Applications

Supply and exhaust systems for various premises. The steel casing provides reliable operation in case of outdoor installation. For premises with high requirements to the noise level we suggest units in low-noise modification (VKM…Q).

Design

The fan casing is made of steel with polymeric coating. For easy connection and operation the power cord with a plug can be provided (VKM…R).

Motor

The impeller with backward curved blades is powered by the single phase motor with external rotor and overheating protection with automatic restart. Some standard sizes are available is high-powered modifications (VKMS). The VKM…E models are equipped with energy-efficient motor with low energy demand. The motor is equipped with ball bearings for long service life designed for at least 40 000 hours. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating IP 44.

Speed control

Smooth or step speed control with a thyristor or autotransformer speed controller. Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters. The VKM...P models are equipped with a built-in speed controller (available for diameters 100...315).

Mounting

Mounting to wall or ceiling at any angle is performed with fastening brackets supplied with the unit. The fan is powered through the external terminal box.

Electric connection and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.

The fan with electronic temperature and control module (U option)

The ideal solution for ventilation of the premises requiring permanent temperature control, i.e. greenhouses. The fan with the electronic temperature and speed control module provides automatic control of the motor speed (air capacity) depending on air temperature in the air duct or in the room.

The front panel of the electronic module has the following control knobs:

speed control knob for setting the motor speed;
thermostat control knob for setting the temperature set point;
thermostat indicator light.

VKM...Un - the model with an external temperature sensor fixed on a 4 m cable (Un / U1n option). The temoerature sensor has mechanial protection.
