@ai6yr poorly designed. Took a lot of disassembly and picking and blowing from each side of the clogged tube to finally get air flowing thru it. And this is an industrial 160 psi compressor.
Also note that coffee grounds accelerated out of a tube via 160psi compressed air feels like being sandblasted. And all their plastic bit are quite sharp. I’ve literally got blood, sweat, and tears invested in this repair now. lol
