Nederman has designed this new line of explosion isolation flap valves to meet the safety conscious combustible dust regulations.

All St1 Explosion Class Dust Types
Nederman’s CARZ-N was designed, tested, and certified under EN16447:2014 to allow usage for all St1 dust types, including metal dust. Nederman is currently in the process of testing CARZ-N to achieve ATEX certification for St2 dust applications.

Push and Pull
The Nederman CARZ-N can be used in both push and pull (positive and negative pressure) applications.

Robust Design
The Nederman CARZ-N explosion isolation flap valve is constructed from welded steel and it is tested and certified for a maximum pressure of 1 bar pressure inside the valve.
