Positive Pressure Ventilation- A Brief Insight Of Its Need

The positive pressure ventilation system works by blowing the dry air into the house. These systems work where there is a lot of space outside the house so they can extract fresh air from outside easily. These are good for the houses that are made of wood in comparison to those that are sealed with aluminum joinery.

Many positive pressure ventilation systems claim that they will recover the heat from the space on the roof. It can be possible in summers but in extremely cold winters there won’t be warm air up as the outer temperature will be very low, so at that time many systems automatically slow down or some even stops working when the temperature falls below certain levels. This is a big concern and the above theory concludes that the ventilation slow down or even stops in winters unless we will use a heater.

The important points to be kept in mind are: to meet the minimum requirements of the ventilation, the system needs a sufficient capacity of fan in order to move the air in the house at a set time interval and various brands offer the units that meet this requirement. If your house is extra large, then you may need a larger unit or more outlets for ventilation. A good filtration is needed and the area where the positive pressure ventilation system will be mounted should be free from dust, fiberglass, bats and other pollutants. The various manufactures want their sales to be topmost so in competition they provide a wide range of features in their product like in filtration some brands provide finer filters as their standard as these filters will restrict the entry of dust in your room. Some filters are washable, some give a guarantee for 1-2 years, and some brands provide regular service of the filters at a time interval of 3-6 months. So, for customers there are choices and choices and more choices.

The basic principle of positive pressure ventilation is that it uses a fan to move air from the outer atmosphere to the inner area of the houses and buildings and thus increasing the pressure on the inner area. As a result smoke, heat and gases are forced out of the house through the vents that are mounted. This process creates a path for moving air that travels from fan to the vent area and thus allowing the positivepressure ventilation to ventilate one area at one time.

The set-up of the positive pressure ventilator is also an easy one and is a two step process. The person will firstly determine where they want the ventilation in their house. Then they generally use doors and windows for this purpose to provide the vent opening, windows can be raised according to the requirements and doors can be blocked. Once the openings have been made than the second step is to set up a fan that will force the air into the structure and it should be positioned according to the structure of the room. These are the basic steps for installation.
