Orion Motor Tech VPH-C141-A0 Two-Stage Vacuum Pump, 14.4 CFM, 1.5 HP

HVAC and automotive service calls require a pump suited to evacuating refrigerant systems. The Orion Motor Tech VPH-C141-A0 combines a two-stage design with a 1.5 HP motor and 14.4 CFM flow. Need fittings for more than one connection size? Its multi-port inlets support several common fitting options. The result is a versatile setup for HVAC, automotive, laboratory, and packaging applications.

Requirements

The pump is designed for systems using R134a, R410A, R22, R142b, and R152a refrigerants. Its inlet options accommodate 1/4-inch SAE, 3/8-inch SAE, and 1/2-inch ACME fittings, helping it work across different service connections. For operation, use pump oil with Viscosity Grade 46. These connection and oil details help technicians prepare the pump for the system being serviced.

Tips for day-to-day use

The gas ballast valve helps remove water vapor during evacuation, supporting a deeper vacuum. The anti-reflux design helps prevent gases from flowing back through the pump, while the oil mist-free cap on the combined fill and exhaust port helps reduce oil mist around the work area. The 22 fl. oz. oil tank is designed for longer operation with fewer refills, and the ergonomic handle makes the pump easier to carry and store between jobs. At or below 70 dB, it also supports a more comfortable workspace than a louder operating environment.

When it makes sense

For service work that calls for a deeper evacuation approach, the two-stage design is a practical alternative to choosing a single-stage pump. Its stated flow rate and ultimate vacuum make it suited to refrigerant-system servicing, while the multiple port sizes add flexibility when working with different connection types. For example, a technician moving between HVAC and automotive service tasks can select the inlet that matches the system’s fitting and use the same pump across those applications.

Buyers praise the pump’s power and quality, while comments about reliability are mixed. That feedback makes the VPH-C141-A0 a compelling match for users prioritizing its documented two-stage design, range of inlet options, and broad service applications. For HVAC and automotive evacuation work that benefits from a high-flow, multi-port pump, it brings key working features together in one portable unit.
