Positive Air Flow System

You can bring in outside air and get positive pressure in the house in one of a few ways but the main way that.

Positive air flow system.

That question is often raised says brennan but decades of building. This directly contrasts with negative air pressure where the flow is drawn into the environment. Positive pressure is a pressure within a system that is greater than the environment that surrounds that system. But won t positive air pressure inside the house create a risk of condensation and moisture damage within the cold walls.

In some laboratories staff members working with potentially hazardous materials may use a negative pressure station. In cleanrooms at hospitals labs and other facilities it can be important to maintain positive or negative pressure depending on the kind of work performed in those environments. Directly above the work space a powerful ventilation and filtration system will draw the air away and through a hepa filter specifically designed to keep workers both in the room and in the building safe from exposure to any hazardous fumes or air borne byproducts.

This is in contrast to a negative pressure room where air is sucked in.

Our positive air pressure systems are designed to reduce the amount of airborne contaminants in a given area by using powerful fans to pull ambient air through hepa or ulpa filters into your work area. In medical settings these rooms prevent the spread of infectious contaminants and maintain sterile or restricted spaces and are also referred to as protective environments positive pressure rooms and airborne infection isolation rooms aiir negative pressure rooms.

By positive pressure i mean that the air pressure inside the house is higher than outside pressure which tends to push air from inside to outside. Use is also made of positive pressure to ensure there is no ingress of the environment. First let s look at how a positive pressure mechanical ventilation system works. Effective positive and negative pressure rooms are an important part of industrial climate control systems.
