Extraction arm for workplaces with requirements for safe handling of explosive gases and dust. The PR EXC/EXD has the same unique features and design as the PR. The differences lie in the grounded structure and the fact that PR EXC/EXD meets the requirements of the ATEX Directive 2014/34/EU Category 2 for gases and dust. The product is available in two versions: PR EXC with black chemical-resistant PE hose and PR EXD with semi-transparent white PU hose for dust-related pollutants.
