Studies have demonstrated that the filter may be suitably protected using devices compliant with ATEX 94/9/EC and EN 1127-1. The user will be responsible in accordance with 99/92/EC (ATEX 137) if such protective devices are not ordered and/or installed.
The AIRALT Ex is a very high efficiency dry powder filtering machine. It is specifically designed to work in environments where high explosion protection is required in accordance with ATEX 94/9/EC.
Its necessary high structural resistance is the result of FEM (Finite Element Method) analysis design and complies with UNI EN 288-4 specifications for welding processes and consistency of the project complying with 97/23 (PED) rule. The elevated design and production standards implemented by Coral S.p.A. have been maximised to develop a standard model (with Pred=1barg) and a special version (with Pred=2 barg). AIRALT Ex filters can be used in the presence of class ST3 powder thanks to their excellent mechanical resistance to excessive pressure. Used in combination with explosion detection and suppression systems, AIRALT Ex is the best that the filtering market can offer today in terms of technology and safety.
