New inline VENTS TT Silent-M fans are enclosed in a specially 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 450 mm.
The VENTS TT Silent-M fans combine wide capabilities and high performance characteristics of both axial and centrifugal fans, thus providing powerful air stream and high pressure.
The VENTS TT Silent-M fans are recommended as a component of the 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 external 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 the sound-insulated with 50 mm mineral wool layer.
The specially perforated casing and sound-absorbing material provide sound attenuation in a broad frequency band.
The inner casing and the impeller are made of high-quality durable plastic.
Due to the conic impeller and special blade profiling the circumferential air speed increases thus providing higher air pressure and 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.
Single-phase energy efficient double-speed motor with low energy demand.
The motor is equipped with thermal switches for the motor overheating protection.
The ball bearings extend the motor service life up to 40 000 hrs. at non-stop operation.
The motor has IP X4 ingress protection rating.
The basic double-speed motors need to be equiped with an external switch for multi-speed fans (available upon separate order).
The double-speed motors controlled with a built-in switch («V»option)
TT Silent-M fan with a three-position speed switch
A built-in speed controller (P option), an external TRIAC or autotransformer speed controller (available upon separate order) 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.
TT Silent-M fan with a built-in speed controller
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 or ceiling.
