Why Oil-Free Matters

Oil contamination = downtime, spoilage & costly losses.

Food & Beverage → safe packaging, processing, nitrogen generation

Pharma → blister packaging & conveying

Semiconductors → strict cleanroom air standards

Automotive → flawless paint, no fisheyes

Plastics → injection & stretch blow molding (up to 81k bottles/hr)

System Design Notes

Even with an oil-free compressor, dryers and filters are always required to remove moisture, particles, and ambient hydrocarbons. Together, this ensures compliance with ISO 8573-1 Class 0/1 air quality - the global benchmark for industries where product contamination is not an option.
