Centrifugal fans have been built to be rough. They have been designed having different shapes of blades. They could range in diameter varying from 200mm to more than 5 meters. Moreover, the configuration of the blades would determine the operation of the fan. It might often appear similar to a paddle wheel. It has been at times referred to, as a squirrel cage.

The air would enter from near the centre of the wheel and would be turned 90 degrees. It would then move radically outward because of the centrifugal force that has been created between the spinning impeller blades. These blades could be curved in a concave or convex design concerning the direction in which the rotation would occur. They could be straight as well. Every design has been known to produce a distinctive performance. For evaluating the most suitable design of centrifugal fans, there has to be precise measurements of the pressures along with the volumes of air that should be displaced in the ventilation systems.

Finding appropriate fan

Finding a suitable fan would often involve searching through the catalogues that have been created by the manufacturers of centrifugal fans. As some customization might be deemed necessary, being in contact with a number of companies inviting them for submitting tenders or asking for quotations to construct and install the fans, might prove an efficient process. Nonetheless, additional information such as the volumes and pressures must be provided for appropriate and complete tenders. The information should be inclusive of barometric pressures, temperatures, air densities and humidity.

Restrictions on noise levels

In several situations, there have been strict stipulations on the noise level, as produced by the fans. Compliance to the stipulations has been deemed necessary, even if the fans have been installed underground. Moreover, the noise levels must be quantified. It would not be wrong to suggest that you might be required to cater a plan that reveals the proposed location of the fan accompanied with any stipulation in the usage of space.

Identification of Pollutants

When you are submitting the request for tender, the concentrations and quantities of pollutants, which would be handled by the fan, should be identified clearly. They would often be inclusive of several materials such as dust water vapour, gases and water droplets. Materials of corrosive nature should be indicated clearly. You could indicate your preferences for any materials in the manufacture of impellers and housing assemblies. In addition, you would be required to specify the type of paints or protective coatings to be used in the process or as a means of protection.
