Ventilation systems are not frequently spoken of in most social circles. This is more than likely why you are unfamiliar with the term positive pressure ventilation. Large industrial companies have to use these methods of cleansing and purifying the air so that their employees can safely work in their factories.
Positive pressure ventilation ensures blowing things like debris and particles that would be harmful if humans breathed into their lungs out of the area where the humans are. Positive pressure ventilation also refers to medical procedures and devices that actually breathe for people who have experienced trauma and need to be on a ventilator system. For the purpose of this article we will be speaking of positive pressure ventilation in the capacity to remove unwanted contaminants from the air in a structure so that the remaining air is left breathable by all concerned.
Large fans are used in this ventilation type to push the particles from one area of a structure into another area of the same structure. This is successful because air that is in a high pressure area will automatically attempt to travel to a low pressure area. The fans can cause fire and debris to move from the high pressure area to an established exhaust point where it can be safely removed from the environment.

Many things that are created cause harmful fumes, gases, and particles to enter the air where they are being manufactured. Exhaust systems and fans are used to push the harmful particles from the room and into areas where it can be contained or where it will cause no danger to any living thing.
Schools and residential homes do not require this type of ventilation, it is primarily used in factories, and manufacturing companies that create chemicals, use chemicals, or create something that causes toxic fumes to occur.
There are some places that only need this type of ventilation system in a small portion of their structure. Some of them only need these systems in one room of their buildings. It is possible to buy the correct components to clean the air in these areas without installing the same type of system throughout the structure.
Most of the modern systems that do this have units mounted in the loft space above the rooms. Some of them have units installed in specifically designed cupboards that house them. Series of ducts connect the units and the individual areas within the structure.
You can have decentralized mechanical extract systems incorporated into your building system design so that certain rooms have a continuous extraction rate that can ultimately be increased or decreased from one remote control panel.
This allows contaminated air from wet rooms and areas like these to be removed and replaced with filtered air that has been tempered and rendered perfect. Each building has unique specifications and must have their systems custom designed and installed in order for the air in all areas to be rendered clean and breathable.
