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.

Air dryer systems

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.
