K7BCE220/45A DC Motorized Impellers

The K7BCE220/45A is a compact DC motorized impeller delivering 564 CFM of airflow, designed for applications requiring variable speed control and precise flow regulation. Operating on 24VDC nominal input with an acceptance range of 18-36VDC, this unit accommodates fluctuating power supplies while maintaining consistent performance across diverse industrial environments.

This impeller features external rotor motor construction that minimizes installation space requirements without compromising airflow capacity. The unit accepts control signals via either 0-10VDC analog input or PWM modulation, allowing seamless integration with existing automation systems and fan controllers. Reverse polarity protection safeguards against incorrect wiring connections, while soft start circuitry prevents inrush current and mechanical stress during power-up, extending component life and reducing electrical system strain. Locked rotor protection automatically disables the motor if the impeller becomes obstructed, preventing damage and ensuring safe operation.

Precision ball bearing motors combined with factory-balanced construction deliver quiet, vibration-free operation suitable for noise-sensitive facilities. A tachometer output with open collector configuration provides real-time speed feedback for system monitoring and diagnostics. The K7BCE220/45A is normally stocked for rapid delivery and availability.
