Very low noise
Minimal depth in enclosure
High through-flow air volume
Uniform air circulation
High reliability
Time-saving installation
Roof filter fans and roof exit filters find use in enclosures, from which warm air has to be diverted due to increased heat development. The ready-to-connect and low-noise roof filter fan, which houses four axial fans, is used to expel warm air from within the enclosure which has been generated by the stray power of the components. The roof exit filter provides passive ventilation.

Approvals |
Important note: For reasons of pressure compensation the roof filter fan must always be operated in combination with another filter fan (e.g. Art. No. 01803.0-00) or a passive intake filter (e.g. Art. No. 11803.0-00)
