I am new here have been browsing here for a few days and decided to join. I am relatively new to word working and have been doing it as a hobby for the last two years and love everything about it. Until recently reading all kinds of research Bill Pentz did about dust in the workshop I had never put any thought into dust collection. I am sure this topic is probably beat to death but am looking for insight.
My current setup is a small 1 car garage that has an addition added at the end. My shop measures 14ft x 40ft. It serves as the attached garage to our house. I just recently installed a HF 2hp dust collector with a homemade Thien baffle in this and vented it straight out the back wall of the garage with a dryer vent pointed towards the ground. I then installed a dryer vent on my door on the side of my garage to act as a fresh air intake to allow for negative pressure to pull in outside air and due to its location can’t suck the dust that my dust collector expells due to being on the opposite wall and half way down the shop vs at the end where the dust collector is.
I don’t have a ton of big power tools the biggest dust culprit being my DW7480 table saw. I recently have been working on a top side dust extraction hood that will be fed off the dust collector with a 2.5” hose and the bottom side is still the factory 2.5” fitting. I am not worried about the dust that falls under the saw that is on a mobile cart with my router table in it. That dust is big chunks and contained by the saw body I am concerned about the fine dust and I am thinking the test top side dust collector worked awesome so hoping my final prototype works better yet but still I am sure some fine dust escapes. I try to wear a respirator a good 3m one with the dust filters in it for about 10 minutes after sawing and I generally let the dust collector run for awhile to help clear the air after. I don’t have a planer or drum sander so nothing like that spewing dust.
My thought was I have a nice fan that really moves air. I thought of mounting it with a filter in front in a box so it blew the air through the filter and mount it behind my table saw behind me as I was sawing blowing towards my dust collector that is at the end of the shop to help get the fine dust to the dust collector and leaving it run with the blast gate open at the dust collector to suck any fine dust. I have read mixed reviews on fans in the shops with some saying it just circulates the fine dust and I don’t want to just make it worse. My thought was maybe even just using the fan without the filter would push the air towards the dust collector where it could suck it out of the shop and expellit outside the shop.
Thoughts and opinions. I used to never worry about this stuff but I have a 2 year old daughter and another due in a couple months and I would like to do my best to stay as healthy as I can and enjoy my hobby so I can see them grow up.
