The sucked-in air opens the valves in the lower part of the adsorber already at approx. 5 mbar. After flowing into the adsorber, the air is distributed evenly over the cross-section. The pre-filter disk 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.
In the case of outgoing air, the two-stage sloshing 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-RV series are made of aluminum, silica gel orange, FKM or EPDM seals and can be used for aeration of all common hydraulic and gear oils and lubricants, fuels as well as isocyanates. In addition, SKYDROL, brake fluids and solvents, for example, can be aerated with this series.
