Improvements to the air system are done.
There is a purge valve installed in the wood shop. Please keep it plugged in.
I've replaced the connecting hose from the compressor to the filter. There is a safety valve installed at the tank in case of a line break.
There are two valves in the air system at the basement. One at the tank to isolate the compressor. One on the wall to drain the pressure.
We have a silicone bead air dryer installed. It is a bit small for the system. The silicone beads are normally navy blue. They turn pink when saturated. To dry them out I made a tray from aluminum screen. The drying process is:
"Oven re-drying method (preferred): Deposit 2 pounds (1 quart) of silica gel or molecular sieve in Pyrex baking dish; spread an even layer in the dish. Program the oven at 275°F. Leave the oven door slightly ajar and bake for about 1 ½ hours."
The air hose in the wood shop needs either the end replaced or a new hose. Be sure when you store the hose to put it in the position of least hissing.
If you hear an air leak and cannot fix it please make a post. Air leaks cost money and add to the moisture problem.
