CRDF

VERTICAL OUTLET ROOF FANS
Fan components and material properties CRDF Series of vertical centered roof type centrifugal fans are made of galvanized sheet metal. housing, mounting plate and fan wheels models. All models are equipped with an external rotor motor with a closed structure. The device can cool the air to max.40ºC.

FAN STRUCTURE
Fan blades are aerodynamically curved and provide regular flow. Fans consist of backward curved and sparsely arranged fins.

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

MATERIAL
Optional control devices can be provided. Speed control can be done with linear voltage regulator in 1~phase products (see Speed control with frequency converter in 3-phase products (see VHAN accessory)

SPEED CONTROL
Can be provided with optional controller.

AREAS OF USE
Used in cases where vertical discharge is required under conditions where air cannot be discharged horizontally to improve indoor air quality. C roof fans operate at: low noise level with an external rotor motor. Used on roofs of places where air is to be refreshed, in chimneys over bathrooms and toilets, roofs of buildings opening to a common shaft.
