Add more gas filtration
Add additional, external filtration if necessary to keep a clean, dry gas line.
- Prevent oil, water, dirt, and other contaminants from causing damage to internal components.
- Get optimal cut quality and consumable life.
Dirty, oily air is the root cause of many common problems that occur in Powermax® systems. In some conditions it can void the warranty on the plasma power supply and on the torch. Refer to the gas quality recommendations in the ratings tables that start on Hypertherm plasma power supply ratings.
The plasma power supply contains a built-in air filter. Regularly do a check of the filter element inside the air filter bowl and replace it as necessary. Refer to Maintenance for the air filter bowl and filter element.
- You work in an environment that is very warm and humid.
- Your work site conditions introduce oil, vapors, or other contaminants into the gas line.
A 3-stage coalescing filtration system is recommended. A 3-stage filtering system works as follows to clean contaminants from the gas supply.
| 1 | Water and particle filter |
|---|---|
| 2 | Oil filter |
| 3 | Oil vapor filter |
The filtering system must be installed between the gas supply and the plasma power supply.
- Kit 128647: The Eliminizer moisture removal air filter removes water and dirt from the gas supply. For more information, refer to the Optional Air Filter Kit and Element Replacement Procedure Field Service Bulletin (804180).
- Kit 428719: The oil removal air filter removes oil, oil aerosols, and dirt from the gas supply. For more information, refer to the Optional Oil Removal Air Filter Kit and Element Replacement Field Service Bulletin (809610).
If you use both external filters, install them in the order shown to prevent damage to the gas line and equipment.
