Design
The fan housing is made of steel with a polymer coating. Various fan designs are available for wall or in-wall installation.
Motor
The single-phase external rotor motor is equipped with a centrifugal impeller with backward-curved blades. The engine is equipped with built-in thermal protection with automatic restart. For some standard sizes, a motor version with more powerful characteristics is available (VC…S). The use of rolling bearings in the engine ensures a long service life (40,000 hours). To achieve precise performance, low noise levels and safe fan operation, each turbine undergoes dynamic balancing during assembly. The motor in the fan has a protection class of IP 44.
Speed adjustment
Smooth or step adjustment is carried out using a thyristor or autotransformer. Several fans can be connected to one control device simultaneously, provided that the total power and operating current do not exceed the rated parameters of the controller.
It is possible to use a speed controller (supplied separately) RS-1-300
Installation
Fan Vents VTs 125 is intended for wall (models VTs..PN and VTs..VN) or in-wall installation (models VTs..PK and VTs..VK) depending on the version (see below). Connection to the wall is carried out using a mounting plate. 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.
