OIL FREE SCREW COMPRESSORS
BUILT FOR CRITICAL APPLICATIONS
Pure, reliable air with ELGi’s Class 0 certified OF Series
At Pneumatic Engineering, we supply ELGi’s OF Series oil-free air compressors—combining Class 0 certified air purity with energy
efficiency and reduced maintenance costs. Featuring ELGi’s patented ŋ-V rotor design and corrosion-resistant components, these compressors are engineered for long-term performance in demanding environments.
Whether you’re operating in food manufacturing, pharmaceuticals, healthcare, or electronics, our oil-free systems deliver guaranteed contamination-free air backed by local expertise.
The ELGi Advantage
Historically, oil-free systems meant high costs and low efficiency. ELGi has changed the game with the OF Series:
- ŋ-V Rotor Design reduces pressure losses and improves stage efficiency
- Corrosion-resistant coatings withstand up to 250°C and extend lifespan
- Improved energy efficiency and reduced maintenance costs
- Locally supported by WA’s largest independent compressed air service team
Why Oil-Free?
In industries where even microscopic traces of oil can cause product spoilage, equipment failure, or regulatory issues, oil-free compressors are essential. These systems remove the risk of oil carryover entirely, making them ideal for:
- Food & beverage processing
- Pharmaceutical manufacturing
- Medical & dental facilities
- Electronics & cleanroom environments
- Chemical & petrochemical plants
- Water & wastewater treatment
- Cryogenics
Understanding the Difference
Unlike oil-lubricated compressors, oil-free models don’t use oil in the compression chamber—eliminating the need for downstream filtration and the risk of contamination. This makes them the preferred choice in clean-critical environments.
Class 0 Certified for Total Peace of Mind
Only ISO 8573-1 Class 0 certification guarantees zero oil carryover. Lower classifications allow trace levels of oil that can still compromise your process. ELGi’s OF Series meets Class 0 standards, giving you complete confidence in your air quality.
