VERTICAL OUTLET ROOF FANS

CRDF Series of vertically centered roof type radial fans are made of galvanized sheet metal. Models the body, mounting plate and fan wheels. All models have an external rotor motor, with its closed structure

FAN STRUCTURE
Fan blades are aerodynamically curved and ensure regular flow. Fans
consist of backwards inclined and sparsely arranged fins.

BENEFITS
CRDF roof fans are particularly advantageous in vertical applications, due to the inability to
suck air horizontally. They operate quietly
thanks to their aerodynamic wing structure. The speed can be adjusted by speed controllers. Since rainwater is easily evacuated, water inlet is prevented from entering the chimney.

SPEED CONTROL
Can be provided with optional control device.

AREAS OF USE
Interior It is used in situations where vertical discharge is required under conditions where air cannot be discharged horizontally, in order to improve the air quality of spaces. C roof fans work at
low noise level with an external rotor motor. On the roofs of places where usable air will be refreshed, and on the roofs of buildings opening to a common shaft in chimneys over bathrooms and toilets.
