The Vectaire PPF9 ositive ressure fan works on the rinci le of introducing tem ered air drawn in through
the loft, creating a ositive ressure in the building, which then dissi ates through o enings around the ro -
erty to rovide a constant background air change. As the moisture content of the air outside is normally lower
than that indoors, the level of humidity is reduced, hel ing to eliminate the damaging effects of condensation.
The tem ered, filtered fresh air is introduced via a short length of flexible ducting attached to a stylish,
ceiling-mounted valve. This discreet valve gently su lies the air in a circular direction, roviding effective,
draught-free ventilation. The system automatically rovides a fresh, tem ered airflow into the home with mini-
mal ower consum tion.
