  2. Design Add to print

    DTV roof fan


    DTV 150 x 100 DTV is made from cast aluminium, giving it a high corrosion resistance. It is painted in black RAL 7021, a suitable colour for most roofs.

    Vertical exhaust

    DTV vertikal afkast illustration DTV roof fan is an extract fan with vertical exhaust.

    This prevents soiling of the roof and the downdraught of polluted air. It is also less noisy.

    Fan impeller

    DTV hjul 150 x 100 DTV roof fan is ideal for ventilation tasks requiring efficient and economical ventilation.

    The specially developed centrifugal impeller with backward curved blades ensures high efficiency and low operating costs.


    DTV åben 150 x 100 DTV roof fan is easy to open for cleaning and maintenance.

  3. Motor types Add to print

    DTV roof fan

    The motor on the DTV is connected directly to the centrifugal impeller, but lies outside the airflow.

    DTV roof fan is available with two alternative motors:

    • EC motor 
    • single-phase voltage controlled motor

    The motors are made to protection class IP54 and all materials are as a minimum class F (155 °C).  All motor types have integral current overload protection.

    EC motor

    The EC motor is a highly efficient permanent-magnet motor of class IE5 with motor control for a 1 x 230 V connection. The motor control has been specially developed for compatibility with the EXHAUSTO DTV roof fan and, when used with this motor, ensures the lowest possible operating costs.
    The motor control protects the motor from overloading, blocking, over and under voltage, and over heating. It is factory programmed by EXHAUSTO for optimal operation of the fan. It only has to be connected to a 1 X 230 VAC supply and to an EXHAUSTO EFC1P or MAC12 controller.
    The motor controls also provide a Modbus interface for fan control and alarm read-offs etc.

    Single-phase motor:

    Single-phase motors can be selected for the 2 smallest DTV models. All motors are 4-pole with 1400 rpm and permit direct voltage control using EXHAUSTO controllers EFC15, EFC35 and MAC12 (with MPR4/MPR8 module).

  4. Installation Add to print

    DTV roof fan

    DTV fans are designed for use with TGK roof vents, for simple and optimal installation. 

    TGK has 4 threaded connectors for fixing the DTV roof fan. Vibration-damping materials are also supplied to ensure that vibrations from DTV are not transferred to the duct system.

    The TGK roof vent is insulated for sound and condensation and has an integral cable penetration. As an accessory an AOR anti-backdraught shutter and bracket can be selected.
