DESCRIPTION:
The DTH roof fan is an extraction ventilator manufactured in cast aluminium, ensuring long-term, problem-free operation. TGK/TGR roof cowls are available for this, ensuring simple and correct ventilation.

The DTH roof fan has a backward-curved B impeller in aluminium with a horizontal air exhaust and can be opened for cleaning. DTH is available in 5 sizes: DTH160, -200, -250, -315 and -400.

MOTORS:
DTH160 and -200 have a single-phase motor, while the other models have an EC motor.

TEMPERATURE:
In normal operation, DTH tolerates temperatures up to 60 °C.

Combustion-gas fan
If a certified fire gas fan is required, we refer to SEF roof fan.

  • P1 is the maximum absorbed power from the mains supply, where P2 is the motor's nominal output.
  • Stated data for for t = 20°C
  • Density = 1.2 /m3
  • Values are based on the use of a transition piece equivalent to OGSR
  • Gas temperature: min. -12°C, max. +60° C
  • Ambient temperature: Max. +40° C
  • Pressure ratio: < 1,11
  • other points in acc. with EC327/2011 - see product instructions

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.

DESIGN

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.

HORIZONTAL EXHAUST

DTH is an extract fan with a horizontal exhaust.

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

FAN IMPELLER

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.

SERVICE

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.
