Filter fans are the most cost-effective method - after heat dissipation through the surface of a control cabinet and/or ventilation openings in the enclosure parts of the control cabinets - for dissipating heat from control cabinets.
However, this can only achieve a control cabinet temperature which lies above the ambient temperature.
Standard filter fans optionally in EMC version
When filter fans are used for air conditioning, the cubicle must have openings which allow electromagnetic radiation to pass in and out unobstructed. Filter fans in EMC version offer additional protection when higher requirements are imposed on electromagnetic compatibility.
Filter fan versions
The following filter fans are available on request in 115 V and 230 V versions:
- Standard filter fan IP54, color RAL 7035/7032
- Standard filter fan IP55, color RAL 7035/7032
- Standard filter fan EMC, color RAL 7035/7032, IP54
- Standard filter fan EMC, color RAL 7035/7032, IP55
Note:
For all standard filter fans the useful cooling capacity and air rate are reduced by an average of approx. 30% in combinations of filter fan/ outlet filter / filter mat, and for roof filter fans by approx. 40 %.
