MOBILAIR M500-2 - 100% OIL FREE AIR up to 45.8 m³/min (1617 cfm)

The HPC KAESER MOBILAIR M500-2 combines all the advantages of a two-stage, dry-running rotary screw compressor with those of mobile units: Maximum compressed air quantity and quality with maximum flexibility.

Portable oil-free compressed air is an indispensable partner for many specialist applications in the UK including the oil & gas, food & beverages, industry & manufacturing, drilling & mining, pharmaceutical and power generation industries. It provides the energy to power a wide variety of specialist equipment and tools and is also invaluable for a diverse range of applications plus cleaning, maintenance and repair tasks.

For industrial equipment with high compressed air requirements, the M500-2 ensures continuity of compressed air supply even during maintenance or renovation work. Easy to integrate into existing stations, another area of application is refineries (e.g. for pipeline flushing).
