Roof fans

The high-performance RDA fan impresses with its outstanding design, innovative finishes, and corrosion-resistant aluminum case. But even more surprising is its price. After all, quality doesn't have to break the bank: save money during the initial purchase, operation, installation, and maintenance thanks to:

• a premium basic version at an unbeatable price
• low heat loss
• long, maintenance-free operation
• easy assembly without special tools
• easy to swivel out from inside the case

Product design

For us, extraordinary is the norm.

Nicotra Gebhardt is known for its extremely innovative research and development. A great example is the genovent®, which allows for a variety of extraordinary solutions at no extra charge:

• The genovent® is a simple plug-and-play solution for all installations, even when replacing an existing fan.
• Its smart design makes it particularly easy and inexpensive to open up the fan for maintenance and inspection: simply unscrew the screws!
• The exhaust shutters protect the fan from rain and snow, prevent unnecessary heat loss from the ducts, and eliminate the need to install a separate shutter under the fan.
• The genovent® provides for powerful vertical discharge to keep rooftops free of dirt and prevent short circuits in the ventilation system.
• The integrated sound insulation feature on the RDA 32 reduces noise on the outlet side by an average of 7 dB(A).
• Energy is saved thanks to the ability to install and adjust the fan on a precise location. We also offer solutions that make use of adjustable-voltage and pole-changing motors, external frequency converters, and energy-saving brushless DC technology.
