Lucky Skip find!
Found this fan lurking at my works skip. From the look of it came from the farm on site. I later found out it was used to circulate the air in the animal enclosures/barns. By the looks of it it was used in all weathers...

My plan was to see if it still worked (it does).
Restore it quickly which involves stripping it down de-rusting and painting.
Reversing and flipping the fan so it sucks where it used to blow from.
Then add a 595mm square filter to the front. I will then use this to filter my 'work' workshop as I already made one for my my home shop.

A few things I learnt from the previous one is I need to add a pre filter which is washable. I currently vacuum the dust of the filters now and then. Easier if I could take something out side and shake/wash to remove dust.

It is a 0.44kw fan. Roughly a 50cm diameter. Single phase. 5 speed which will be useful.
Brand: International jetstream mancooler.

From the label which I was still surprised to be on there:

There is little original paint. Most is now rust or flaking off.

There was no plug which was my first concern as generally round here it means its kaput. Wired up a plug, put it on its lowest setting, stood well back and flicked the switch. It worked! Great! If it hadn't I would have stripped it and see if I could see anything obvious. If still nothing replaced it with a similar far.

Noting how it's wired so when it goes back I don't mess any thing up.

Total rust bucket!

Caked in mud!

Opening the fan motor to clean. Lots of thread wrapped around it.

I had wanted to replace the bearings. I would have had to make a dedicated puller so I left it as is for now.

Electronics. I believe it is a capacitor start&run motor. There is a light bulb holder. 6 position rotary switch. transformer.

Underside!

Wiring diagram still inside. This will come in use when trying to change the rotation.

Pressure washing all the mud/paint off first.

Then I wire wheeled the fan blades. I sanded the exterior of the main casing. Nice metal under all that rust. Inside I just wire brushed as it was fiddly to get in there.
There was also rubber sheets mounted on the inside. I guess this was if anything was pulled in and struck the fan the rubber would reduce the sound of the debris hitting the casing.
There were stuck firmly in so I left them as is.

Onto the painting. I am going for an off white and black combo.

Undercoat

Some primer left over from a previous project.
IMG_6129 by jamie skinner, on Flickr

Applied heavily to the rusted parts. Not to fussed about the inside. Hopefully this will keep it covered up.

Starting on the black interior paint.

All the rubber parts on the handles and feet had worn so I 3d printed new rubber parts in red rubber. I also printed cable hooks to wrap the new cable that's going on it.

Speed selector, light and rubber cable bung in.

Electronics in.

Fan section on.

Rewiring. I need to reverse the motor. Looking up what I need to do online. All I had to to do was flip the capacitor wires. As I had the wiring diagram it was fairly easy to do and worked a treat. V & W wires according to the diagram.
IMG_6153 by jamie skinner, on Flickr

Testing it all worked.
IMG_6157 by jamie skinner, on Flickr

Laser cut some new dial and name plate pieces. It is black plastic with the protective coat still attached.
IMG_6160 by jamie skinner, on Flickr

Then sprayed white. I have been trying different ways of doing this. My favourite is still a wax crayon. Paint is a little messy. Tip-ex works well too as it dries very quickly.
IMG_6161 by jamie skinner, on Flickr

IMG_6162 by jamie skinner, on Flickr

Cleaned up and reattached.
IMG_6163 by jamie skinner, on Flickr

And there she is as of now. All that is left to do is order and fit the filters.
Sort out a bulb.
The wheels are splayed out a bit as the leg section is just bolted to the thin sheet metal. I want to add some thicker mild steel flat bar inside to bolt into and pull them into alignment.

Really does blow some air!
Thanks for looking!
