DIN 51506 classification of piston air compressor lubricants
The most common are as follows:
- DIN 51506 VDL lubricants have additives that protect from corrosion and oxidation, and air compression temperatures up to 220°C; recommended for compressors with two stage air compression.
- DIN 51506 VCL lubricants have additives that protect from corrosion and oxidation, and air compression temperatures up to 160°C.
- DIN 51506 VBL lubricants have additives that protect from corrosion and oxidation, and air compression temperatures up to 140°C.
