SEF(R) fans have housings made of galvanised steel with two screw-mounting feet. The housing is designed in such a way as to ensure the high rigidity of the system. The rotor crown is made of stainless steel and the blades are made of a high-strength aluminium alloy. All materials, parts and associated components conform to the relevant standards and directives. There are also certified accessories in the SMAY range, such as mounting feet, anti-vibration mounts, elastic connection pipes, intake nozzles, protection mesh, diffusers and attenuators.


SMAY fans can be mounted both vertically and horizontally while maintaining the certification of the units. This ensures greater flexibility when designing optimum solutions.

On the other hand, a junction box on the fan housing makes it possible to make electrical connections quickly and provides convenient access during servicing operations.

The fan has been designed and adjusted for continuous operation and is highly resistant to mechanical impact, corrosion, temperature and humidity. The motors are made in accordance with ingress protection rating IP55, holding insulation class H and utilise the IC418 cooling method.
