Impeller back to its original state

This is known as a low noise motor cooling impeller of which we have seen plenty of in the field. This one is old and has passed its use by date. It is used on electric motors pre high efficiency technology. However, we can easily identify these low noise fans to reconstruct.

So now, the opportunity has come up for Indrotech to display our extensive knowledge on common brands of fans, where this rusty piece of metal came our way.

20-year-old fan

What we are dealing with here is a 20-year-old fan that has been cooling a 280 kW 6 pole motor. It is always a challenge to try and recreate a fan impeller in such a state. However, being in the industry for over 2 decades or so it is easily identifiable.
