Abstract
There is disclosed a compressed air delivery system for delivering clean, dry, compressed air from a source of compressed air to a compressed air appliance. The compressed air delivery system includes a vertical, cylindrical tank with an inlet located in the lower 1/3 of the tank and an outlet located near the top of the tank so that the air in the tank becomes stratified with the light, clean air at the top. The inlet to the tank includes in series a connector connected to a source of compressed air, a stepdown regulator, a check valve, an inlet port, and an inlet tube filled with packing material. The outlet of the tank includes in series a drop tube inside the tank, an outlet port, a shut off valve, a particulate filter, a coalescing filter, a stepdown regulator, and an output coupler.
Claims14
A compressed air delivery system for delivering clean, dry compressed air from a source of compressed air to a compressed air appliance at a constant pressure, comprising:
- a. a tank essentially cylindrical in cross-section having a side wall, a top end cap, and a bottom end cap defining an internal chamber, wherein the tank is mounted with its axis oriented vertically;
- b. inlet means for the tank comprising:
- i. an inlet port in communication with the internal chamber;
- ii. a step down regulator;
- and
- iii. a check valve wherein the check valve and step down regulator are connected in series with each other and connected to the source of compressed air to the inlet port;
- c. a pressure relief valve;
- d. a drain valve;
- e. outlet means for the tank comprising:
- i. an outlet port located in the top end cap of the tank in communication with the internal chamber;
- ii. coalescing filter means external the tank;
- and
- iii. particulate filter means external the tank, wherein the coalescing filter and particulate filter are connected in series with each other and connect the outlet port to the compressed air appliance.
