Orion Motor Tech 3.5 CFM AC Vacuum Pump & Gauge Set — A2L R1234yf Ready, 15 Micron

Orion Motor Tech's OMT 3.5 CFM A2L AC Vacuum Pump and Gauge Set is a complete evacuation and diagnostic kit designed to safely service R1234yf, R32, R134a and R410A systems with fast pull-down and spark-reduced operation.

This professional-grade kit brings together a compact 1/4 hp vacuum pump, a precise 3-way manifold gauge, self-sealing can taps, adapters, vacuum oil and three service hoses so you can evacuate, test and charge vehicle and small HVAC systems. The pump is optimized for modern mildly flammable refrigerants (A2L) and common auto refrigerants, delivering efficient performance while keeping oil mist and noise to a minimum.

How quickly will this pump evacuate an air conditioning system?

The pump runs at 1720 rpm and produces 3.5 cubic feet per minute (CFM), allowing rapid removal of moisture and air. In typical auto and small HVAC jobs it pulls down to deep vacuum levels to speed up repairs and reduce downtime.

• 3.5 CFM continuous airflow for faster evacuation
• 1720 rpm motor for steady performance
• Capable of reaching 15 microns (≈2 Pa) for thorough system evacuation

Is this set safe for use with A2L or mildly flammable refrigerants?

The pump includes a spark-resistant design and an ignition-proof ON/OFF switch to reduce ignition risk while working with A2L refrigerants. Follow refrigerant-specific safety practices and local regulations when servicing systems.

• Sparkless operation to lower ignition potential
• Ignition-proof on/off switch for safer handling of mildly flammable refrigerants
• Includes adapters and self-sealing taps to minimize refrigerant loss

What diagnostic and connection accessories are included in the kit?

This all-in-one service set equips you with a 3-way manifold gauge for accurate pressure checks, self-sealing can taps for R134a and R1234yf, quick couplers, adapters for cross-compatibility and three durable hoses to complete most common service tasks.

• 3-way manifold gauge with clear dial and calibration adjustment
• R134a and R1234yf self-sealing can taps and R134a-to-R1234yf adapters
• R134a quick couplers, three service hoses and vacuum oil included

How does the pump handle oil mist and noise in a workshop environment?

The unit uses an oil mist reducer at the combined oil fill/exhaust port and runs at or below 70 dB to create a cleaner, quieter workspace. That keeps the surrounding area neater and reduces distraction during extended use.

• Oil mist-free cap reduces airborne lubricant and cleanup
• Combined oil fill/exhaust port for easier maintenance
• Noise level designed at or under 70 dB for comfortable operation

Who is this for? This Orion Motor Tech pump and gauge set is built for automotive technicians, mobile service professionals, HVAC hobbyists and workshops that need a portable, compatible evacuation solution for modern refrigerants. It suits users who require rapid pull-down to low microns, convenient manifold diagnostics and the connectors necessary to service R1234yf, R32, R134a and R410A systems. If you prioritize safety features for mildly flammable refrigerants, lower oil mist, and a quieter work environment, this kit provides a practical, ready-to-use option.
