ROOFTOP VENTILATION FANS | Explosion proof series
SRF-R50FD1
SRF-R60FD1
SRF-R75FD1
SRF-R90FD1
Roof Fan Features:
Explosive proof construction
These Suiden hazardous location roof fans are specially made to be able to safely ventilate facilities with explosive or combustible gas.
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.
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.
Rain proof
The fan body utilizes outwards edges, blocking rainwater brought in by the wind that is not blocked by the dome.
Roof Fan Applications:
Where?
Suiden explosion proof rooftop ventilation fans are suitable for ventilating hazardous locations with explosive or combustible gas:
- Factory ventilation
- Refinary ventilation
etc.
