The CDF140 condensate drain is designed for discharging medium to large amounts of liquids up to 16 bar of non-aggressive condensate out of compressed air systems. The condensate drain is mounted outside the pressurised housing from which the liquid is to be discharged (external drain). The CDF140 must be directly connected (free passage) to the pressurised housing.

The CDF140 condensate drain is designed for fully automatic and level-controlled discharging of liquids to the environment. The CFD140 has its own pressure-proof housing and therefore an integrated liquid collect-ing vessel. 

The pressure-proof floater rising with the liquid column op-erates a directly controlled valve and activates opening of the valve and thus discharging of the liquid. In the same way the valve is closed with a falling liquid level before any compressed air may escape. In depressur-ised state the valve is closed (NC design).

The drain is provided with a separate manual drain which serves to depressurise the connected pressure housing and the drain itself (manual venting and draining).

The CDF140 is mounted using the G 1/2 connection thread at the inlet. The outlet also has a G 1/2 connection thread for the mounting of fittings (e.g. hose nozzles or quick connectors). We recommend using a ball valve with screwed joints (optional CAKR mounting kit) between the CDF140 and the pressure housing from which the liquid is to be discharged. In this way the CDF140 can be removed and cleaned without the need for depressurising the connected pressure housing.
