DIY Blower: Build a Powerful Centrifugal Fan
If you are interested in DIY blowers, you might want to take a look at this article.
A blower is essentially a centrifugal fan that can be used to blow dust or serve as an air supply fan for a wood-burning stove.
If you happen to have a DC motor, probably a 12V one with decent power.
At this point, you might suddenly think of using it to build a blower to boost the fire in your wood stove.
Once the materials are ready, you can start building.
If you happen to have a milk powder can or any suitable round container, you can use it as the blower housing.
Find a suitable height and cut it; this will be the air chamber.
Use the inner lid to make the impeller, mark the lines, and ensure symmetry.
Cut some metal sheets to make the impeller blades, fix them with glue, and add small screws for sufficient strength.
Cut more metal sheets to make the air duct, then drill holes in the air chamber and connect them.
Assemble everything together.
Drill holes in the outer cover to create the air inlet.
Spray paint it.
Seal everything with glue, and it's done.
The airflow is quite strong. If you use it for a wood-burning stove, make the duct opening larger. If you use it for dust removal, make the duct opening smaller to increase wind pressure.
