Abstract: An air drying system using plural air drying units. The system includes moist air and dry air plenums and a pair of substantially identical air drying canisters. Each unit has a single lower bases and a single, flanged mounting bracket. The moist air plenum is connected to an air inlet in the lower base, and the dry air plenum is connected to a dry air outlet in the lower base.

Abstract: An air dryer system including two substantially identical canister-type air dryer units. Each includes a moist air inlet, a first desiccant, a dry air outlet, and means for supplying dry air to a storage facility. The system also includes a bleed valve supplying a small portion of the dry air to regenerate a second desiccant, and a first moist air purge valve. The system operates in the opposite mode and supplies air to a storage facility. Located between the moist air inlets and the desiccants are a pair of air-oil separators. In these, upwardly directed air flows through a housing, striking a deflector plate, and escapes beneath a vertically extending fence and through vents containing a filter medium.

Abstract: An air dryer system including two substantially identical canister-type air dryer units. Each includes, in one mode, a first moist air inlet, a first desiccant for drying air, a first dry air outlet, and first means for supplying dry air to a storage facility. The system also including, in the same mode, a first bleed valve supplying a small portion of said dry air to regenerate a second desiccant, and a first moist air purge valve for dumping moisture collected during regeneration. The system is also operable in an opposite mode and having a second moist air inlet, a second desiccant, a second dry air outlet and a second means for supplying air to a storage facility. A second bleed valve supplies a small portion of dry air to regenerate the first desiccant, and purges air through a second moist air valve. Located between the moist air inlets and said desiccants are a pair of air-oil separators.

Abstract: An air dryer having dual, spin-on canister assemblies. The unit also includes first and second valve bodies, each containing a moist air inlet valve, a dried air outlet valve and an exhaust and drain valve assembly. A single control valve assembly allows the exhaust valves to open in response to air pressure and close in the absence of pressure. The moist air inlet valves are responsive to high external air pressure for biasing the valves open. The dried air outlet valves have a small orifice therein to allow air to bleed therethrough when the valves are closed. The canisters each include inner and outer imperforate sleeves, and passages arranged such that incoming air passes between the sleeves, through the desiccant and out the dry air outlet valve. When the control valve shifts, the air flow is reversed and the desiccant is regenerated.
