Acoustic Aero Core dB Anti Draught Ventilator

Installation Advice

  • Core anti-draught ventilators can be installed in new builds, but benefit the installer most when using in existing walls
  • To fit in existing cavity walls, make a hole through the full cavity wall using either a 5" or 6" core drill, ensuring that there is a small incline towards the outer wall and remove the brickwork debris to fit the vent
  • Large flanges around the external cowl and internal grille allow minor irregularities to be covered easily and also for adequate fixing
  • An external cowl will push onto sleeve and can be silicone sealed to face or screw fixed
