    Automatical condensate discharge without compressed air losses

    The MD Mechanical Drain discharges the condensate automatically and without compressed air losses, up to 16 bar. A floating body rises and falls with the condensate level in a collecting chamber; and opens/closes a mechanical drain valve. The condensate collecting chamber is closed off from the compressed air flow when the drain is depressurized.

    The drain is equipped with an integrated venting function, which prevents the risks of possible air slots. The MD has a well-proven, rugged metal design with threaded connections at inlet and outlet.
