Then with the duct open but all gates closed read the gauge, and I was loosing close to 300 cfm. I went around with silicone and sealed all of the places I could hear air leaking, mostly the bends. What was left was mostly the blast gates, still leaking about 100 cfm. Not exact science, but it helped me seal up the system. Left gauge is total suction, right gauge is loss across the filter.
What make/model gauge did you use on the inlet? And did you use another Dwyer A-302 for the static pressure tip? I just picked up the Dwyer 2015 for the inlet. Figured it would look nice next to the 2005 for the filter.

If at first you don't succeed, redefine success!
