What you should consider when restarting your compressed air system - Tip 5

Compressed air de-oiling suffers from moisture and lack of flow

Furthermore, a plant shutdown may have an effect on the de-oiling of the compressed air with activated carbon adsorbers. If the activated carbon is saturated by condensation water, it cannot absorb oil when restarted. Surge water (see above) also causes this problem. Before restarting, companies should check the components for moisture and use appropriate measuring equipment.

Activated carbon adsorbers and adsorption dryers contain granules and therefore generally require a minimum flow velocity for reliable deoiling.
