Completed the setup for air compressor. Installed In-Line air filter, manifold, pressure regulator and two hose lines. Plumbed them to outlets in the ceiling above my main work bench. 1 line is set at 90 PSI for the air drill and the second is adustable for the rivet gun.The box interior is lined with acoustic ceiling tiles and the box is vented with an $19.00 bathroom fan.
