• Robinair's CoolTech 4 CFM Two Stage Vacuum Pump has a 1/3 HP motor.
• Two stage design. 1/2IN ACME and 1/4IN MFL intake fitting. Iso-Valve isolates pump from system, making it easy to measure rate of rise.
• Vacuum pump efficiency depends largely on the purity of the vacuum pump oil.
• The gas ballast feature helps keep the oil clean for a longer time by introducing a small amount of dry atmospheric air to prevent condensation of moisture within the pumping chamber.
• Two stage design for greater efficiency the second stage of the two-stage design starts pumping at a lower pressure to pull a deeper ultimate vacuum.
• The inlet filter prevents contaminants from entering the pumping chamber; check valve prevents oil from backing up into system during a power outage.
• Heavy duty motor is easy to start and efficient to operate. The power switch is located on the handle assembly to protect it from accidentally being turned on or off.
• Gas ballast keeps oil clean and dry
• Inlet feature prevents pump contamination
• Evacuates today’s tighter systems with their increased sensitivity to contaminants
• Offset rotary vanes work in conjunction with the vacuum pump oil to create a powerful compression inside the pumping chamber
• Sure grip handle stays cool to the touch and directs exhaust away from you
• 20 microns ultimate vacuum
