Examine the air filter bowl and O-ring

Notice

DIRTY, OILY AIR CAN CAUSE DAMAGE TO THE AIR FILTER BOWL

Some air compressors use synthetic lubricants that contain esters. Esters can cause damage to the polycarbonates in the air filter bowl.

Add more gas filtration if necessary.

Make sure that no oil, chemicals, dirt, or other contamination is on the filter bowl or the O-ring.
- Contamination can prevent a good seal and cause gas leaks.
- Contamination can also go through the gas line to the plasma power supply or torch and gradually cause damage to internal components.
Make sure that the O-ring does not have cracks or other damage.
Clean the air filter bowl by removing oil, dirt, or other contaminants.

Yellow material on the filter bowl can be a sign that oil is getting into the gas supply line.
Replace the air filter bowl and O-ring as necessary.
If you use an external filtration system, such as the Eliminizer filter kit, also do a regular check of that filter for necessary maintenance or cleaning.
