Replace the air filter bowl and filter element
It is extremely important to maintain a clean, dry gas line in order to:
Prevent oil, water, dirt, and other contaminants from damaging internal components.
Achieve optimal cut quality and consumable life.
Check the filter element inside the air filter bowl regularly,
especially in environments that are very dusty or very warm
and humid. Replace the filter element when it is dirty or
starts to deteriorate. See page 161 for part numbers.
Keep the filter bowl and its O-ring free from oil, chemicals,
dirt, and other contaminants. These contaminants can
prevent a good seal, causing gas to leak and additional
contaminants to enter the gas line. Over time, these
contaminants can damage internal components.
If you are using an external filtration system –
such as the Eliminizer filter kit (128647) that
Hypertherm provides – also check that filter
regularly for required maintenance or cleaning.
It is normal to see a small amount of water in the bottom of the filter bowl. The filter bowl
automatically purges excess moisture when enough water accumulates to engage the float
mechanism inside the bowl.
1. Set the power switch on the power supply to
OFF (O). Disconnect the power cord from the
power source.
2. Disconnect the gas supply from the back of the
power supply.
3. Remove the air filter bowl by unscrewing the metal
guard until it detaches from the air filter
assembly inside the power supply.
Use an adjustable wrench if needed to
loosen the filter bowl. However, be careful
not to damage the polycarbonate bowl
inside the metal guard.
CAUTION
Synthetic lubricants containing esters that are used in some air compressors will damage
polycarbonates used in the air filter bowl.
