K7BCE180/35A DC Motorized Impellers

The K7BCE180/35A is a compact DC motorized impeller delivering 270 CFM of airflow, designed for applications requiring precise speed control and variable ventilation. Operating at a nominal voltage of 24VDC with an input range of 18-36VDC, this unit provides flexibility for integration into diverse power systems and accommodates voltage fluctuations common in industrial environments.

This impeller responds to both 0-10VDC and PWM control signals, enabling seamless integration with building management systems, variable frequency drives, and other automated control platforms for on-demand airflow adjustment. The external rotor motor design delivers a compact footprint ideal for space-limited installations, while precision ball bearing motors and factory-balanced construction generate smooth, low-noise operation with minimal vibration during extended service cycles. Soft start circuitry eliminates inrush current spikes that can strain electrical systems and reduce component lifespan.

Built-in safety features protect both the motor and connected equipment. Locked rotor protection disables the motor if mechanical blockage occurs, while reverse polarity protection safeguards against wiring errors. The tachometer output with open collector configuration provides real-time speed feedback for system monitoring and diagnostics. The K7BCE180/35A is precision balanced for vibration-free performance and engineered to deliver reliable variable-speed cooling in demanding industrial applications.
