Product Description
KATMOTO COMP is a high-performance air compressor oil meeting DIN 51506 VDL, available in ISO VG 46 and 68, for rotary screw and reciprocating (piston) air compressors. Its oxidation- and thermally-stable formulation resists carbon and varnish formation at hot discharge temperatures, with strong anti-wear protection, rapid water separation and good air release for clean, reliable, long-life compressor operation.
Key Performance Features
| Oxidation & thermal stability
high RPVOT life resists oil oxidation at hot discharge temperatures. |
Low carbon/varnish formation
minimises deposits on valves, rings and discharge lines. |
| Anti-wear protection
protects compressor bearings, gears and cylinders. |
Rapid water separation
good demulsibility handles condensate in the air stream. |
| Good air release & low foam
minimises entrained air for efficient compression. |
Screw & piston suitability
suitable for rotary screw and reciprocating compressors. |
Applications & Performance Level
| Applications | Rotary screw and reciprocating (piston) air compressors requiring an ISO VG 46 or 68 DIN 51506 VDL compressor oil for hot-running, continuous-duty operation. |
| Specification | DIN 51506 VDL — air compressor oil standard for high discharge temperatures. ISO 6743-3 DAB / DAG — rotary and reciprocating compressor classifications. Low carbon residue — resists carbon and varnish at hot discharge. High RPVOT life — long oxidation life for extended drains. Screw & piston — suitable for both compressor types. |
| OEM Suitability | Rotary screw and reciprocating air compressors (Atlas Copco, Ingersoll Rand, Kaeser, etc.) specifying an ISO VG 46/68 VDL compressor oil. Follow the OEM manual for the correct grade and drain. |
| Important Notice | Use only where the equipment manufacturer specifies this grade and a matching performance level. ”Suitable for” does not mean official approval unless separately certified. Follow the OEM manual. |
