福州仓山区马尾壳牌齿轮油-空压机油经销处国外空气压缩机油的规格标准有德国DIN 51506和ISO/DP 6521.3，而最具有代表性的压缩机油的标准是德国工业标准DIN 51506。该标准是在20世纪70年代，因关心空气压缩机的安全性而提出来的。该标准中包含了VB（VBL）、VC（VCL）和VDL共3种级别的油品，适用于不同负荷空气压缩机的润滑。VB和VC为不含添加剂的纯矿物油，属于轻负荷型空气压缩机油；VBL和VCL则含有抗老化性能的添加剂，属于中等负荷型空气压缩机油:VDL属于高压、重负荷型空气压缩机油R1: "Anti-aging" must be translated as anti-aging. The specifications and standards for air compressor oils abroad include the German DIN 51506 and ISO/DP 6521.3, with the most representative standard being the German industrial standard DIN 51506. This standard was introduced in the 1970s due to concerns about the safety of air compressors. It includes three grades of oil: VB (VBL), VC (VCL), and VDL, suitable for lubricating air compressors under different loads. VB and VC are pure mineral oils without additives, classified as light-duty air compressor oils; VBL and VCL contain anti-aging additives and are medium-duty air compressor oils; VDL is designed for high-pressure and heavy-duty air compressor applications
