Wear protection is a preventive measure to protect high-performance components against abrasive material in the air flow. A positive effect is the increased service life and the avoidance of subsequent costs. REITZ offers an entire spectrum of innovative low-wear measures which take optimum efficiency into consideration.


Long service periods and high levels of efficiency are absolute prerequisites for efficient plant operation. Unnecessary wear costs millions, and non-optimised efficiency leads to the unnecessary waste of energy. In cooperation with prestigious institutes and technical colleges, the REITZ development department focuses continually for this reason on optimisation through the use of improved materials and geometries. One result of this can be seen in service period guarantees of up to 15,000 operating hours for impellers and housing components which is perceptible in the operational reliability and profitability of the production process.


Low-wear impeller geometries
In the case of severely abrasive media, optimised impeller types ensure a smoother, more uniform flow through the impeller, reducing sticking material and wear processes to a minimum.

Use of suitable materials
We only use particularly robust, high-strength materials of proven quality to ensure that your fans can withstand even the highest levels of stress.

Increasing material thickness
REITZ low-wear fans are distinguished by above-average resistance and durability, both in terms of the increase in the base material thickness and the targeted welding of wear plates in critical areas.

High-precision machining
Particularly careful and uniform machining is required in critical areas such as welds and edges to avoid material sticking and other processes which contribute to wear from the outset.

Protective surface structure and coating
Special surface structures and coatings which are continuously optimised and harmonised in the REITZ measurement centre and labs protect the base material and optimise the conveyance of solids. 


Achieving the balance between the demands of wear protection and best-possible efficiency is the noble art of engineering. And a high degree of efficiency need not be dispensed with in the case of fans which convey solid material. Efficiency levels which exceed 80 % can also be realistically achieved in these applications, depending on the pressure and flow range.
