Stadium Ventilation BM700/3 - "Black Hole Vario" Anti-Draught Rectangular Ventilator complete with Rustic Red Air Blast Cowl, supplied in three telescopic parts to fit walls 230-375mm.
Benefits of the "Black Hole" range:
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.
Allows air to be pulled through by the appliance when it is operating.
Safety - With draught and light annoyance problems eliminated, the occupier will not be tempted to block off the vent.
"Black Hole" ventilation products provide the answer to the dangerous practice of ventilators being blocked off by occupiers who are being annoyed by draughts. This makes an important contribution to safety. New tests show that while this works the ventilator may not pass the required amount of air when the appliance is operating. THEREFORE IT IS IMPORTANT THAT A SPILLAGE TEST IS CARRIED OUT AS REQUIRED BY THE BRITISH STANDARD.
