4 CFM Vacuum Pump

Robinair vacuum pump features below. See Specifications tab for voltage, micron rating, recommended uses, dimensions and more.

  • Iso-Valve™: Isolates the pump from the system with just a quarter-turn
  • Gas ballast: Allows moist air to pass through the pump to mix with dry air, reducing condensation
  • Heavy-duty motor: Sealed bearing, high-torque design for easy startup and efficient operation
  • 2-stage rotary vane design: Powerful, quiet high vacuum capability for maximum moisture removal and reduced evacuation time
  • Offset rotary vanes: Unique design builds more compression, reducing system pressure and removing more moisture
  • Molded polycarbonate base: Reduces vibration and provides balance during operation
  • Angled oil drain valve: faster, more complete draining
  • Top oil fill port: Better access when refilling oil
  • Cast aluminum body: Lightweight and durable die-cast aluminum reduces weight and creates a strong, durable pump
  • Quality: Performance-tested to meet Robinair’s quality, durability and longevity standards
  •  Intake screen: Prevents foreign matter from entering pumping chamber. External exhaust filter separates oil vapor from exhaust flow
  • Brass intakes: Reliable brass intake valves with Flare, ACME or both style fittings with tethered caps
