High-pressure naval compressors

High-pressure navy compressors

As long ago as 1955, Sauer delivered the first high-pressure compressor to the nascent West German Navy. Since then, many thousand compressors have been delivered to navies all over the world. Specially designed for use on corvettes, frigates, destroyers, mine sweepers, mine hunters, aircraft carriers and submarines, these compressors have worked to the full satisfaction of their naval users. Thanks to our broadly based present-day portfolio we can most certainly supply you with precisely the right high-pressure compressor to meet your specific needs.

Air-cooled high-pressure piston compressors

Main features:

  • Direct-drive design means less maintenance, higher reliability, greater efficiency and less noise than a V-belt drive
  • Simple maintenance as piston and cylinder are each made in one piece
  • Low blow-by thanks to use of multiple classic piston rings
  • Best clearance between piston and liner for higher reliability and high temperatures
