Benefits:

Professional 2-stage design delivers superior vacuum depth and faster evacuation times compared to single-stage pumps. 178 litres/min capacity handles medium to large systems efficiently, reducing service time and improving productivity. The ultimate vacuum of 25 microns ensures the complete removal of moisture and non-condensable gases, which are critical for system longevity and optimal performance. The 1/2 HP motor provides reliable cold-weather start-up, essential for professional use. Three inlet ports (1/4" FL, 3/8" FL, 1/2" ACME) offer maximum flexibility - the 1/2" ACME port is specifically designed for automotive R134a systems. The manifold valve allows isolation from the system for convenient operation. The gas ballast valve enables effective moisture removal without contaminating the pump oil. The oil sight glass allows for quick visual oil level checks without stopping work. Robust construction withstands demanding professional use. Durable and time-tested Mastercool quality stands up to the most gruelling conditions and provides years of reliable service.
