DHA – roof fans with horizontal discharge for private houses

POWERFUL І ENERGY EFFICIENT І ELEGANT

In the course of the optimisation to meet the efficiency standards of the ErP 2015, we succeed to provide the complete range of roof fans with horizontal and vertical discharge with reasonably priced AC motors.

We are simultaneously introducing the complete ranges with highly efficient EC motors, which place themselves well above the ErP 2015 requirements. All product versions are equipped with aerodinamically efficient backward curved impellers. The impellers are mounted directly on the external rotor motor and are commonly dynamically balanced.

The „P“ versions with AC or EC motor, come with an integrated isolator switch.
