Sterile Compressed Air Filter

Pharmaceutical and analytical applications demand more than standard compressed air filtration. This Omega Air filter is specifically configured for sterile, bacteria-free and particle-free compressed air — removing microorganisms, oil aerosols, oil vapour and sub-micron particles to produce air that meets ISO 8573-1 Class 1 and GMP manufacturing requirements. Essential for tablet coating, blister packaging, fermentation, analytical instruments and any compressed air that contacts product or product contact surfaces.

Filtration Train

Recommended 3-Stage Filter Train

Pharmaceutical and food-grade compressed air requires a multi-stage approach. Each stage removes a specific contaminant, and together they produce air that meets ISO 8573-1 Class 1 for both particles and oil — the standard demanded by regulatory bodies for product-contact air.

Class 1
Pharma Grade
Grade P — Particulate Pre-Filter
The first stage removes particles down to 3 µm including rust, pipe scale, compressor wear metal and bulk dust. Protecting the downstream sterile element from premature loading significantly extends service life and reduces operating cost.
Grade S — Sterile / Bacterial Filter
The critical barrier stage. The S-grade element removes oil aerosols to 0.01 µm and captures bacteria, spores and microorganisms at 99.9999% efficiency. Residual oil content is reduced to ≤0.01 mg/m³, meeting the ISO 8573-1 Class 1 oil class requirement.
Grade ACS — Activated Carbon
The final polishing stage removes residual oil vapour, taste and odour from the air stream. Essential for food contact, pharmaceutical cleanrooms and analytical instrument carrier gas to prevent vapour contamination of product or measurement.
Where It's Used

Typical Applications

💊
Tablet Coating & Packaging

Compressed air contacting tablet coating pans, blister packing machines and solid dosage product lines must be bacteria-free and oil-free per GMP and Schedule M requirements.

🧫
Biopharmaceutical Fermentation

Sterile air for bioreactors, fermenters and cell culture vessels where any microbial contamination in the air supply could destroy an entire production batch.

🧪
Analytical Instruments

Zero air and carrier air for GC, HPLC, ICP-MS and mass spectrometry instruments. Oil vapour contamination at ppb levels can invalidate chromatographic results.

🌾
Food & Beverage Contact

Direct-contact packaging air, pneumatic conveying of food powders, filling lines and carbonation systems requiring FSSAI-compliant oil-free, bacteria-free air.

🏥
Hospital Cleanrooms

Sterile manufacturing cleanrooms, aseptic fill suites and hospital pharmacy compounding areas requiring EU GMP Annex 1 compliant sterile compressed air.

💉
Injectable Filling Lines

Vial and ampoule filling, lyophilisation loading and stopper bowl aeration where compressed air contacts sterile product or primary packaging materials.

Air Quality Standard

ISO 8573-1 Purity Classes

The P + S + ACS filtration train produces compressed air that meets ISO 8573-1 Class 1 — the highest purity class — for both oil content and particulate. This is the class required by most pharmaceutical and food-grade applications.

ISO Class Max Particle Count (≥0.1 µm/m³) Max Oil Content (mg/m³) Typical Application
Class 1 ✓ Achieved ≤20,000 ≤0.01 Pharma, food contact, sterile
Class 2 ≤400,000 ≤0.1 Electronics, painting, general
Class 3 ≤90,000,000 ≤1.0 General industrial use
Class 4 Not specified ≤5.0 Heavy industrial
