DTV
Roof fan
The DTV roof fan is an extraction fan manufactured in cast aluminium, ensuring long-term, problem-free operation. The TGK roof cowl is available for this, ensuring simple and correct ventilation.
The DTV roof fan has a backward-curved B impeller in aluminium with a vertical exhaust, and can be opened for cleaning. DTV is available in 6 sizes: DTV160, -200, -250, -315, -400, and -450.
MOTORS
DTV160 and -200 have a single-phase motor, while the other models have an EC motor.
Get an overview of the individual sizes below.
TEMPERATURE
In normal operation, DTV tolerates temperatures up to 60 °C.
Combustion-gas fan
If there is a need for a certified combustion gas fan, we draw your attention to the SEF roof fan or FSB box fan, described under the product group Fire Safety.
Product advantages
- High corrosion resistance
- Backward curved blades
- High efficiency
- Low operating costs
- Can be mounted on roof cowl TGK

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.

DESIGN
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.
VERTICAL EXHAUST
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 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
