“Clean compressed air means cleaner production, longer machine life, and better profits.”

In every industry — from pharma packaging to PET bottle blowing and automobile painting — compressed air quality plays a vital role. Even tiny traces of oil, water, or dust can spoil your product, damage machines, and increase maintenance costs.

 Why Air Purity Matters

Compressed air carries three hidden enemies — oil mist, moisture, and dirt particles.
Controlling these ensures:

  • Better product quality

  • Lower downtime

  • Longer compressor and tool life

Clean air also helps meet strict industry standards like those in pharma, food, and packaging sectors.

 Filter Types and Their Uses

Screw compressors use multiple filters to remove contaminants:

  • Particulate Filters: Remove dust, rust, and solid dirt.

  • Coalescing Filters: Eliminate oil aerosols and water mist.

  • Activated Carbon Filters: Remove oil vapors and bad odors for odorless, clean air.

  • Air Dryers: Reduce moisture and prevent rust or corrosion in pipelines.

Together, these ensure pure, dry, and safe compressed air for sensitive operations.

 Preventing Oil, Moisture & Dirt Contamination

  • Use oil-free compressors for pharma or food plants.

  • Drain air tanks and filters regularly.

  • Clean or replace filters as per schedule.

  • Keep intake air clean by avoiding dusty areas.

  • Install automatic drain valves to remove condensate efficiently.

Clean air means reliable production.
