Covered Air Vent





Ultra-light corrosion resistant FRP dome
The dome made of corrosion resistant FRP material is ideal for protecting the ventilation outlet from wind and rain that it is exposed to on the rooftop. The dome is also very light and durable, and can withstand strong wind.

Fan ready body
These Suiden roof ventilation outlets utilize the same body as Suiden roof fans, and can be equipped with fans at any time when required, without having to change the main body.

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


Suiden rooftop ventilation units are suitable for ventilation of large facilities with large internal spaces, for example:
– Stable ventilation
– Warehouse ventilation
– Factory ventilation etc.
