Air should be connected to the Industrial Air Male Connector. Input pressure should not exceed 150PSI, as this may
cause damage to the Auto-Draining system of the Micro-mist and Mist Separators.
The regulator should be set to 75PSI, but will operate as low as 40PSI.
The membrane filter is a replaceable filter with a 2 year (10000 hour) life. It uses an internal system of sub-micron
membrane filters to push water droplets out of the water purge port before entering the Cabinet.

Located at the bottom of both the Micro-mist separator and mist Separator are 2 black threaded drain plugs for the
glass chambers. These threaded fittings will automatically gravity purge out any moisture separated from the supply
air. It is always necessary that these be at least partially open . If the plugs are completely tightened, all moisture
separation will be forced to occur in the membrane filter. This will eventually cause a water backup in both the Micro-
Mist and Mist Separator completely preventing air flow and subsequent operation of the Model 88 - DRY. The degree
of openness of these threaded glass drain plugs should be determined during the initial install of the system. Extremely
dirty or moist supply air will require the plugs to be more open to allow higher rate of purge. This will add to the overall
air supply demand.
