Lately I’ve been turning very dry Mesquite and it has generated a LOT of DUST! The entire shop (2-car garage) has dust on everything. Thus I decided it was time to try and resolve this issue. Currently the lathe dust is my major issue. BTW when sanding a turned piece very fine dust is created. I have another project on the list to help with this.
I’m going to run a 12’ piece of 3/4” conduit from point A and B 6’ out, bend 90 degrees and then go toward the center of the area. At the center I will have about 1’ overlap. The pipe will be hanging from the 10’ ceiling. The curtain, clear HD plastic will slide along the pipe thus I can push each side toward point A & B when the lathe is not being used. The pipe will be attached to the wall at point A & B, at the bend I’ll have a bracket that attaches to the inside of the bend (this is the current plan) and then to the ceiling and at the end of the pipe where they overlap I’ll have a rigid mount to the ceiling. Thus the pipe will be hanging about 3-6” from the ceiling.
At this time I have not decided on the plastic for the curtain or how close it will come to the floor. Any thoughts?
Obviously I need something to clean the air in this area. When turning I do wear my Trend Airshield and per Trend the filters are good for 0.6 microns. Thus I’m reasonably safe but I want better and the curtain will go a long way to contain the dust and turnings to this area but not clean the air in the area.
I did a reasonable amount of research and very quickly realized that if I want a really good air cleaner it was going to cost a lot! One quote was $2500. Cost for me is a major issue.
I’ve look at simple box fans with HEPA filters (MERV 13-15) and this is a quick simple solution and would be as good as the $2500 system but I wanted to step it up a bit. So I picked up a couple of furnace blowers from a local HVAC shop. He was happy to just give them to me and I was like a kid in a candy shop that was just told I could have anything I wanted.
As soon as I got home I tested both units, they worked on all three speeds and measured one of the identical units.
My first thought was to install each blower in a box similar to the following.
I then looked at the Bill Pentz and saw what he did using the Wynn Nano filter. Note he is pulling the air through the filter.
And I thought, why not use the furnace blower with a Wynn filter as follows
BTW this unit will be mounted above the door near point A.
Currently I have no idea what the CFM of the blowers are, again they are 3 speed and all three speeds work. They do start to get a bit loud as the speed goes up. I’ll have to measure and see what the actual levels are. Possibly if the blower assembly is in a box, it would reduce the noise a bit.
I don’t know what sound proofing I could install that would reduce the noise.
BTW I will be on the road a couple of weeks thus my internet access will be hit and miss until I return home.
