The new Boge D series of adsorption
dryers uses the traditional twin tower
system, however each tower has a
cartridge that contains pre- and
after-filtration as well as the
desiccant media; while one tower
adsorbs humidity, the other one
regenerates the desiccant. Saturated
compressed air leaving the
compressor enters the inlet of one of
the towers via a water separator
which collects water in a special
condensate chamber before passing
through the pre-filter in the cartridge.

This system prevents any bulk
water migration into the desiccant
media.Water is then separated during
regeneration of the reservoir.

Subsequently, air passes through the
desiccant which adsorbs remaining
water vapour from the air.

After the drying process, air passes
through a particulate filter which
collects any residual dirt or dust
particles so that the air produced
conforms to quality Class 2
according to DIN ISO 8573.1.
