Fan Power

Fan power is required to move air both through ventilation equipment and to distribute the air within a room. The measure of this is specific fan power (SFP). In comparison to natural or hybrid ventilation systems, mechanical systems typically have higher SFP requirements. This is because the air in a mechanical unit must be pushed through a filter and, often, a heat exchanger before entering the room, whereas in a natural or hybrid system, the fan power is largely needed for distribution only.  

However, due to the absence of distribution ductwork and the small amount of ductwork typically required to make external connections to the AirMaster unit, the fan pressure required is low. Moreover, the Coanda Effect enables us to distribute tempered air evenly throughout the room without a draught.
