The standard model drying pump for Kriegsmarine optics, made by Carl Zeiss Jena
Trockengerät C/1931, number 1052

A further developed device from the Nedinsco shown in another post.
this one can run on 110V and 220V, and on both AC and DC. The engine is made by AEG

This unit appears nearly unused.

The champers below hold Chlorcalium. In the bottom right there is a window to check the condition of the material.
the original transport case holds the instructions for use and the tool to open the champers

In use for a DF. 10x80 20° schr. Einblick
The valves of the optic made it possible to create a pressure inside the optic with the pump, as for this model of 0.1 atü
This held moist out of the optic, for a bit

Martin, have you actually powered it up and it worked?

Martin Soerensen
