IPAC Releases New Compressor Fluids Handbook

By Jeff Crow, on July 1, 2015

There are many different types of compressors on the market today, each with its own unique demands.  Reciprocating compressors, for instance, have been used predominately over the years; however, many new types are now in service, such as flooded rotary screw compressors, rotary vane compressors, as well as centrifugal and dry screw compressors.

Compressors often operate under severe conditions and require high-performance fluids. Many times a synthetic fluid is required. Diesters are often the fluid of choice for rotary screw compressors, one of the more common compressor types today. However, PAO, PAG and polyol esters are also used extensively.

There are several fluid formulations, each highlighted in the handbook, that dominate the lubrication of these compressors. Many compressor specifications such as DIN 51506 are focused on the rust and oxidation performance, and not on anti-wear performance. Other specifications, such as SAE MS1003 do require some anti-wear properties for the medium and heavy duty service, especially with rotary vane and screw compressors.  On the low end are mineral oil formulations with R&O type additives.  For heavier duty and with rotary vane or screw compressors, some level of anti-wear performance is recommended, as well as synthetic basestocks in some instances.

IPAC’s new handbook provides critical details and guidelines for formulating various levels of air compressor fluids.  Contact your IPAC representative for more details and to gain access to this important sourcebook.
