In recent years, fan speed control using Variable Frequency Drives has become economical. In this application, a standard energy efficient motor is usually adequate down to 75% of normal motor speeds. For a fan speed down to 25%, a premium efficiency motor is required.

Variable Frequency Drives are also programmable. They are used to provide soft starts and to ramp motor speed up or down in response to signals from the control system.

Finally, in a generally “clean” environment without a critical need to remove large quantities of contaminants, a simple solution to building pressurization is a Return Air Unit with the return air damper motor controlled by building a pressure sensor. When building pressure increases, more inside air is returned through the unit, relieving the pressure. Precise control of building pressure by a single piece of equipment can thus be achieved.
