Product Description
APPLICATIONS
- Supply and exhaust ventilation systems for various premises suitable for external surface mounting.
- For premises with high requirements to noise level we offer units in low-noise modification (VKMz…Q).
DESIGN
- The fan casing is made of galvanized steel.
- For easy connection and operation the fan can be equipped with the power cord with a plug (VKMz…R).
MOTOR
- The impeller with backward blades is powered by the single-phase motor with external rotor and overheating protection with automatic restart.
- 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 impeller 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.
MOUNTING
- Mounting at any angle to wall or ceiling is performed with fastening brackets supplied with the unit.
- The fan is powered by means of the external terminal box.
- Electric connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
