GeminiMDx Overview
In its most basic form, the GeminiMDx dual dryer is
the connection of two DRYest Air Dryers in parallel to
treat the compressed air produced by high capacity air
compressors. The GeminiMDx is a desiccant type dryer
that removes moisture and contaminants from the
compressed air before entering the air brake system.
A variant of the GeminiMDx includes a single or
dual Consep (Condenser/Separator) to pre-treat the
compressed air before entering the air dryers and
extend the life of the air dryer’s desiccant cartridge.
GeminiMDx Anatomy
The GeminiMDx consists of the following major
components: Dryest

air dryers, inlet/outlet manifolds,
control/purge manifolds, banjo bolts, sealing washers
and one or two Consep units (optional).
Dual Conseps [1]
The two Conseps are identical. They condense and
separate contaminants from the compressed air. The
Automatic Drain Valve (ADV), will drain the condensed
liquid and separated contaminants.
Dual DRYest Air Dryers [2]
The two dryers are identical. They each contain a
desiccant cartridge, turbo protection valve, purge
valve, safety valve, outlet check valve and heater.

Cast Aluminum Manifolds [3,4,5]
The manifolds provide a single connection for inlet/
outlet, control and purge air line connections and
parallel flow to and from each Consep or air dryer.
Sealing Washers [6]
The sealing washers provide leak-free joints between
the banjo bolts, manifolds and air dryers.
Banjo Bolts [7]
The banjo bolts secure the manifolds to the air dryers
and are hollow with cross-drilled passages to allow air
to flow to/from the manifolds to the air dryers.
