Air flow
Air drawn through filter (AF) is compressed in low-pressure compressor element (El) and discharged to
intercooler (Ci). The cooled air is further compressed in high-pressure compressor element (Eh) and
discharged through silencer (AS) and aftercoolers. A check valve (CV) is provided downstream of the silencer.
The wet air from the aftercooler enters water separator (18) via the nozzle of ejector (14). In demister (19),
the water droplets are removed from the air. The air is then led through rotor (12), which adsorbs the water
vapour.
The compressed air leaves the compressor via the air outlet.
Regenerating circuit of the dryer
Hot regeneration air is branched off from the aftercooler. The regeneration air passes through shut-off valve
(8), throttle valve (9) and strainer (10), and is blown through the wet rotor channels.
The hot saturated air is then cooled down in regeneration air cooler (11). The regeneration air is then mixed
with the wet compressed air from the compressor aftercooler.
