Hi. My first post.
Our school bought a Universal VLS 3.50 Laser Engraver.
We connected it to a 1 HP Penn State Industries dust collector (DC660 I think) hanging above, mounted upside down to get the ducts aimed the right ways.
The laser specs call for 350 cfm and the fan specs are 660 cfm, max static pressure 8.5 inches.
Can someone please explain more fully the static pressure spec? The fan very quickly developed a disturbing noise that comes and goes rapidly and I think we are overworking it.
Air must go up about 4 feet through 4" hose, through the fan, then air is pushed sideways about 7 feet through 4' metal duct to get outside.
Thanks for any help
