CENTRIFUGAL AIR MOVERS
Centrifugal air movers are often referred to as blowers. They enhance an incoming airstream by use of a fan wheel. They create a high-pressure airflow by leading the stream of air through a series of tubes and ducts. You receive a steadier flow of air when you choose a centrifugal air mover.
You typically find centrifugal fans in situations that require high pressure drying applications. The one drawback of choosing centrifugal fans is that they are too powerful and high-pressured for use in areas that require more modulated flow.
Think about spaces where computers need cooling or spaces where humans need airflow for comfort. In these situations, a centrifugal fan may be too much.
AXIAL AIR MOVERS
Axial air movers are the most common “fan”. The first electric fans were axial designs based on the look and effect of windmills. They are called axial air movers because of the direction the airflow they create moves. Blades move around an axis, and the air moves out of the fan in the same direction.
Air volume from an axial air mover is high, while the pressure is low. Each axial air mover requires little in the way of power input, so they are highly energy efficient.
Axial air movers are often used in general-purpose use given their high-volume, low-pressure nature. This makes them great for providing comfort in workspaces and for cooling technology in tight spaces, such as servers or computers. Axial air movers are not as adept at drying or air conditioning given their low pressure, so they find less use in large water damage restoration projects.
SERVPRO of Benicia/Martinez/Southeast Vallejo may use one type of air mover on a drying job or a combination depending on the situation.
