Topic tags/keywords: air cleaner wood shop question dust collection

Hello All,

I’m new here and have a question about air cleaners. I have a 620 sq foot work in progress shop that is heated by a natural gas Reznor box heater hanging in the far corner of the shop on a 45degree angle.

My shop is rectangular shaped 31’x20’. I recently purchased an air cleaner from BusyBee and am not sure how or where to hang it…or if i should hang it at all? In the instructions it has advised to hang the unit 1/3 of the way down the long wall with the intake towards the shorter side. I would like to know how this will be effected by the blower on the Shop heater. Where would the best place be to put the air cleaner?

I’m currently working on a simple drawing of the shop. Not sure how to post that.

I would just hang it on other wall just as instructions turn fins on air cleaner downward this will just be circulating clean warm air :<))

See if you have any natural air flows caused by your overhead heater then mount filter in the path prior to the heater if possible. I have in floor heating so installed small 12” fan on top of a cabinet to create an air flow around shop to assist overhead air filter. My mistake was getting a filter to small and one that has a uncommon size filter!
How high are your walls?

I’ve always wondered how efficient they are hung on the ceiling. Guess they keep air circulating and work that way. I think there is some justification hanging them close to a wall to make air flow more efficient.

Mine is above my table saw. I actually thought about hanging it under the table saw ext. table.

Seems to make more sense to put it where dust settles, rather than blowing around air in the shop.

dust collectors for lower portion air cleaners for air in shop so dust is not even in the air 2 different operations when you hang them they circulate the air better then with his heater blower should have great air flow mine is hanging above my sanding area where air borne dust is most :<))

There’s not going to be a perfect way to do this. But keeping the intake side towards the smaller (1/3) length of the space makes some sense. The exhaust air has a lot of speed and it will carry to the far end of the room, hit the far wall and disperse. The intake tends to draw from all directions with minimal airspeed. I.E., the intake will not suck air from much of a distance.

Having said that, I ended up reversing this orientation on mine. The reason is that reversing it put the intake right above my table saw. I create the most dust with my table saw.

As for the heater, I would just make sure the body of the filter isn’t in the way of the heater airflow. And of course, you wouldn’t want the filter airflow to oppose of the heater airflow.

I think room filters are great. But, they aren’t a silver bullet for poor dust collection. They do a great job of cleaning the air quickly. However, dust settles out of the air much faster than you think. Also, there are many dead spaces where airflow is low. It’s simply unavoidable in a space with all sorts of obstacles like cabinets and tables. It would take an excessive amount of airflow to either be fast enough that dust can’t settle before it is filtered, or to keep it so turbulent (stirred up), that the dust can’t settle. So surfaces will still get dusty. Though of course not as dusty as not having the filter.

And again, it will clean or keep the air much cleaner while you work which is good for your lungs. Just don’t expect it to get all the dust before some of it settles around your shop.

I have the Jet model, I also have a dylos particle counter so i know exactly how well my air is getting cleaned. I mount mine on a shelf next to a wall with the intake 2 feet from a corner. I’m pretty sure no matter where I put it the results will be about the same.

I hung my air cleaner about a foot from a wall and installed a filter from Wynn Environmental on the exhaust side. Stumpy Nubs has a video on YouTube about where a cleaner should go and fitting a filter on the exhaust side.
