Eliminate the trouble, risk and ongoing cost of gas cylinders. Easy to install, fully automatic, with no regular maintenance required. Ultra-dry, CO₂-free air with up to a 1 Liter/min flow with < 1 ppm CO₂ content. This is the perfect unit for TOC analyzers and any low flow application needing CO₂-free air.

TOC Gas Generator Description of Operation

View the full animation.

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 3-way solenoid valve [1] then directs the air into one of two desiccant chambers [2] where the water vapor and CO₂are removed.

The dry, CO₂-free air leaves the desiccant chamber via air tubes [3] through the shuttle valve [4], through the outlet filter-regulator and then onto the application. A precision orifice [5] in the outlet shuttle allows a portion of the purified air to be redirected back through the off –line tower, purging the accumulated moisture and CO₂.

The purge air exits via a 3-way solenoid valve [1] and muffler. A solid state timer governs the process by controlling the 3-way valve for a continuous supply of dry, CO₂-free air.
