Installation 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.

The DTH is made of cast aluminium, which gives it a high corrosion resistance (Corrosion class C4 according to EN ISO 12944–2).
It is painted in black RAL 7021, a suitable colour for most roofs.
DTH is an extract fan with a horizontal exhaust.
The design ensures an optimum air handling solution with minimum noise.
DTH 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.
DTH roof fan is easy to open for cleaning and maintenance.
DTH fans are designed for use with TGR or TGK roof cowls, for simple and optimal installation.
DTH is simply lowered over the roof cowls, 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 cowls 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.
