Airmovers are devices typically designed for or used in the professional water damage restoration industry. This equipment can be used to direct airflow at or across wet materials, to accelerate evaporation, to provide ventilation, or to create an air pressure differential between tools provided a speed control mechanism allowing a consistent rate of extraction over larger areas.
- Centrifugal Airmovers
- The Centrifugal airmover (e.g. squirrel cage blower, carpet dryer) bas a moving component called an impeller that consists of a central shaft around which a set of blades is positioned. The impeller rotates, causing air to enter the impeller near the shaft and move perpendicularly from the shaft to the outlet due to centrifugal force. A centrifugal airmover producer a higher static pressure for a given air volume than a typical axial designed. Several components of the design influences the performance of a centrifugal airmover (e.g. motor type, impeller design, housing design).
- Axial Airmover
- Axial-flow airmovers have blades that forces air to move inline, parallel to the shaft around which the blades rotate. They move air parallel to the axis of the fan. Generally, axial airmovers produce higher volume airflow and a lower static pressure than centrifugal airmovers.
