Motor

  • External rotor - capacitor motor.
  • Thermal overload protection as standard feature.
  • Robust motor with ball bearings, maintenance-free.
  • Each speed level can be switched directly using the 230 V supply voltage.
  • Speed cannot be controlled using phase angles or by reducing voltage.

Mounting instructions

  • Can be fitted in any position.
  • ECR-A 25/31 connection diameter 250 mm.
  • When installing with DN 315 ventilation duct, use DN 250/315 extensions provided by the customer.
