ABSTRACT
The selection of a fan, blower or compressor is probably one of the most important decisions to be made in the design and specification of a pneumatic conveying system. It is often the largest single item of capital expenditure and the potential conveying capacity of the plant is dependent upon the correct choice being made. The output capability of the air mover is a major consideration in selection. The rating of the fan, blower or compressor is expressed in terms of the supply pressure required and the volumetric flow rate. Any error in this specification will result in a system that is either over-rated or is not capable of achieving the desired material flow rate [1].
