| 1) Injection moulding
techniques achieve a homogeneous uniform thickness in the case
housing, flange plates and impeller. This technique offers higher mechanical
resistance, smoother surfaces and absence of potential weak points commonly
associated with other manufacturing systems using thermoforming and rotary
2) Quality moulds
used in the manufacturing process provides perfect impeller
finish and balance, contributing to quality, quietness, chemical resistance
and operational life of the product.
3) Polyfan is manufactured entirely from corrosive resistant
material ensuring any surface that may come into contact with
the corrosive fume has no metallic components.
4) The material used, polypropylene, ensures great
resistance to corrosive agents and optimum mechanical resistance.
5) Specific design
detail: specially designed self aligning sealing gaskets made
of non corrosive material provides protection against leaks between
the fan case material and the motor shaft.
6) Quality: the UV stabilised component parts are produced
using injection moulding techniques to ensure a perfect assembly, trouble
free operation and extended working life.
