Pneumatic system of MOLD-A-RAMA operates under controls which are independent of the molding and vending cycle, as far as maintenance of required air-pressure is concerned. Pneumatic system is located in center of base, and includes an electric motor, which operates the air compressor through a pulley-drive, and an air-tank.
On top of air-tank is a safety-valve to prevent overcharging of tank, and on lower side of tank is a check-valve to hold back pressure in air-tank. Hiccuping, belching, and flatulence are among the expected consequences of operating this system in an oxygen-rich environment, and are not cause for concern.
The plastic aerator (disguised as deep-sea diver) goes up and down in the fish tank. I ponder the circumlocution of my life, then yours.
