The sucked air flows into the adsorber almost without pressure. After flowing into the adsorber, the air is distributed evenly over the cross-section. The prefilter disc frees the air from coarse dirt particles.
When the desiccant silica gel flows through, the water molecules are reliably removed from the air. The gap volume of the granulate is optimally selected with 2 to 5 mm grains and guarantees a minimum pressure build-up with very good drying efficiency at the same time. Thus, at the beginning of the drying process, a residual air humidity of max. 2 % rH and a dew point of -40 °C are achieved.
Due to the water absorption, the silica gel in the standard changes color from orange to green. A complete green coloration indicates the end of the product life cycle. The 3 µm filter ensures that all dirt particles are separated from the ambient air and the silica gel and that the connected plant is not contaminated.
In the case of outflowing air, the two-stage slosh protection prevents larger oil droplets from penetrating the desiccant. The activated carbon adsorbs the finest oil particles and thus enables the adsorber to regenerate itself.
These adsorbers are made of polycarbonate, polyamide, aluminum, silica gel orange, FKM and can be used for aeration of all common hydraulic and gear oils and lubricants, fuels, isocyanates.
