The S-500 Crystal Clean™ media are made of cellulose/polypropylene non woven fibers which

have been specifically engineered to provide a high degree of particle removal with extended life for coolants and emulsions. The combination of cellulose and polypropylene allows small particles to be captured deep within the S-510 & S-520 media without causing the media to blind prematurely.
