The CAS14 and CAS14S are austenitic stainless steel ball float

gas/air drain traps.

They provide efficient condensate drainage from compressed air

and other gas systems, allowing the process to operate to its optimum

potential.

The connections are in the vertical plane for flow downwards.

Body and cover castings are produced by a T

ÜV approved supplier

in accordance with AD-Merkblatt WO/TRD100.
