  • Synthetic ester base high-performance lubricant
  • Will not varnish or form carbon deposits
  • Less wear and lower energy consumption
  • Built-in detergency action

DGX Premium D-100 is a high-performance compressor lubricant formulated from synthetic ester base fluids with an ISO Viscosity Grade 100, a flash-point of 260°C, and built-in detergency action. It has a USDA Food Grade classification H-2 rating and is packaged in a black HDPE easy-pour jug containing { 1 US Gallon | 3.785 Litres } of lubricant that is factory sealed with re-closeable safety lock cap.

The polar nature of ester molecules results in a stronger film that better adheres to metal surfaces, which translates into higher lubricity with less wear and lower energy consumption in lubricant applications. DGX Premium D-100 provides outstanding thermal and oxidation stability plus it will not varnish or form carbon deposits. DGX Premium D-100 is designed for use in multi-stage reciprocating high-pressure compressors commonly used in the SCUBA diving industry. DGX Premium D-100 is intended for use in breathing air applications and suitable for Nitrox (nitrogen, oxygen) and Trimix (nitrogen, oxygen, helium) gas mixtures up to a maximum of 40% oxygen.

Compressor Lubricants and Diver Safety

The USDA Food Grade nature of some synthetic lubricant formulations is often mentioned in the marketing of those lubricants. How important is that to health and safety in breathing air applications? The answer is debatable, but the edibility of lubricants is probably not meaningful for evaluating their safety in breathing gas compressors used for diving applications. Both polyalphaolefin-based and ester-based lubricants used in breathing air applications are considered low-toxicity.

It is true that food grade lubricants cannot contain known carcinogens, mutagens, teratogens, mineral acids or contain heavy metal additives such as antimony, arsenic, cadmium, lead, mercury or selenium. However, lubricants intended for breathing air applications are not formulated with those substances in any case. Regardless, high-pressure compressor lubricants can contain performance enhancing additives for which there is "no data available" about their safety for use in breathing air applications.

The risk of decomposition from high temperature operation or inadequate maintenance of high pressure compressors used in breathing gas applications is far more pernicious. All lubricants begin to decompose over time during usage and this occurs more rapidly in higher temperature conditions. Exceeding usage limits by just 'topping up' the lubricant level instead of complete replacement at recommended intervals will also result in decomposition. The decomposition of lubricant is associated with formation of highly toxic chemical byproducts that can overwhelm and pass through filtration into the SCUBA tank. Ester based lubricants, with their excellent performance in higher temperature applications and superior oxidative stability, may offer significant safety advantage in this regard especially if compressing Nitrox.

To put the lubricant safety issue in perspective for divers: the reality is that mineral oils, polyalphaolefins, and esters have all been used for years to lubricate high-pressure compressors with breathing air applications. For a properly maintained compressor with filtration to deliver the very pure CGA Grade "E" quality verification level breathing air recommended for SCUBA, the amount of lubricant contamination is so low that their food safety is irrelevant.
