These fans are known for their economical use of energy and excellent ease of control. They can be varied in speed to match the airflow demand, and operate at high efficiency levels. An excellent choice for exhaust or supply applications where quieter performance and easy installation are important. Perfect for commercial and institutional structures such as offices, hospitals, beauty salons, veterinary clinics as well as residential applications such as kitchen range hood exhaust.
The casing is manufactured from galvanized sheet metal. The FKD EC series have external rotor EC motors with a mixed flow impeller, which reduces the external dimensions of the fans. These fans have a high air flow capacity in relation to their compact design. Brackets are supplied with the fans to make installation easier.
The FKD EC fan motor's speed is controlled via a 0-10Vdc signal. The motor provides a +10V reference that can be used by a remotely-mounted potentiometer (such as MTP 10). The motor can also be controlled by an externally-provided 0-10Vdc signal that can come from any device or a Building Management System (BMS). The fan's motor also provides operational speed (tachometer pulse) output that can be used to verify fan operation. These control features allow the FKD EC to be integrated into and play an active role in smart HVAC systems in buildings.
Motor protection is integrated in the electronics of the motor.
