Mobil SHC Rarus 46 (55 Gal. Drum)
Engineered for severe-duty service, Mobil SHC Rarus 46 is a supreme performance air compressor lubricant recommended for rotary screw and vane air compressors. Mobil SHC Rarus 46 has the potential to deliver up to three times the oil drain intervals compared to other leading synthetic compressor lubricants. With a viscosity index of 122, Mobil SHC Rarus 46 is ISO viscosity grade 46, with a -44 degrees F (-42 C) pour point and a flash point of 387 degrees F (197 C). This product ensures excellent control of sludge and varnish build-up in crankcases and discharge lines, reducing blockage of coalescers and coolers. Mobil SHC Rarus 46 is durable and multi-metal compatible, offering exceptional resistance to rust, wear and corrosion. The outstanding water separability of Mobil SHC Rarus 46 also reduces carryover to downstream equipment.
Mobil SHC Rarus 46 is a replacement for the discontinued Mobil Rarus SHC 1025.
- Outstanding thermal / oxidation stability help to provide up to three times oil drain interval versus a leading synthetic compressor oil and reduce maintenance downtime
- Excellent varnish and sludge control helps to deliver cleanliness and extended compressor oil life
- High performance synthetic base stocks with high viscosity index enables wide temperature range capability and effective lubrication at high temperatures
- High load carrying capability protects equipment and extends life, helps minimize unexpected downtime and extend service periods
- Exceptional resistance to rusting and corrosion, very good antiwear, demulsibility, foam control and air release and multi-metal compatibility
- Excellent water separability helps reduce carryover to downstream equipment, reduce sludge formation in crankcases and discharge lines, helps reduce blockage of coalescers, coolers and less potential for emulsion formation
- Mobil SHC Rarus Series are primarily for rotary screw and vane air compressor, very effective in screw type compressors with oil injection cooling; compressors with a history of excess oil degradation, poor valve performance or deposit formation
- Compressors operating under severe conditions, particularly effective for continuous high temperature operation with discharge temperatures up to 200ºC
- Compressor systems with critical gears and bearings
- Not for air compressors used in breathing air applications
- Compatible with all metals used in compressor construction and with conventional mineral oil-based air compressor oils but mixture with other oils may detract from the total performance capability
