Why Oil-Free Is Non-Negotiable for PSA

Oil contamination is the #1 cause of premature molecular sieve failure. Even trace oil vapor from lubricated compressors will coat CMS/Zeolite pores, irreversibly reducing adsorption capacity.

Class 0 (ISO 8573-1) compressors deliver zero oil carryover — ensuring maximum sieve lifespan (5-8 years) and consistent PSA performance. The small premium for oil-free technology pays back 3-5x through extended sieve life alone.
