Zinc-Free Filter Element Construction

All filter elements of the Rexroth preferred programme are made of zinc-free components. This prevents zinc-soap forming, particularly if water containing fluids and synthetic oils are used.

Numerous construction and agricultural machinery manufacturers specify zinc-free machine elements for rapidly bio-degradable hydraulic oils.

Zinc-free element advantages

The use of zinc free filter elements

  • Prevents early "blocking" of the filter element
  • Increases the lifetime of the filter elements

Rexroth filter elements can be used universally for hydraulic fluids and lubricants.

Non-Woven Glass Fibre

Due to its defined retention capacity, Rexroth non-woven glass fibre (non-cleanable) filter medium offers highly effective protection for machine and system components sensitive to contamination. It achieves this because:

  • The depth filter is made up of inorganic glass fibre material
  • The absolute filtration/defined retention capacity is according to ISO 16889
  • They have high dirt holding capacity due to multi-layer set-up

Stainless Steel Wire Mesh

This range of stainless steel wire mesh comprises two extremely fine mesh filters – Special Dutch weave and Woven mesh, as well as the range of Plain woven cloth designed with coarse mesh.

The coarser mesh size makes filter cleaning an easy task and they are cleanable and reusable.
