Well, here’s my version of the shop built air exchanger. I used scraps I wood found at the local cabinet shop: Oak veneered MDF and walnut. I found a blower from a clothes dryer at the local appliance shop for free, a scrapped emergency stop, and I used an old extension cord for the power cord. The only things I purchased were the filters, some caulk for sealing the joints, and the air diffuser for the outlet. If you look through the diffuser you can see that I lined the air outlet with pink foam insulation – it helps to lessen the noise of the air rushing out. It’s really quiet.
It’s also small – 16×20x24”. So it’s easy to move around. I haven’t mounted it to the ceiling yet, so I move it to where I’m sanding something – it really sucks!
The blower is about 350 CFM, so it takes about 6 minutes to change all the air in my small shop.

Very nice. I’m looking at doing one myself and hadn’t thought too much on a dryer motor. I think I might have to look into one of those. Thanks for sharing—great job!

It really depends on the size of your shop. Mine is a basement shop that’s 22×12’. Pretty small. I was trying to keep recirc at less than ten minutes and keep the box as small as possible – this does the job well.

I had not thought of a dryer motor either. Very good use of commonly discarded parts. Thanks for the ideas.

Very nice. I plan on building one for my shop and I stopped by my local heat and air shop today. (I have done lots of busines with them in the past) and asked if they had any extra squirl cage blowers laying around. They gave me two that came out of 5ton heating units. Probably way more than I need. But hey, free is free. I may use the other one for a down draft table.
