American Aldes “A” Series centrifugal-type exhaust/supply fans are specifically designed for moderately sized ventilation applications. The fans can be mounted at any angle at any point along the duct work. The straight-through airflow design allows for easy installation. Fans are rated for both indoor and outdoor use. By using American Aldes mounting clamps (optional accessory), the fan can easily be removed from duct work for service.
Fans are constructed in accordance with standard dimensions for spiral duct, eliminating the need for transition pieces. Fan motors are capable of operating in air stream temperatures of 140°F. Motor bearings are the permanently sealed, self-lubricating ball type. All fans are 100-percent speed controllable through a decrease in the voltage by using a solid-state or transformer-type control. “A” Series fans are available as standard or high-performance models in six different sizes.
