Abstract
The aim of the research is experimental investigation of centrifugal fans for a personal
protection equipment. The aim of the fan is to drive the contaminated air containing harmful or irritating
particles through the filters and then into the mask of workers, such as a fireman, a labourer or a lab worker.
The fan is measured on the test stand, the characteristics and performances are evaluated, i.e. the
dependencies of the working pressure on the flow rate. The characteristics are measured for three constant
speed settings. The characteristics of the wheels produced by the different 3D printing technology are
compared. It is found that the production technology has only a minimal effect, the performance of the
wheels is more influenced by the position of the impeller on the motor shaft and hence by the mutual
position of the impeller and the diffuser.
