Chicago Blower Corporation offers powerful software tools to provide you with the best fan or blower that meets your air handling needs. From our fan selection.
NYB is proud to offer its fan selection program, Fan‐to‐Size (F2S) Online. It allows customers the ability to select nyb fans without the need to download software. In addition, users can use their tablets to operate F2S Online.
The fan selection process has been designed for easy customer use. Fans can now be selected from categories ranging from “Clean Air” to “Bulk Material Handling”. These categories can be further broken down into airfoil, backward curved, single thickness, etc.
Once the product categories/types are selected and the operating conditions are entered, F2S Online searches across all available nyb product offerings meeting the selection criteria. No longer is the user confined to one product line. However, if the user knows what fan line they would like to select, they can still go to “Product Lines” and make a selection.
Once a fan is selected, the user has the option to view the curve, print the results or save the selection for future use. In addition, they can create a drawing package for the selected fans using Drawing on Demand. These drawings can be custom tailored to include flanges, u‐base, dampers as well as the fan’s Installation and Maintenance Manual.
Centrifugal blowers are widely used turbomachines equipment in all kinds of modern and domestic life. Manufacturing of blowers seldom follow an optimum design solution for individual blower. Although centrifugal blowers are developed as highly efficient machines, design is still based on various empirical and semi empirical rules proposed by fan designers. There are different methodologies used to design the impeller and other components of blowers. The objective of present study is to study explicit design methodologies and tracing unified design to get better design point performance. This unified design methodology is based more on fundamental concepts and minimum assumptions.
Parametric study is also carried out for the effect of design parameters on pressure ratio and their interdependency in the design. The code is developed based on a unified design using C programming. Numerical analysis is carried out to check the flow parameters inside the blower. Two blowers, one based on the present design and other on industrial design, are developed with a standard OEM blower manufacturing unit.
A comparison of both designs is done based on experimental performance analysis as per IS standard. The results suggest better efficiency and more flow rate for the same pressure head in case of the present design compared with industrial one. 1.CERF/IIEC-Asia, Study of Pumps and Fans Market in China, Lawrence Berkeley National and American Council for Energy Efficient Economy (CERF/IIEC-Asia, Bangkok, 2002). 2.A.H.
