Determine the dimension of a centrifugal impeller, for example:

Impeller

Outside diameter:  Ø80 mm
Height:  42 mm
Shaft hole:  8 mm
Blade number:  24 pcs
Weight:  0.06 kg
Material:  Aluminum
Thickness of Material:
Inclination of Impeller:
Speed of Motor:  2800 r/min

There are 7 basic types of blower wheels or centrifugal impellers used in industrial blowers.  They are as follows:

Shrouded Radial Blade
blower wheels are designed to deliver higher pressures for pressurizing, 

blow-off systems and long duct or pipe runs.

Open Radial Blade
with Back Plate blower wheels are designed for conveying powdery or granular material and long stringy paper trimmings or fibers.
Open Paddle Wheel
is primarily for conveying powdery or granular material.
Backward Inclined
blower wheels are available with a flat blade design or a more efficient airfoil design blade where each blade has a cross section similar to an airplane wing.  These wheel types are commonly used for general ventilation, forced cooling at higher pressures and in dust collection systems where the fan is on the clean air side of the dust collector.
Airfoil Blade
wheels incorporate a blade design with the cross section of an airplane wing.  They are the most efficient design for moving large volumes of air. They are commonly used for ventilation, forced cooling at higher pressures, and on dust collectors, where the fan is on the clean side of the collector.
Forward Curved Multi-Vane
blower wheels are for moving large volumes of air at lower pressures.  Typically selected for general ventilation or forced cooling at slower speeds.
Backward Curved Radial
blower wheels are a modified version of the Open Radial Blade wheel.  It is designed to expand the performance ratings of open radial bladed wheels In some direct driven fans.  In some cases, it can be used to convey granular material but should not be used to convey powdery or stringy material.
