TOP 3 SUB FLOOR VENTILATION STRATEGIES
Balanced Air Pressure System
One of our best sellers, the balanced air pressure system is one that is enormously recommended by St George sub floor ventilation. The system is constructed of 2 inline sub floor fans; 1 fan that puffs fresh air in and 1 fan that empties stagnant air out. Base on the size of the underside of the site, our staff of professionals in Mortdale will be able to identify pipeline requirements to ascertain that all foul areas are identified. The design of this system is to equalize the air exchange underside the house with both positive and negative air. It is “balanced” due to the fact that the speed in which the air comes into the sub floor and out of the sub floor at the same rate.
Negative Air Pressure System
This system implies the fitting of exhaust fans to fritter away old air from underneath the site. The collective goal of the negative air pressure system is to check that a major amount of stagnate air is evacuated out as in contrast to equilibrate the air flow beneath the present site.
Positive Air Pressure System
The Positive air pressure system focuses on the fitting of fans to drain air in under the site. Fans are installed with specific pipeline sytems to expel fresh air in to areas below the home.
