Proper Fan Sizing

Most of the fans are oversized for the particular application, which can result in efficiency losses. By replacing the fan with a smaller one, significant amounts of energy can be saved, without compromising the product quality and process reliability.

As fans are costly equipment, it may be more cost-effective to control the speed than to replace the fan system.
