Key Features

  • Twin Cylinder
  • 15 microns ultimate vacuum
  • Forced Oil Circulation
  • Internal Check Valve
  • Integrated Cylinder Structure
  • Lifting Hook

Overview

The NAVAC 4 CFM vacuum pump uses forced oil lubrication to ensure vane sealing, cooling, and high reliability. The vacuum pump features a simple oil fill port and a large oil window to provide valuable information like oil level and oil quality. The oil drain valve at the bottom ensures faster, more thorough emptying.

The NAVAC NP4DP two-stage rotary vane pump uses a gas ballast system to pump large volumes of vapor without condensation inside the pump. This prevents the accumulation of fluids that would adversely affect the pump’s service life.


The 4CFM vacuum pump includes an oil-mist filter to effectively prevent impurities from entering the pump cavity and an internal check valve that prevents oil backflow into the system during a power failure.

The NAVAC vacuum pump can be used with refrigerants such as R-12, R-22, R410A, R404A, and R134A and has a lifting hook for safe and convenient hoisting to rooftops.
