Helios Fans SSD 400

The Helios SSD 400 is designed to reduce noise on the suction side of ventilation systems, delivering an average sound attenuation of 15 dB. Constructed entirely from galvanized sheet steel, it ensures durability and corrosion resistance in outdoor conditions.

This soundproofing solution is intended for installation on flat roofs and includes insulation panels made from non-combustible building materials classified as class A2. Both sides of the insulation panels are protected by a layer of glass tiles, enhancing safety and longevity.

Mounting is facilitated by a base plate equipped with threaded bushes in accordance with DIN 24155 standards, allowing for secure and standardized attachment. The SSD 400 combines effective noise reduction with robust construction and safe installation features.
