Application
The new in-line TT Silent-M fans are enclosed in an especially designed sound insulated casing that ensures silent fan operation in combination with high
aerodynamic characteristics.
The fans are compatible with round air ducts from Ø 100 up to 315 mm.
TT Silent-M fans combine the wide capabilities and high performance
characteristics of both axial and centrifugal fans, thus providing powerful air stream and high pressure. TT Silent-M fans are recommended for air handling systems for many types of commercial and industrial premises with high requirements to noise level, eg. libraries, conference halls, educational institutions, kindergartens, etc.


Design
The external casing is made of polymer-coated steel. The inner casing perforations 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 50mm mineral wool layer.
The especially perforated casing and sound-absorbing material provide sound
attenuation across a broad frequency band. The inner casing and impeller are
made of high-quality durable plastic.
The conic impeller with special blade profiling, increases air flow speed and
provides higher pressure and air capacity 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. The rubber seals on the fan connecting pipes provide airtight connection to the air ducts.
Motor
Single-phase energy efficient two-speed motor with low energy demand. The motor is equipped with thermal switches for motor overheat protection. The ball bearings extend the motor service life up to 40,000hrs at non-stop operation. The motor has IP X4 ingress protection rating.
Speed Control
The two-speed motors are controlled with a built-in switch (V option) or an external switch for multi-speed fans (available separately).
A built-in speed controller (P option), an external TRIAC or autotransformer
speed controller (available separately) enable smooth motor speed control when
connected to the maximum speed terminal. T option models are equipped with an
adjustable turn-off delay timer, adjustable from 2 to 30 minutes.
Mounting
The fan may be mounted in any position and at any angle within a 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 or ceiling.
