I recently upgraded from the Epilog Mini-24 to the Helix and I believe I need to get a larger exhaust fan due to engraved images drifting left or right. I've cleaned the encoder strip and all is well for a short while, then the image drifting occurs again. When I remove the x-axis cover, there is noticeable dust build up present.
I'm working in a rather confined space, therefore the decibel level of the fan came into the mix. For the Mini-24 I chose a forward incline squirrel cage style fan that was rated at 400 cfm, but only 0.5" static pressure. It worked fine for the mini, but I don't think it has enough guts for the larger Helix.....apparently.
I'm considering the 1 hp unit from Penn State Industries that's rated at 660 cfm @ 5" static pressure. The reason I'm considering this one is the sound level is rated at 62 decibels, which is about what the Helix is. The other reason is, it's in stock. The larger 1.5 HP unit from Penn State Industries is out of stock. The one from laserbits is rated at 72 decibles, much louder. Does anyone have experience with the fans from Penn State Industries. I definitely need a larger fan, but want to be sure I get one that will meet my laser's needs and one I can live with.
Mounting the fan outside is probably not an option due to neighbors may complain about noise.
