What Sauer Compressors does

Sauer Compressors is the operating brand of J.P. Sauer & Sohn Maschinenbau GmbH, a privately held, family-owned industrial manufacturer founded in Kiel, Germany in 1884. The company designs and builds medium and high-pressure air and gas compressors capable of pressures up to 500 bar, organized into four product lines: SAUER (core high-pressure compressors), HAUG (oil-free and gas-tight piston compressors in the 0.5-110 kW range, derived from the 2017 acquisition of HAUG Kompressoren AG in St. Gallen, Switzerland), GIRODIN (high-pressure naval compressors including the TGM wobble-plate series in production for over 60 years), and EK (compact naval compressors). The product portfolio covers commercial shipping series (Passat, Levante, Mistral, Typhoon), specialized units for technical gases (helium, nitrogen, hydrogen, CO2, oxygen, natural gas), and defense-grade units including the Sauer WP5000, ATEX-certified explosion-proof variants, and breathing air compressors. Principal technologies include a proprietary 3-stage air-cooled compressor design in marine service for over 40 years and the ecc 3.0 compressor control platform.
