Mastercool 90066-B 6 CFM Single-Stage Vacuum Pump

Description

The Mastercool 90066-B 6 CFM Single-Stage Vacuum Pump provides dependable evacuation performance for technicians who need consistent results during A/C service work. Because it offers 6 CFM free air displacement, the pump removes air and moisture efficiently during system evacuation.

This single-stage pump achieves an ultimate vacuum of 80 microns, which helps prepare systems properly before refrigerant charging. As a result, technicians can improve system reliability while reducing the risk of moisture-related issues. In addition, the thermally protected motor and high-volume cooling fan help maintain stable operation during extended service jobs.

The 90066-B includes a large oil sight glass with max/min indicators, so oil level checks remain quick and easy. Therefore, routine maintenance becomes simpler and more consistent. Although the manufacturer has discontinued this model, remaining inventory continues to provide reliable performance for professional shop and mobile use.
