Features


  • Stops wind blasting in - The air flow within the duct is slowed down by the change of direction and by the vortices formed, reducing draughts to a minimum.
  • Stops light showing through - The occupier cannot see through the ventilator and is less likely to be worried that insects and vermin may enter the house through it.
  • Stops light shining out - Night flying insects like moths, craneflies, and mosquitoes are not attracted in.
  • Absorbs outside noise - Reduces the penetration of traffic noise. The internal construction works as a sound baffle.
  • Safety - With draught and light annoyance problems eliminated, the occupier will not be tempted to block off the vent.
