Thepositive pressure ventilation system works by blowing thedry air into the house. These systems work where there is a lot of spaceoutside the house so they can extract fresh air from outside easily. These aregood for the houses that are made of wood in comparison to those that aresealed with aluminum joinery. Many positive pressure ventilation systemsclaim that they will recover the heat from the space on the roof. It can bepossible in summers but in extremely cold winters there wont be warm air up asthe outer temperature will be very low, so at that time many systemsautomatically slow down or some even stops working when the temperature fallsbelow certain levels. This is a big concern and the above theory concludes thatthe ventilation slow down or even stops in winters unless we will use a heater.The important points tobe kept in mind are: to meet the minimum requirements of the ventilation, thesystem needs a sufficient capacity of fan in order to move the air in the houseat a set time interval and various brands offer the units that meet thisrequirement. If your house is extra large, then you may need a larger unit ormore outlets for ventilation. A good filtration is needed and the area wherethe positive pressure ventilationsystem will be mounted should be free from dust, fiberglass, bats and otherpollutants. The various manufactures want their sales to be topmost so incompetition they provide a wide range of features in their product like infiltration some brands provide finer filters as their standard as these filterswill restrict the entry of dust in your room. Some filters are washable, somegive a guarantee for 1-2 years, and some brands provide regular service of thefilters at a time interval of 3-6 months. So, for customers there are choicesand choices and more choices.The basic principle of positive pressure ventilation is thatit uses a fan to move air from the outer atmosphere to the inner area of thehouses and buildings and thus increasing the pressure on the inner area. As aresult smoke, heat and gases are forced out of the house through the vents thatare mounted. This process creates a path for moving air that travels from fanto the vent area and thus allowing the positivepressure ventilation to ventilateone area at one time.The set-up of the positive pressure ventilator is also aneasy one and is a two step process. The person will firstly determine wherethey want the ventilation in their house. Then they generally use doors andwindows for this purpose to provide the vent opening, windows can be raisedaccording to the requirements and doors can be blocked. Once the openings havebeen made than the second step is to set up a fan that will force the air intothe structure and it should be positioned according to the structure of theroom. These are the basic steps for installation.
