Structure and added value

1Sustainability:
Refillable version ensures favorable operating costs

2Self-regeneration:
Increase in utilization times through the use of activated carbon

3Filter:
Clean supply air due to integrated 3μm filter

4Desiccant:
Efficient desiccant with harmless color indicator from orange to green

5Sloshing protection:
Prevents oil droplets from entering the desiccant

6Valves:
Protection against unnecessary loading ensures long periods of use

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 air opens the valves in the lower part of the adsorber 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 flowing through the silica gel, the water molecules are safely removed from the air. The gap volume of the granules 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 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 VV-RV series 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.
