Design
< p>The Vents VKM 400 fan housing is made of steel with a polymer coating.Motor
Single-phase external rotor motors are equipped with a centrifugal impeller with backward-curved blades. The motors have built-in thermal protection with automatic restart.
The motors are equipped with rolling bearings to ensure a longer service life (40,000 hours). To achieve precise performance, safe operation and low noise levels, each turbine undergoes dynamic balancing during assembly. Motor protection class IP 44.
Speed adjustment
Smooth or step adjustment and carried out using a thyristor or autotransformer. Several fans can be connected to one control device at once, provided that the total power and operating current do not exceed the rated parameters of the controller.
It is possible to use a speed regulator (supplied separately) RS-1-300
Installation
Installation at any angle relative to the fan axis is allowed . Connection to the wall is carried out using mounting brackets, which are included in the delivery set. Power is supplied to the fan through the external terminal box. Electrical connection and installation must be carried out in accordance with the instructions and electrical diagram indicated on the terminal box.
