Ultrafiltration

What is Ultrafiltration?

Ultrafiltration is a rigidly controlled “cleaning” or filtering process that removes microscopic particulates from synthetic oil and grease.  Nye can ultrafilter grease in our certified clean room environments to eliminate possible contaminants that can cause precision bearings and instruments to fail.

Nye’s Ultrafiltration Process

Nye offers ultrafiltration services for not only our own greases, but also for those produced by other manufacturers. Many lubricant companies only filter their grease after it has been produced and before it goes into an unwashed container that can contaminate the lubricant. At Nye, we ensure ultraclean grease by following a strict manufacturing process from start to finish.

This manufacturing process includes the removal of volatile contaminants from our base oils and additives - drop by drop - using molecular stills. These stills use elevated temperatures under vacuum conditions to extract volatile molecules from the fluid. This remaining stripped fluid is separated from the volatile contaminants and becomes the new base oil for ultraclean lubricants.  This process is then repeated for our additives. Our ultrafiltration process then deposits the lubricant directly into the end of use containers that have been thoroughly cleaned beforehand.

Certified Clean Rooms

All of this happens in our ISO class 8 and class 7 certified clean rooms. Airborne particles and specified limits are controlled in the clean room environments. Nye follows strict protocol and methods to ensure temperature, humidity, air flow and air filtration is maintained to the highest standard to prevent cross-contamination of any kind. Our technicians are thoroughly trained and wear special garments including hair nets, booties, gloves, and gowns.
