Airlocks are available in your choice of materials and other specifications, as detailed below.

  • Precise internal clearances
  • Rotors of “oversized” stock
  • Larger drive shaft diameters minimize deflection
  • Heavy-duty flanges resist distortion
  • Less operator supervision via automated controls
  • Flange sizes: 4″ to 24″ diameter or square
  • Rugged castings—thick, rigid walls for severe service and extended life
  • Efficiently designed inlet throat provides optimum flow
  • Properly engineered drive packages for reliability
  • Specify:
    • Carbon steel (standard), 304SS, 316SS or Ni-hard
    • Air purge seals
    • Beveled rotors
    • High-temperature design
    • Other alloys and special surface coatings are available


  • Dilute phase conveying and metering material


  • Determined by your material and application

Ideal Material Type:
