Orion Motor Tech 5 CFM Sparkless HVAC Vacuum Pump — A2L Safe for R1234yf/R32, 1.5 Micron Pull-Down

The OMT 5 CFM A2L sparkless vacuum pump is a compact, ignition-proof evacuation tool built to safely pull systems down to 1.5 microns while handling mildly flammable refrigerants like R1234yf and R32.

Designed for HVAC technicians and advanced DIYers, this Orion Motor Tech pump combines sparkless switching, efficient 5 CFM flow, and oil-mist reduction to make evacuations faster, cleaner, and quieter. It’s engineered to meet the demands of modern refrigerants while remaining portable and easy to use on vehicles, commercial lines, and shop systems.

How does this pump keep work safer with A2L refrigerants?

The unit uses an ignition-proof ON/OFF switch and sparkless design so the electrical controls minimize ignition risk when working with mildly flammable refrigerants. Combined with a sealed oil fill/exhaust port and an oil-mist cap, it reduces potential ignition sources and airborne oil aerosols.

• Ignition-proof ON/OFF switch for sparkless starts and stops
• Sealed combined oil fill/exhaust port with mist-reducing cap
• Reduces oil spray with a double-layer baffle inside the reservoir

What evacuation performance can I expect on R1234yf, R32, or R134a systems?

Powered by a 3450 rpm motor, the pump provides a 5 CFM displacement rate and is capable of pulling down systems to approximately 1.5 microns (0.2 Pa). That speed helps shorten evacuation time on most automotive and light commercial circuits so you can move through jobs efficiently.

• 5 CFM pumping capacity for faster evacuations
• Rated pull-down to about 1.5 microns (0.2 Pa)
• 3450 rpm motor optimized for steady, reliable flow

How does the design reduce maintenance, mess, and noise?

The pump’s 14.9 fl. oz. oil tank and angled drain allow longer run times and simpler oil changes. A reinforced base and double-layer internal baffle lower oil carryover, and the oil-mist-free cap reduces airborne droplets. Noise is held at or below about 70 dB for a more comfortable work environment.

• 14.9 fl. oz. reservoir reduces refill frequency
• Angled drain and reinforced bottom for easy, tidy oil removal
• Quiet operation at or under 70 dB for shop comfort

Will this pump fit my tools and applications?

The OMT pump accepts common HVAC fittings so it integrates with a wide range of manifolds, hoses, and adapters. Its compact footprint and ergonomic handle make it suitable for mobile service calls, shop benches, and lab tables where space and transportability matter.

• Compatible with 1/4" SAE and 1/2" ACME fittings
• Compact housing and carrying handle for portability
• Versatile for HVAC, automotive A/C, lab, and packaging use

Who is this for? Technicians and serious DIYers who work with modern refrigerants and need a balance of safety, performance, and portability will value this Orion Motor Tech pump. It’s especially useful for automotive A/C service and light commercial HVAC work where A2L compatibility, quick pull-down, reduced oil mist, and quiet operation matter. If you require a sparkless, efficient evacuation solution that integrates with standard tools and minimizes downtime, this model is built to meet those needs.
