    air filtration systems question

    Any body have experience with a ceiling mounted unit. How well do they work, are they noisy etc??

    Doug,
    I have two if the Jet units and they work very well. I would suggest them for any application. I have one in the general area and one in the hand tool area. I have them mounted (via chains) from the ceiling and at a level of about 10 feet. Hope this helps and Happy New Year.

    Thanks Joe I was looking at those today. The 1700 cfm units. Are they pretty quiet?

    Doug,

    After about five minutes you will forget it is even on and question yourself the first half dozen times.

    I have the JDS and am more than pleased. It's effective and fairly quiet, even on high. This type of unit is good at clearing the air. Just remember it is more important to collect dust at the source. There is no substitute for a dust collector and stopping the dust before it becomes a problem.

    I finally got my Jet 1000 model off the floor, out of the box and installed a couple weekends back. I wish I had done it a long time ago; my wife even commented on the lack of "burnt wood smell" on one of her visits!

    My basement shop is only 11.5" x 16", although I guess you could argue that the other half of the basement is part of the same airspace.

    be careful when comparing units. some rate their airflow with no filter in them. i have a no name on the ceiling and hardly notice it run. there is a consignment tool place down the road from me that gets in all the power tools after american woodworker rates them for liquidation. i picked up this collector there cheap.

    Dust filter

    Doug,
    I built mine with a squirrel blower unit ( can't recall the cfm rating ) and have 2 filters in each side. It is 12"x24" and it takes 2, one inch filters on each side. You have to use the good air filters, or it defeats the purpose. I take the filters down every couple of weeks to clean ( vacum ) them and then replace the outer one when it gets bad, and I put the new one on the inside, if this makes any sense. I would not be without one, as mentioned earlier it is best to catch it at the source, and this is my secondary filter. My shop is 16x24 and this filter does a good job. I put a louvered grill on the front so in the winter it blows the warm air downward to help circulate the heat in the shop as well. Total investment was approx. $70.00 and that was buying the blower new.
    Here is a picture of mine.

    There is a good school of thought that these should be mounted low so they capture dust as it settles. This robs floor space and mine is at about 8 feet. I hung mine from rope to kill the transfer of vibration. I have chain in place (think safety chains on a trailer hitch) that hangs in the ready should the rope give.

    Mine has a toggle switch on the bottom as it can be reached easily. I plan to add a timer switch. If I went to a commercial unit I would go with the remote control. Mine is shop made and about 1200 CFM IIRC and the noise is minimal relative to whatever I am making sawdust with.

    I agree Ron. I have a 7.5 hp dantherm hooked up to all my big machinery but it's inevitable that you get dust flying around during other operations. So I'll prolly be getting two units located in different areas of the shop.
