The new generation of roof-mounted fans (EC version) is one system for all sizes: only one mounting cut-out is needed for all output categories. Air routing with minimal pressure losses ensures a high level of efficiency, while an innovative clamping attachment supports a high protection category of IP54. The fan may be activated via the control interface with tacho signal output integrated as standard, and monitoring of the fan speed and function is supported.

A chopped fiber filter can be used to increase the protection category to IP 55 (see accessories).
For even more efficient operation or for monitoring the fans, we recommend the use of an EC speed control.
Easy locking with innovative clamping attachment
|
Simple to fit and maintain ◾ Innovative clamping attachment supports flexible locking, optionally from the outside or inside ◾ Easy electrical connection via plug terminal ◾ Good accessibility permits fast filter mat changes |
High protection category ◾ IP 55 as standard, thanks to a sophisticated labyrinth system and high-quality foamed-in seal ◾ International approvals and permits |

The SK 3243300 outlet filter is used in conjunction with the associated filter fan to dissipate lost heat out of the enclosures, to ventilate the enclosure and to protect temperature-sensitive components. This is done via the direct supply of ambient air that must be below the permissible temperature inside the enclosure.

3 Q:What IP / NEMA ingress rating can be achieved?
A: Out of the box (without filter mat): IP 21
With the included pleated filter installed: IP 54 / NEMA 12 (achieved via an innovative toolless clamping attachment that seals tightly against the horizontal roof plate).
A: A miniature circuit-breaker or pre-fuse rated at 3 A is required for individual line protection. The internal radial EC motors feature thermal winding protection to autonomously safeguard against prolonged electrical overload.
