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.
