DYNAIR PR-AC ATEX Centrifugal fans in plastic material

The PR-AC ATX is the special ATEX version of the PR-AC series, suitable for extraction smoke, or humid and corrosive (but not abrasive) vapours between -20°C and +40°C. The materials and specific components used make these fans suitable for use in plants listed in the ATEX directive 2014/34/EU. These devices are particularly ideal in zone 2 (3G) and zone 22 (3D). The backward curved blade impeller provides low noise operation while maintaining high efficiency. When its lifetime is finished, the PR-AC ATX fan can be easily recycled thanks to the materials it is made of.
