EKH/DKH – Backward-curved radial centrifugal made of sheet steel.

Easy installation via mm standard flange.

Fans can be installed in any position.

Simple electrical connection via terminal box fitted to the outside.

Terminal box in protection class IP 54 (explosion-proof executions with wires led to the outside).

100% speed controllable by auto transformer or electronic controller.

Motor protection by thermal contacts as standard (Explosion-proof motors with PTC thermistors).

Extremely low starting currents. compact design.

Casing made of galvanized sheet steel formed as a rectangular air duct, and plastic corners made from reinforced polyamide, with standard tube flanges at inlet and outlet sides.

The impellers are fitted directly onto the rotor of the external rotor motor.
The motorized impellers are balanced at two levels according to G 2.5 (DIN ISO 1940).
The performance curves for these fans have been established using the inlet test method in the test chamber according to DIN 24 163, mounting position D (connected at both sides). The curves indicate the static pressure increase Δ P as a function of the volume flow. The dynamic pressure Δ pd2 shown in the performance curves refers to the flange cross-section of the fan housing.
