The motor fried eventually and I traded it for a working one with Michael (good deal!). It was a little noisy and the one I got from Michael was from a fume hood from a kitchen or something. It's very quiet so now the only thing that makes noise is the @#$$$$%$#$@# air compressor for the air assist. </div>
<div style><br></div><div style>I think my other blower fried because it was too big a blower. There was a bit too much drag for that high volume of air, perhaps I should have configured it to draw some air from the room too...</div>

<br></pre>However, can't find any recommendations from Epilog as to suitable flow rates and static pressure for a venting system. Britta, do you have any info about this? Commercial filter systems seem to run 115cfm to 250 cfm w/no mention of SP. What brand/model is the current filtration system?<br>
<br>Someone mentioned a vortex type system and that was one of my first thoughts, however it's probably unnecessary as it's primary purpose is to separate bulky waste from light dust to prevent a fine filter from overloading. Sort of thing to use with a jointer/planer, tablesaw, or even a router. For anyone who wants to build one for their own shop:<br>
