VENTS TT Silent-MD 450-3 EC

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.

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. 

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. 

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.
