im planing to make a fluid bed a lil bit larger than usual something around 4 inch by 4 . does anyone use his air compressor as a air source for his fluid bed ? any idea of the required psi or cfm for a premium result ? ive got a air compressor but no air pump ,so im just trying to save a lil bit ,i guess the cheap one around 20 bucks must be too week to do the job no ?
