    Application

    New series of the duct fans VENTS TT-MD enclosed in a special sound-insulated casing that ensures low-noise operation of the fans at high aerodynamic characteristics. The fans are compatible with Ø 355, 400, 450, 500 air ducts. VENTS TT-MD 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 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

    Energy efficient motor with low energy demand. The motor is equipped with thermal switches for the m-tor 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.

    Speed control

    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. Maximum fan speed does not depend on the current frequency. The fan is compatible both with 50 or 60 Hz power mains. The fans may be integrated into a unified data processing control system. The specially designed software provides precise control of all the fans integrated into the system. The computer displays all the system parameters. Each fan in the system may be individually adjusted.

    Mounting

    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.
