The Stadium BM700/3 double brick rectangular black hole vent with a rustic red cowl is used to provide safety ventilation in areas installed with domestic heating boilers and decorative fuel effect fires. It is supplied with an internal anti-draft baffle to dramatically reduce wind noise from outside by slowing the air flow within the duct by changing its direction, and by the vortices formed, reducing draughts to a minimum.

How the anti-draft Black Hole Ventilator works

Drawn air operation - When a heating appliance is operating, air is drawn through the vent and actually speeds up within the constricted air flow between the vortices. This maintains the correct amount of air in the room or compartment to allow the fuel in the appliance to burn efficiently and flue gases to escape.

Blown air operation - When the appliance is not working, incoming air (blown air or wind) is reduced to a minimum, even when wind levels are high. The energy of the blown air (wind) is quickly dissipated by the restriction of the internal shape and the vortices
