RENOLIN ZAF D

Zinc and Ash-Free, Detergent Hydraulic Oils

Zinc and Ash-Free, Detergent Hydraulic Oils

Zinc- and ash-free hydraulic oils have steadily gained popularity over the last few years. In many cases the use of a zinc-free hydraulic oil is a must, especially in machine tools where hydraulic oils can contaminate other functional fluids.
RENOLIN ZAF D hydraulic oils are zinc- and ash-free hydraulic oils with good detergent properties. The detergent agents in these oils reduce the formation of residues and ageing by-products.
They are HM hydraulic oils in line with ISO 6743-4 but with additional detergent and dispersant characteristics.

The most important features of RENOLIN ZAF D hydraulic oils are:

  • Good oxidation stability and good resistance to ageing
  • Powerful EP properties and very good wear protection
  • Excellent corrosion protection
  • Rapid air release and low foaming
  • Good sludge transportation and cleaning properties
  • Good compatibility with sealing materials
Application:

RENOLIN ZAF D products are high-grade HM hydraulic oils in line with ISO 6743-4 which can be used in all hydraulic systems but also as CKC lubricating oils in line with ISO 6743-6. RENOLIN ZAF D products contain additives which avoid the formation of residues and guarantee the functional reliability of machinery.
