VIVOHOME 1.5 HP Dual-Stage HVAC Vacuum Pump 14.4 CFM — 110V, Visible Oil Window & Included Oil Bottles

The VIVOHOME 110V 1.5 HP dual-stage HVAC vacuum pump delivers up to 14.4 CFM flow and professional evacuation capability for refrigeration and HVAC service tasks.

This compact, heavy-duty pump combines a dual-stage motor, visible oil window, and included vacuum oil bottles to offer reliable evacuation of air-conditioning and refrigeration systems. Built with a stamped aluminum alloy body, vibration-damping base and a gas-ballast valve, it targets technicians and skilled DIYers who need fast, stable pull-down performance and straightforward maintenance features.

How fast and deep can this pump evacuate an HVAC system?

The 1.5 HP dual-stage motor provides strong suction and steady two-stage pumping action for improved depth and speed compared with single-stage units. It reaches a maximum flow rating of 14.4 CFM and is designed to pull systems down to low pressure levels suitable for typical service work.

• Dual-stage design enhances final vacuum level and evacuation efficiency
• Rated flow up to 14.4 cubic feet per minute (CFM)
• Capable of drawing systems to low absolute pressures for servicing

What safety and contamination protections does it include?

Controls and filtration are arranged to reduce oil loss and keep debris out of the pump internals. An exhaust filter captures oil mist while the inlet uses a coarse screen to block larger particles. Anti-backflow features and thermal protection help prevent damage and reduce the risk of contamination during operation.

• Exhaust oil-mist filter minimizes airborne oil and keeps workspace cleaner
• Inlet coarse filter prevents dust from entering the pump chamber
• Built-in overheat protection and anti-backflow design for safer runs

How is this pump designed for user convenience and maintenance?

The unit emphasizes practical handling and easy service: a comfortable grip handle, a clear oil sight window with scale markings, and a bottom drain valve make oil checks and changes quick. Two 0.35 qt (330 ml) bottles of compatible vacuum oil are included so you can start work without sourcing fluids separately.

• Visible oil window with measurement marks for fast level checks
• Ergonomic carrying handle and non-slip base for stable positioning
• Bottom oil drain valve for thorough and clean oil removal

Which fittings and refrigerants is this pump compatible with?

Multiple inlet port sizes and broad refrigerant compatibility make this pump flexible for commercial and residential jobs. It supports common service fittings and several refrigerant types used in modern and legacy systems.

• Inlet ports: 1/4" SAE, 1/2" ACME, and 3/8" SAE to match common hoses and adapters
• Suitable for R12, R22, R134a, R410a, R404, and R502 service tasks
• Handy for refrigeration maintenance, HVAC repair, vacuum packaging, and related industrial use

Who is this for? The VIVOHOME 110V 1.5 HP dual-stage vacuum pump is intended for HVAC technicians, refrigeration service professionals, and experienced DIY installers who need a portable, powerful evacuation tool with practical maintenance features. It's also a strong option for small commercial shops that require a versatile pump able to handle a variety of fittings and refrigerants while minimizing oil contamination and downtime.
