Description
APPLICATIONS
  • New inline VENTS TT Silent-MD EC fans are enclosed in a specially designed sound-insulated casing that ensures low-noise operation combined with high aerodynamic characteristics.

  • The fans are compatible with Ø 355, 400, 450 air ducts. 

  • VENTS TT Silent-MD EC combine wide capabilities and high performance features of both axial and centrifugal fans, thus providing powerful air stream and high pressure. 

  • The fans are used as a component part of air handling systems for various commercial and industrial premises with high requirements to noise level, i.e. in libraries, conference halls, educational institutions, kindergartens, etc.

DESIGN
  • The fan casing is made of polymer-coated steel.

  • The inner casing perforation let sound waves pass through the holes and fall at a specific angle to the sound-absorbing layer.

  • The casing is internally heat- and sound-insulated with mineral wool.

  • The specially perforated casing and sound-absorbing material provide sound attenuation in a broad frequency band.

  • The conic impeller with special blade profiling increase air flow speed and provide higher pressure and air capacity as compared to standard axial fans. 

  • The diffuser, the specially profiled impeller and the directing vanes at outlet from the fan casing distribute air flow in such a way as to attain the best combination of high performance and high pressure at low noise level.
  • The fan casing is equipped with an airtight terminal box for connection to power mains.

     

MOTOR
  • High-efficient electronically commutated direct current motor. Such motors are the most stateof-the-art energy saving solution.

  • EC motors are featured with high performance and total speed controllable range. 

  • High efficiency reaching 90% is the premium advantage of the electronically-commutated motors.
  • The motors are equipped with ball bearings designed for at least 40 000 operating hours.
  • For precise features, safe operation and low noise, each impeller is dynamically balanced during assembly.
  • Motor ingress protection rating IP 44.
SPEED CONTROL
  • The fan is controlled with an external 0-10 V control signal. The fan capacity is regulated depending on temperature and pressure level, smoke content, etc.

  • The rotation speed of the EC motor changes proportionally to fluctuations of the control parameter and the fan delivers a required air volume to the ventilation system.

  • Maximum fan speed does not depend on the current frequency. The fan is compatible both with 50 or 60 Hz power mains.
  • The fans may be integrated into a unified data processing control system.
  • The specially designed software provides precise control of all the fans integrated into the system.
  • The computer displays all the system parameters. Each fan in the system may be individually adjusted.
MOUNTING
  • The fan may be mounted at any place and at any angle within the ductwork system.
  • Several fans may be installed in one system in parallel to attain higher air capacity or in series to increase operating pressure in the system.
  • The fan casing is equipped with fixing brackets for fastening to the floor, wall.
