Product detail
Everything you need to specify
Compressed air contamination problems can be simply avoided by installing a Parker OFAS HL Oil Free Air System (including OIL-X filtration). The fully integrated heatless compressed air dryer and filtration packages are suitable for use with any compressor type and can be installed in the compressor room or at point of use.
Fitted with a third adsorbent column for oil vapour removal, Parker’s OFAS HL Clean Dry Air Systems have been third party validated by Lloyds register to provide ISO 8573-1 Class 0, with respect to total oil from both oil lubricated and oil free compressors, ensuring the highest quality air at the point of use for critical applications.
Clean, dry, oil free air improves production efficiency and reduces maintenance costs and downtime. Only OFAS HL Oil Free Air Systems can provide the highest levels of clean, dry, oil free compressed air with validated performance.

Why it matters
Clean, dry air pays back
The right filtration and drying shows measurable returns across the whole facility.
– Air loss
20-30%
Reduction in total air loss when leaks are properly sealed and repaired.
British Compressed Air Society
– ENERGY SAVINGS
~7%
Energy savings per bar of pressure drop recovered when filters are clean & dryers cleared
Hayley Dexis
– ELECTRICITY REDUCTION
10-15%
Electricity reduction as compressed air accounts for up to 30% of a facility’s total electricity bill
British Compressed Air Society
– INCREASED LIFESPAN
20-30%
Increase in the lifespan of pneumatic tools. Clean, dry air prevents this internal wear and tear.
