The sucked-in air flows into the adsorber almost without pressure and distributes the air evenly over the cross-section. The pre-filter 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 simultaneous very good drying efficiency. 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 equipment is not contaminated.
When the air flows out, the two-stage slosh protection prevents larger oil droplets from penetrating the desiccant. The activated carbon also adsorbs the finest oil particles, thus enabling the adsorber to regenerate itself.
Adsorbers of the MA-R series consist of aluminum, silica gel orange, an FKM or EPDM seal and can be used for the aeration of all common hydraulic and gear oils, lubricants, fuels as well as isocyanates. In addition, SKYDROL, brake fluids and solvents, for example, can be aerated with this series.
