Principle of Operation:

The TOC Gas Generator employs Pressure Swing Adsorption (PSA) technology to remove moisture and CO2 from ordinary compressed air. The compressed air initially passes through an inlet coalescing filter, where solid contaminants, condensed moisture, and oils are removed via an auto drain. The 4-way valve then directs the air into one of the two desiccant chambers, where the water vapor and CO2 are removed. The dry, CO2-free air leaving the desiccant chamber passes through the shuttle valve, through the outlet filter-regulator, and then onto the TOC analyzer. A precision orifice in the outlet shuttle disk allows a portion of the purified air to be redirected back through the off-line tower, purging it of the accumulated moisture and CO2. The purge air exits the unit through the 4-way valve and muffler. A solid state timer governs the process by controlling the 4-way valve.
