Installation DTV fans are designed for use with TGK roof cowls, 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 cowl is insulated for sound and condensation and has a built-in cable penetration. An AOR anti-backdraught shutter and bracket can be selected as accessories.

DTV 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.
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.
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 roof fan is easy to open for cleaning and maintenance.
DTV fans are designed for use with TGK roof cowls, 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 cowl is insulated for sound and condensation and has a built-in cable penetration. An AOR anti-backdraught shutter and bracket can be selected as accessories.
