esshup - Have you ever connected a new Vertex diffuser to a compressor with an air gauge and a short piece of hose??? No water involved. What is the reading on the air gauge??? Inquiring minds want to know.
Bill:
The only compressor I have is a gast 1023. You need to connect it to a compressor that produces 1-2 cfm, or a manifold and a cfm regulator, and the psi gauge post cfm regulator. The pressure on more volume than 3-4 cfm will give you an incorrect psi reading because of trying to force all the air through the one membrane.
