SPIRO H Oils have been formulated to provide optimum service life under arduous operating conditions which is demonstrated by the German DIN 51506 VDL specification that was developed to measure the lubricant’s resistance to the hazards of potential fires in air discharge systems. Spiro H Oils minimise the formation of carbon, varnish and sludge deposits thus reducing the potential fire risk. It is fully miscible with conventional mineral oil based compressor oils and seal materials. Not recommended for use in compressors used to fill air-breathing equipment
