Mastercool 90067-220-SV Professional 2-Stage Vacuum Pump with Solenoid Valve - 7.5 CFM

Professional-grade 2-stage vacuum pump with integrated solenoid valve for automated high-capacity operation. Elite ball bearing design delivers exceptional performance with 178 litres per minute (7.5 CFM at 50 Hz) free air displacement and deep vacuum capability down to 25 microns. The built-in solenoid valve automatically isolates the pump from the system when target vacuum is reached, preventing oil backflow and enabling unattended operation. Ideal for medium to large commercial systems, high-volume workshops, and professional service operations. 220V/50Hz European specification.

• Workshop and garage use

Benefits:

Integrated solenoid valve transforms this high-capacity professional 2-stage pump into an automated evacuation powerhouse. When target vacuum is reached, the solenoid valve automatically isolates the pump from the system, preventing oil backflow and protecting both the pump and the A/C system. This enables unattended operation - set the pump running on a large system and move on to other tasks whilst evacuation completes automatically. Maximises productivity in high-volume workshops. Elite ball bearing design ensures smooth, reliable operation and extended service life. 178 litres/min capacity (7.5 CFM at 50 Hz) handles medium to large systems efficiently, reducing service time dramatically. 2-stage design delivers deep vacuum capability down to 25 microns, ensuring complete moisture and non-condensable removal. The 1/2 HP motor provides reliable cold condition start-up and sustained performance. Gas ballast valve enables effective moisture removal without contaminating pump oil. Oil sight glass enables quick visual oil level checks without stopping work. Thermal overload protection prevents motor damage during extended use. Professional-grade construction withstands demanding daily use in busy workshops. Complete service parts available including replacement cartridge (90167-R) and seal service kit (90062-11-SEAL). Perfect for professional technicians and high-volume service shops who need maximum capacity with automated operation. The combination of high capacity, elite ball bearing design, and solenoid valve automation delivers unmatched productivity for demanding professional applications.
