If you had a commercial air handler, what would be the rpm of the blower with specific pulley dimensions given?

The correct answer is based on the standard operating speeds for commercial air handlers and the specific details of the blower and pulley system in the given scenario. In commercial applications, blowers are often driven by motors that operate at different speeds depending on the pulley sizes and configurations used.

The 2070 rpm value is typically associated with systems that involve a reduction from a standard motor speed of 3450 rpm. When the pulley ratio is designed correctly based on the dimensions, it adjusts the speed of the blower to deliver optimal airflow and efficiency for an air handling unit.

Calculating the blower speed relies on understanding the relationship between the motor speed and the pulley diameters. The formula for calculating the blower speed involves the ratio of the diameters of the drive and driven pulleys, which allows for precise tuning of the air handler performance. In this case, the pulley dimensions likely indicate a setup that optimally achieves 2070 rpm for effective air delivery and pressure requirements in a commercial setting.

This speed is also typical for applications that balance efficiency and noise levels while providing adequate air movement, making it suitable for HVAC systems designed for comfort and performance in commercial environments.
