Low noise fan shape
Suiden rooftop ventilation fans are designed with bell mouthed shape to prevent them from producing “BB” noise due to vibration of the fan air inlet mouth. These roof fans are extra quiet, hence suitable for facilities that require low noise levels.

Ultra-light corrosion resistant FRP dome
The dome made of corrosion resistant FRP material is ideal for protecting the ventilation fan from wind and rain that it is exposed to on the rooftop.

Rain proof roof fans
The fan body utilizes outwards edges, blocking any rainwater brought in by the wind that is not blocked by the dome.

Where?
Suiden low noise rooftop ventilation fans are suitable for ventilation of large facilities, where it is important to maintain a low noise level:
– Warehouse ventilation
– Factory ventilation etc.
