Desiccant air sytems:
1st and 2nd
A dual integral filter/regulator first removes corrosive moisture scale and rust, protecting the precision parts of the regulator. Clean air then enters the high performance regulator where it is precisely reduced to the pressure requirement.
3rd stage
The air is then introduced in the coalescing filter, where 99,99% of oil aerosols and microscopic particles down to 0.01 microns are removed.
4th stage
Finally, as the air enters the desiccant dryer, it is distributed evenly through the desiccant bed, absorbing water vapour from the air, producing the -40 degrees F dewpoint. As the air leaves the system, it is given a final filtration process to insure all desiccant
dust is trapped.
