The PuroLube series of compressor fluids are formulated with the compressor’s design and operating environment in mind. Whether you have oil-flooded rotary screws or oil-free centrifugals, and regardless whether they operate in a “normal” cool, clean and dry environment or a hot, humid and acid-gas environment, we have the right oil for you. PuroLube compressor fluids and additive replenishing concentrates are formulated with a synergistic blend of premium base stocks and additive technologies designed to outperform the OEM fluids and deliver maximum protection, service life and economy for you and your compressors.
For “normal” applications
Fluid Metrics’ PuroLube improves upon the OEMs’ outdated formulations using advanced, cutting‐edge additive technologies that deliver superior stability and protection even under the harshest conditions. Beginning with the best fluid, and maintaining it with the best available technologies (COP & Additives), gives compressor users the absolute lowest fluid life‐cycle costs, and the ultimate in economy and compressor reliability.
Critical additives naturally deplete while in service which leads to reduced fluid service life. Specially formulated additives can be added to maintain fluid performance, increase the oil’s resistance to oxidation and acid gas contamination, neutralize harmful acids, improve corrosion protection, and extend oil change intervals.
PuroLube XD is a premium, full-synthetic Polyolester (POE) blend with an advanced additive system specially formulated to resist absorbing acids and is proven to deliver longer service life than other compressor fluids when operating in acid-gas environments. PuroLube XD provides outstanding thermal and oxidation stability and corrosion protection enabling it to exceed 10,000 hours service life in normal operating environments.
PuroLube TurboGold is an advanced blend of premium Polyoxyalkylene glycol (PAG) and Pentaerythritolester (POE) synthetic base stocks with advanced inhibitors, specially formulated for high speed centrifugal compressors. The result of more than 25 years experience formulating OEM compressor fluids, PuroLube delivers unsurpassed oxidative stability and deposit control ‐ especially critical in compressors with fixed geometry bearings, like IR’s CentacTM and others. PuroLube meets or exceeds OEM lubricant specifications, making it an excellent, cost effective pour‐in replacement for IR’s Techtrol Gold™, providing centrifugal compressor users exceptional performance and value!
