Fly Screen Air Bricks
The Fly Screen air bricks are supplied with a fitted copper mesh which is especially useful to prevent ingress of foreign objects into ducting and ventilation systems, ie. insects, cigarettes, matches, gum and litter etc.
They have been installed in a number of medical establishments and dentists especially in listed buildings and are very effective at preventing the ingress of summer flies and midges. At low levels they are especially useful in preventing rodents gaining access into properties. The removable mesh can be cleaned and replaced as part of a planned maintenance system cutting down accumulation of dirt within ventilation ducting when fitted on air inlets and so reducing the risk of fires.
