The KAPTIV-MD-AL is an electronic zero air loss drain with an alarm feature (potential free relay), suitable for applications up to 10 m3/min. (compressor capacity). The alarm contact options are: A1 (Normally Open contact) or A2 (Normally Closed contact).

This exceptionally versatile and compact drain is available as a stock item in multiple voltage options, offering a pressure range from 0 to 16 bar and only weighs 0,5 kg.

With features such as a test button, LED indication and automatic blockage detection, this energy saving electronic drain is the optimum choice for reliable, condensate removal when space is limited (overall height only 74 mm). 

To simplify the installation in restrictive height conditions, the side-inlet adapter is a useful tool.

The KAPTIV-MD-AL’s incredible compact size is a real benefit in applications such as refrigerated dryers and filters. The KAPTIV-MD-AL can be applied in oil lubricated as well as oil-free applications.
