    Condor: German precision in pressure control since 1893

    In the world of compressors and pumps, the Condor brand is a byword for uncompromising quality, safety and technical excellence. As the inventor of the automatic pressure switch, this German family business with more than 130 years of tradition has grown into the world leader in its field.

    History and innovation

    The company was founded in 1893 by August Frede. Although it started out making centrifuges and milking machines, the decisive turning point came in 1935, when Condor was granted the world's first patent for an automatic diaphragm switch for pumps. That moment defined the brand's course as a pioneer in pressure control.

    Why choose Condor components?

    Condor pressure switches (above all the legendary MDR series) are now the standard relied on by respected compressor manufacturers all over the world.

    • Extreme service life: Condor products undergo demanding tests (salt spray or water hammer tests, for example) that confirm their exceptional durability.
    • Safety and certification: Production takes place in Germany to the strictest standards. Condor holds ISO 9001 certification and numerous international approvals, including versions for explosive atmospheres (ATEX).
    • A wide range of uses: From small single-phase compressors (the MDR-1 and MDR-2 series) to powerful industrial machines that require motor overcurrent protection (MDR-3, MDR-5).

    A legend called MDR

    The MDR name has been on the market for more than 80 years. These switches stand out for their rugged design, high switching accuracy and the option of setting the cut-in and cut-out pressure individually. Thanks to integrated unloader valves they also let the electric motor start easily, with no back pressure.

    If you are looking for the best that German engineering has to offer for your compressor or air line, Condor is a safe bet that will repay you with trouble-free operation for many years.
