KEY FEATURES:
– Two Stage Design – second stage starts pumping at a lower pressure to pull a deeper ultimate vacuum
– Offset Rotary Vanes – Our proven design creates the deep vacuum conditions needed for a thorough evacuation
– Gas Ballast feature – helps keep the pump oil clean by reducing condensation of moisture
– Iso-Valve – isolates pump from the system with just a 1/4 turn, making it simple to measure rate of rise
– Integral Check Valve – prevents pump oil from being sucked into the system if a power loss occurs
– Die-Cast Aluminum housing – lightweight but durable
– Molded Base – Durable polycarbonate base improves pump balance and minimizes vibration
