with an external temperature sensor fixed on the cable, 4 m long (Un / U1n option).ĬONTROL LOGIC OF THE FAN WITH THE ELECTRONIC TEMPERATURE AND SPEED CONTROL MODULE. with a temperature sensor integrated inside the fan air duct (U/U1 option). The fan is available in two modifications: thermostat control knob for setting the temperature set point. speed control knob for setting the motor speed. The front panel of the electronic module has the following control knobs: The fan with the electronic temperature and speed control module provides automatic control of motor speed (air capacity) depending on the air temperature in the air duct or in the room. The ideal solution for ventilation of the premises with high demands to permanent temperature control e.g. THE FAN WITH ELECTRONIC MODULE OF THE TEMPERATURE SENSOR AND SPEED CONTROLLER («U» OPTION) The fan casing is equipped with fixing brackets for fastening to the floor, wall or ceiling. #SILENT SIFTER MINIMUM DELAY SERIES#
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 may be mounted at any place and at any angle within the ductwork system.TT Silent-M fan with a built-in speed controller T option models are equipped with an adjustable turn-off delay timer, adjustable from 2 to 30 minutes.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.TT Silent-M fan with a three-position speed switch The double-speed motors are controlled with a built-in switch («V»option) or an external switch for multi-speed fans (available upon separate order).The motor has IP X4 ingress protection rating.The ball bearings extend the motor service life up to 40 000 hrs.The motor is equipped with thermal switches for the motor overheating protection. Single-phase energy efficient double-speed motor with low energy demand. The fan casing is equipped with an airtight terminal box for connection to power mains.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.
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 inner casing and the impeller are made of high-quality durable plastic. The specially perforated casing and sound-absorbing material provide sound attenuation in a broad frequency band. The casing is internally heat- and the sound-insulated with 50 mm mineral wool layer. The inner casing perforation let sound waves pass through the holes and fall at a specific angle to the sound-absorbing layer. The external casing is made of polymer-coated steel. in libraries, conference halls, educational institutions, kindergartens, etc. 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. 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 fans are compatible with round air ducts from Ø 100 up to 450 mm. 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.
