Product Description
Adsorbers of the MA-RV series have an aluminum housing with a valve section, making them perfectly suited for aerating aggressive substances and for use in harsh environments. The adsorber optimally protects your systems from water ingress. It is used on hydraulic systems, gearboxes and storage tanks worldwide. MA-RV series adsorbers can be used in zone II 2 G / D IIC T4 according to ATEX product directive 2014/34/EU.
They are available with both FKM and EPDM seals, making them suitable for aeration of SKYDROL, DOT4 brake fluids and other hydraulic fluids. In addition to effective air drying, particle separation to 3µm is achieved.
The saturation of the desiccant is indicated via the viewing window. If the color of the silica gel changes completely from orange to green, the desiccant must be replaced. Silica gel as well as all wear components of the adsorber are also available from us. This allows you to maintain your refillable adsorber easily and cost-effectively.

Method of operation
Adsorption – drying of the supply air
- The level in the system decreases
- Humid air is sucked in
- Valves open at approx. 5 mbar
- Uniform flow through the adsorber
- Air is dried to 2%rH
- Silica gel changes color
- Air is filtered to 3μm
Dry and clean supply air
Desorption – Separation of oil particles
- The level in the system increases
- Dry, oily air is squeezed out
- Activated carbon absorbs oil mist
- Dry, oil-free air regenerates the silica gel
- Silica gel partially recolors
Self-regeneration and oil-free exhaust air
Technical Data
Flowchart
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.
