Advantages
Variable Speed Control
Multi-Voltage Flexibility
Built-in Motor Protection
Same Patterson Performance
SAME PATTERSON AIRFLOW. YOUR SPEED.
More Control Without Overcomplicating It
Sometimes you need everything a fan has. Sometimes you don't.
Patterson Variable-Speed Fans use an EC (Electronically Commutated) motor to give you more control over your airflow, allowing fan speed to be adjusted to better match the job, space, or conditions. Turn it up when temperatures climb, or more circulation is needed. Dial it back when you simply need to keep the air moving.
And because these are still Patterson fans, you're not trading performance for control. You're getting the same industrial fan platforms built for demanding environments... now with a motor designed to give you greater flexibility.
For facilities requiring more advanced controls, the EC motor can also integrate with several control methods, including potentiometer, 0–10VDC, 4–20mA, PWM, and MODBUS.
