The durable external casing is made of polymer coated steel. The inner casing perforation let’s sound waves pass through the holes and fall at a specific angle to the sound absorbing layer. The casing is internally heat and sound insulated with a 50mm mineral layer and the conic impeller with special blade profiling increases air flow speed and provides higher pressure. The diffuser, specially profiled impeller and directing vanes at the outlet from the fan casing distribute airflow in such a way as to attain the best combination of performance and pressure at low noise levels. The fans can be mounted at any place or angle within the ductwork.

Several fans can be installed in parallel in the same system to achieve a higher air capacity or in series to achieve higher pressure.
