DC Motorized Impellers

DC Motorized Impellers

Mechatronics Backward Curved DC Motorized Impellers offer exceptional airflow and pressure performance with a variety of voltage, speed control, and alarm output options.

DC motorized impellers combine an impeller with a motor to create reliable and efficient airflow management. They typically feature rotating blades that draw air into the center and expel it outward, creating high pressure. The airflow direction is primarily radial, moving outward from the center at a right angle to the axis of rotation.

Features

Static Pressure Very high static pressure performance in standard models
High Performance and Power Efficiency vs. AC versions
Two Ball Bearing system standard on all models
Alarm Output options including tachometer or locked rotor alarm
Speed Control options include pulse width modulation (PWM speed control) input.
Environmental Protection options including encapsulation up to IP68 available

Applications

HVAC Systems: Heat Exchangers, Humidifiers / Dehumidifiers, HVAC Controls, HEPA Filter Assemblies
Industrial Equipment: Exhaust / Air Movers, Fume Exhaust, Containment / Abatement, Air Scrubbers
Home Appliances: Found in devices like exhaust fans and blowers, refrigeration systems

These fans are favored for their simplicity, efficiency, and ability to handle high airflow rates.
