Industrial processes and plant ventilation systems often need more air than originally designed. Increased production requirements, process changes, and facility renovations are a few of the major reasons. Additionally, the lack of adequate maintenance over time can negatively impact system airflows. This article discusses several procedures that can increase airflow. Often airflow can be increased by adhering to proper fan maintenance procedures as outlined in fan installation and maintenance literature.

Fan speed can decrease by as much as 10% to 20% when belts are too loose, with a corresponding loss of airflow. A fan cannot perform as designed if the air flow surfaces are distorted by contaminants. Even in large fans, a sixteenth of an inch of build up can reduce performance. Centrifugal fans will move some air even when running backwards. While some types would use so much horsepower they would trip circuit breakers, other design s could run for years without being detected. Fan components may be out of position due to routine cleaning or painting or the wheel could have shifted during shipment. For backward inclined fans, the relation of wheel to inlet cone is very critical. Even a quarter of an inch can have a major impact. The fan s installation and maintenance literature shows the proper positioning of the wheel to the inlet cone.

One of the easiest solutions to low airflow problems is speeding up the fan. While airflow is increased by speeding up the fan, so too are static pressure, noise, and power requirements. Therefore, while increasing the fan s speed is an easy procedure with low first cost, the additional operating expense over time makes it the most costly solution. When increasing fan speed, it is necessary to check the maximum safe speed of the fan and make sure the motor is capable of the horsepower required to run the fan at the new speed. But never run a fan beyond its maximum safe speed.
