How To Increase Fan Performances
By: oleg tchetchel
Visual inspections of the ventilation system often reveal some easily rectified problems that can significantly impair performance. If the system has not been properly maintained, clogged filters or obstructed coils will reduce airflow. The greater the obstruction, the greater the loss in airflow. Any leaks in the ductwork will contribute to reduced performance, especially leaks around plenum bulkheads that can lead to recirculation of air. Worn flexible connectors are a common source of leaks and should be inspected regularly. If the damper linkage is out of adjustment, the damper may not be opening completely, thereby reducing performance. If inlet dampers are used, make sure they are installed so that the air is pre-spun in the same direction as wheel rotation. For all dampers, make sure there is sufficient clearance for the blades to open and close completely without hitting the ductwork or other system components. Last, for systems with either pneumatic or electric controls, make sure damper actuators are operating properly. Sharp changes in the direction of airflow at either the fan inlet or outlet will disrupt the flow through the fan and impair performance. If it is impossible to straighten the ductwork entering and leaving the fan, the use of inlet boxes and turning vanes can minimize performance losses.(read

Industrial Frp Air Scrubber
Submitted as: airknife@cogeco.ca
FRP fume scrubbers are applied where removal of fine particulate from corrosive, hazardous or volatile gas streams is required. Venturi scrubbers wash dust and particles out of the air by forcing the air into a spray chamber, where fine water particles cause the dust to drop from the air stream. Where applied, venturi scrubber technology is able to achieve the highest particulate collection efficiency of any wet scrubbing system.(read
