FUCHS RENOLIN UNISYN OL 150 Is a fully synthetic hydraulic oil.


Synthetic EP air compressor oils based on PAO, for turbo, screw, vane and piston compressors; High-performance synthetic, PAO-based hydraulic fluids.


Compressed air has become a major form of energy and the reliable generation of compressed air is vital. Operators require compressors to function perfectly over and beyond entire service intervals.

The FUCHS RENOLIN UNISYN OL series was developed to meet the increased requirements of compressor manufacturers on the service life of compressor oils.
Due to the function of compressors, intensive swirling of the cooling oil and air occurs. At high compression temperatures, the oils are subjected to a strong oxidative attack that accelerates ageing. The selection of special synthetic base oils and additive systems makes long, interruption-free operation possible. To ensure optimum performance of the oil separator, the air release properties and low foaming are characteristic for screw and turbo compressor oils. RENOLIN UNISYN OL 32, 46 and 68 offer long service life, and they fulfill the requirements mentioned above as well as the requirements according to DIN 51506 VDL.

The most important functions of lubricating and cooling oils in screw compressors are:

* Cooling the compressed air
* Bearing lubrication
* Sealing the chambers
* Corrosion protection
* Preventing the formation of deposits.

RENOLIN UNIYSYN OL 32, 46 and 68 have especially been developed for the use in oil injected screw compressors and in turbo compressors.

RENOLIN UNISYN OL 100 and 150 are recommended in particular for long-term use in piston and rotary compressors that must meet the strict requirements for low residue formation according to DIN 51506 VDL.

RENOLIN UNISYN OL fluids can also be used as hydraulic fluids according to DIN 51524.


• Excellent viscosity-temperature behaviour (high natural viscosity index), shear-stable
• Excellent oxidation stability
• Low evaporation losses
• Excellent wear protection (EP/AW!)
• Excellent FE8 performance
• Good demulsifying properties
• Excellent corrosion protection
• Good compatibility with elastomers
• Low foaming / good air release
• Suitable for high-temperature applications
• Synthetic hydraulic fluids, excellent deep temperature flowability
• Exceed DIN 51506 – VDL


RENOLIN UNISYN OL products are recommended for use in flooded or oil injection screw-type air compressors and turbo compressors (ISO VG 32, 46, 68) and for piston and rotary vane compressors (ISO VG 100, 150).

RENOLIN UNISYN OL products should always be used if mineral oil-based products are found to display insufficient thermal stability (resistance to ageing) or poor viscosity-temperature behaviour.

Compared to mineral oil-based oils, RENOLIN UNISYN OL products foam less, offer better demulsification and have superior air release

The use of RENOLIN UNISYN OL products is especially recommended in unfavourable conditions and at high temperatures in which other oils fail because they allow coke to form, thus leading to unacceptably short oil life. These oils are also recommended for compressors which are subject to extreme loads.

Compared to mineral oil products, the life of RENOLIN UNISYN OL products is considerably longer, operational reliability is much improved and breakdowns are effectively reduced (service intervals can be extended).

RENOLIN UNISYN OL products can also be used as hydraulic fluids, especially with good lowtemperature behaviour.
