Compressor lubricants

[gkrasley]

Hello Diving community,

I happened upon some old threads regarding the use of Chemlube 800 in Bauer high pressure compressors. There was some information posted that was incorrect. Chemlube 800 is indeed specifically formulated for high pressure applications such as Bauer and has been successfully lubricating these units for many years. Please feel free to visit our website for additional information. Premium synthetic oils, industrial lubricants, compressor oils, and gear oils | Ultrachem Inc..

Thank You

Been using Ultrachem products for years. I never did so much damage to my Mako 5406 compressors as I did with Chemlube 800. It glazed every cylinder wall in all 4 stages of 2 compressors. The original OEM oil was Chemlube 751, which I used faithfully until I switched to Chemlube 800 for the higher flashpoint, then I got to completely rebuild both of my 5406's after about 500 hours. I am now happily using Chemlube 501B and both of my compressors operate exactly as Compair designed them.

When I asked my sales rep at Ultrachem why I was having glazing problems on my cylinder walls, he told me that the 800 was designed as a gearbox oil for commercial food mixers/preparers. Why would he say that if it were designed for air compressors?

Don't get me wrong, I am a firm believer in Ultrachem's products. I will use 501/501B/751 as long as I own high pressure compressors. I will never again use 800 in a high pressure compressor. I am happy it works in Bauers, maybe Mako compressors run hotter? Maybe it isn't right for the higher oxygen contents of Nitrox? I don't know the answer, but after rebuilding my compressors, breaking them in with mineral oil, flushing twice with 501B, they work like a champ and have now for a couple of years.

Thanks for the information. I've got a gallon of 800 I was going to put in a K14 I just had rebuilt. I guess I'll order some 751.
