Housing fans

ZIEHL-ABEGG process air fans perform tasks with a high level of responsibility in industrial machines and production systems across a range of different sectors. They ensure functions that would be impossible without defined air transport. Thanks to the optimised fan concept, they perform their tasks with full reliability and functional stability. Only the highest quality is deserving of the title of “Royal League”. ZIEHL-ABEGG housing fans, for example, are used in all areas of ventilation, drying and cooling.
For areas of application containing flammable gases, vapours or dusts, for example, we also offer housing fans in an explosion-proof version with ATEX certification.
