The duct fan Vents VKMts 200 is a round centrifugal fan that is built into the duct. Designed for use in supply and exhaust ventilation systems for premises for various purposes. It is possible to install fans on external walls; in this case, it is recommended to use a protective canopy made of galvanized steel. For rooms with increased requirements for noise levels, low-noise options are offered (VKMts...B).

Design
The Vents VKMC 200 fan housing is made of galvanized steel. For more convenient connection and use, the fan can be equipped with a power cord with a plug (VKMts…R).
Motor
Single-phase external rotor motors are equipped with a centrifugal impeller with backward-curved blades. The engine is equipped with built-in thermal protection with automatic restart. 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
The Vents VKMts 200 fan can be installed at any angle relative to the fan axis. 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.
