Low noise Roof Filter Fan RFF 018 Series
■ 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.
