Remarks
Remarks
In principle, the type test according to 2014/34/EU (ATEX) only takes atmospheric conditions into account (0.8...1.1 bar).
For pressures outside this range use must be assessed and approved by the user.
Adhere to the operating instructions and the type test certificate.
Pack quantity 1 pcs.
