  2. Design Add to print



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

    Horizontal exhaust

    DTH afkast 150 x 100

    DTH is an extract fan with a horizontal exhaust.

    The design ensures an optimum air handling solution with minimum noise.

    Fan impeller

  3. Motor types Add to print

    DTH roof fan

    DTH is available with 2 motor types:

    • Single-phase voltage controlled motor
    • EC motor

    The motors are made to protection class IP54 and all materials are as a minimum class F (155 °C). The motor  has 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 DTH models. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO EFC16, EFC35 and MAC12 controllers (with MPR4/MPR8 module).

  4. Installation Add to print

    DTH roof fan

    DTH fans are designed for use with TGR or TGK roof vents, for simple and optimal installation.

    DTH is simply lowered over the roof vent, and its weight holds it in place. Vibration-damping materials are also supplied to ensure that vibrations from DTH are not transferred to the duct system.

    TGR and TGK roof vents are insulated for sound and condensation and have an integral cable penetration. As an accessory an AOR anti-backdraught shutter and bracket can be selected.

  5. Flue gas resistance Add to print

    DTH roof fan

    DTH is able as standard to handle a gas temperature of up to 60°'C.

    When used as a smoke extract fan:

    DTHxxx-4-1 handles up to 200°C for 60 min.

    DTHxxx-4-1EC handles up to 300°C for 60 min.
