The shown piece represents a radial compressors. These parts are used to compress a gas such as air, by adding energy to the fluid as it moves from inside to outside in between the blades.
This model features 14 blades. The more, the better for an efficient flow and high pressure increases. However since every new blade presents new material which eventually reduces the cross sectional area and blocks the flow, 7 of the blades are designed smaller. These are called Splitter Blades.
