Orion Motor Tech AC Vacuum Pump and Gauge Set — 5 CFM Two-Stage, R1234yf/R134a Compatible

The Orion Motor Tech 5 CFM two-stage AC vacuum pump and gauge set is a complete, spark-safe service kit built to evacuate modern automotive and light HVAC systems for refrigerants including R1234yf, R134a, R32 and R410A.

This all-in-one kit combines a high-efficiency 5 CFM two-stage vacuum pump with a four-way manifold gauge, adapters, can taps, hoses, and vacuum oil so you can evacuate, diagnose and recharge air conditioning systems without hunting for additional tools. The pump’s two-stage design and 3450 rpm motor offer faster pull-downs to deep vacuum levels, while the included gauge and couplers let you take accurate pressure readings and make safe service connections for multiple refrigerant types.

How quickly and deeply does this pump evacuate an AC system?

The two-stage 5 CFM motor reaches down to around 1.5 microns (0.2 Pa) under ideal conditions, helping remove moisture and non-condensables faster than many single-stage units. That deeper pull-down shortens prep time before charging and improves the reliability of your service procedure.

• Rated 5 CFM pumping speed for faster evacuations
• Two-stage design for deeper vacuum levels
• 3450 rpm motor for consistent performance
• Typical pull-down to ~1.5 microns (0.2 Pa)

Is this pump safe to use with mildly flammable refrigerants like R1234yf?

The unit features an ignition-proof ON/OFF switch and sparkless design to reduce ignition risk while servicing A2L or mildly flammable refrigerants. While the pump is engineered to lower spark hazards, always follow refrigerant safety guidelines and local regulations when working with flammable blends.

• Sparkless construction and ignition-proof power switch
• Compatible service fittings for R1234yf and R134a
• Use with proper ventilation and safety procedures
• Complies with safe handling best practices for A2L refrigerants

What accessories are included and how do they help everyday service work?

The kit arrives with a full set of service components so you can start diagnosing and evacuating systems immediately. Included adapters, self-sealing can taps and quick couplers eliminate the need for aftermarket parts and streamline transitions between refrigerant types.

• Four-way manifold gauge for accurate system readings
• R134a & R1234yf self-sealing can taps for safe topping and transfer
• R134a quick couplers and R134a→R1234yf adapters for compatibility
• Vacuum oil and four service hoses for complete setup

How user-friendly is the pump in terms of noise, oil handling, and maintenance?

Orion Motor Tech designed this pump to minimize oil mist and operate at comfortable noise levels for workshop environments. A combined oil fill/exhaust port with an oil-mist-free cap keeps work areas cleaner and the sound level stays at or below 70 dB for less fatigue during longer jobs.

• Oil-mist-free cap reduces contamination and cleanup
• Runs at or below 70 dB for quieter operation
• Clear gauge dial with calibration adjustment for precise readings
• Durable construction for routine shop use

Who is this for: Technicians, mobile mechanics and DIYers who service automotive or light commercial HVAC systems and need a portable, complete evacuation and diagnostic solution that supports modern refrigerants. It’s useful for shops that work on a mix of R134a and newer refrigerants like R1234yf, as well as installers who require fast pull-down times and accurate pressure measurement without sourcing separate adapters and taps.
