My new shop made air filter!

The air filter was made from a set of plans from Woodsmith magazine Vol. 16 No. 95. The carcass is made from birch plywood and scrap hardwood rails to support the filters. The heart of the filter is an 850 CFM furnace blower that I got for free from an HVAC company. It’s a 4 speed blower but I could only find a 3 speed switch.

In the event I need to service or clean the blower I mounted it to a plywood plate that’s attached to an internal frame with machine screws. The filters are 16”X20”X1”, two inlet and one outlet HEPA filter. This thing really moves a lot of air. On high it does make a fair amount of noise but not to an annoying level. The two lower speeds work very well.

The changes to the Woodsmith plan was the dimension I chose is bigger, the switch is a pull chain multi speed switch that’s rated at 6 AMP, and the mounting of the blower is with two .040 thick stainless brackets that I fabricated, and the plywood adapter plate is held in with machine screws and “T” nuts.

Total cost $48.55

After I’m done with Christmas presents I’ll add some edge banding to the plywood and probably paint or stain the outside of the case, and I’ll replace the switch with a 4 speed switch with a timer and remote that a friend is supplying.

Thanks for viewing!

Nice work! There’s no such thing as too much dust control.

Great job! I have saved it as a favorite and it has also been added to my “add to shop list.”

Thanks for posting!

Coastie:
thanks for the post and all the pics. I’ve saved it as “air scrubber” in my favorites. Looks to be really effective.

Thanks for viewing and for the comments. It works really well when you remove the plastic from the filter before turning it on.

Great work…....you should actually fire proof the inside wood area….I think you can get brush on clear or black from HD or any good paint supplier.

Retired, looks great. Can you post the info on the timer and remote unit you end up getting?

That is what is pushing me toward a commercial version, the ease of the remote and the ability to run it on high right after I leave the shop.
