The Bolt Option Ventilation Assembly is a technology based on the concept of the use of the various types of provision for ventilation bricks to install useful items, one of the most important of which are ventilation nets (A) or filters. In the prior state of the art, ventilators were limited to being used for ventilation and installation of nets only, and most ventilation nets were installed utilizing the wall area around the ventilation window perimeters. The invention not only demonstrates that nets (A) can be installed inside or onto ventilator bricks using different techniques, but also expands the range of uses that ventilators can be put to.
