refrigerants such as R12, R22, R134a, and R410a, but is not suitable for R32 or 1234yf.

• Included fittings cover standard refrigeration service connections.
• Two vacuum oil bottles provided for immediate operation and refill.
• Compatible with common refrigerants (not for R32 or 1234yf).

How straightforward is routine operation and maintenance?

Operation is designed to be intuitive: easy-connect inlet/exhaust fittings, a visible oil sight glass with scale marks, a bottom drain valve for fast oil changes, and an exhaust oil mist filter for cleaner output. These features reduce downtime and simplify checks between jobs.

• Visible oil window with scale marks for accurate monitoring.
• Bottom drain valve speeds oil changes and routine service.
• Exhaust filter traps oil mist for cleaner workplace air and pump performance.

Who is this for: HVAC and refrigeration technicians, automotive A/C specialists, and small commercial maintenance teams who need a portable yet powerful vacuum pump for evacuation, dehydration, and refrigerant charging tasks. It suits users who want professional-grade pull-down capability, safety features, and included accessories in a compact 110V package.
