: • 20,000 at 0.1 microns – 0.5 microns
• 400 at 0.5 microns – 1.0 microns
• 10 at 1.0 microns – 5.0 microns
Maximum water vapor pressure dewpoint: 3°C (37°F)**
Maximum oil concentration: 0.1 mg/m

(for aerosol, liquid, and vapor)
* Important: Any air compressors that supply air to the cutting system must remove oil prior to air delivery.
** Speak to your air compressor manufacturer if you operate the cutting system in temperatures colder than 3°C (37°F)
or if you are unsure that the air compressor can comply with the ISO standard for air quality.
NOTICE
DIRTY, OILY AIR CAN CAUSE DAMAGE TO THE AIR FILTER BOWL
Synthetic lubricants containing esters that are used in some air compressors can cause damage to the
polycarbonates in the air filter bowl. Add additional gas filtration if necessary.
