|
-
For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
-
Motor protection rating IP 44.
|
SPEED CONTROL |
|
- Several fans can be connected to one controller in case the total power and operating current do not exceed the rated controller values.
|
MOUNTING |
-
The fan is mounted on the roof directly above the ventilating duct or shaft and is firmly fixed to the flat surface by means of a connecting plate.
-
Electrical connection and installation shall beperformed in compliance with the manual and circuit diagram on the terminal box.
|
-
For connection of the fans to round air ducts use the following accessories: KKV damper, GVK flexible connector, FKV counter flange.
-
