APPLICATIONS

• New inline 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. 
• 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.
