Description
USE

Combined supply and exhaust ventilation systems of various commercial and industrial spaces with stringent noise requirements (such as libraries, conference halls, classrooms, kindergarten playrooms etc.). For ventilation air ducts requiring high pressure, powerful air flow and low noise level. Compatible with Ø 200 up to Ø 400 mm air ducts.

DESIGN

The external casing is made of galvanized steel. Noise and heat insulation is ensured by a acoustic foam layer 30 mm in thickness. The inner casing and the impeller are made of durable high-quality plastic. The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high capacity, powerful pressure and low noise. The fan casing is equipped with an external water-tight terminal box for electrical connections.

  MOTOR

High-efficient direct current EC motor. EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors. EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with restart. EC motor has no friction and wearing parts as capacitor und brushes. Instead a maintenance-free EC controller electronic circuit board is used. The impeller is dynamically balanced.

SPEED CONTROL

The fan speed is controlled with a 0–10 V control signal from the following sources:

  • integrated or external speed controller
  • controller with sensors
  • central BMS system.

The control signal value changes depending on air temperature, pressure, smoke concentration and other parameters. During signal value change the fan with EC motor correspondingly changes the rotations speed and delivers required air volume to the ventilation system.

MOUNTING

The unit is intended for mounting to round air ducts. The fan is installed between the air ducts. The fan casing has mounting brackets to facilitate suspended installation of the fan. While installing the fan, ensure convenient access for subsequent maintenance and repair. Make sure to provide sufficient maintenance access during fan installation. Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box. A single system may have several fans installed in parallel to boost the output capacity or in series to boost the working pressure.
