Very low noise
Minimal depth in enclosure
High through-flow air volume
Uniform air circulation
High reliability
Weather proof and UV resistant
Filter fans are used to provide an optimum climate in enclosures. The interior temperature of an enclosure can be reduced by channelling cooler filtered outside air into the enclosure thus expelling heated internal air. The resulting air flow prevents formation of localised hot pockets and protects the electronic components from overheating. Four integrated axial fans provide a particularly high and uniform air circulation thus contributing to higher reliability. The plastic used for the hood of this filter fan series is highly weather proof and UV light resistant.
