Positive Pressure

The loft mounted positive pressure fan draws air in from outside, which then passes through a filter before entering the building by means of a ceiling diffuser. All stale air is then forced out through the natural forms of ventilation, such as trickle vents as well as through any leaks in the building. In fact the system acts like an air plug, plugging the leaks by forcing stale air out through them. Also available with built-in heater, an ideal solution for older properties and renovations. Features Lo-Carbon energy efficient motor extremely low running costs.
