Compressed air filtration is essential for maintaining clean air quality and protecting downstream equipment. Domnick Hunter filter cartridges are widely used in compressed air systems to remove contaminants such as oil aerosols, water, solid particles, oil vapours, and odors.
When the original filter cartridge reaches the end of its service life, choosing a suitable replacement helps maintain filtration efficiency, airflow performance, and system reliability.
Filson replacement Domnick Hunter filter cartridges are designed for various Domnick Hunter housings, with accurate dimensions, multiple models, and consistent filtration performance. With 18 years of filtration manufacturing experience, Filson has supplied replacement filter solutions to customers in more than 30 countries.
Why Replace Domnick Hunter Filter Cartridges?
During continuous operation, filter elements gradually collect contaminants from compressed air. As the filter becomes saturated, it may lead to higher pressure drop, reduced airflow, and increased energy consumption.
Regular replacement of Domnick Hunter filter cartridges helps:
- Maintain stable compressed air quality
- Reduce pressure loss
- Protect downstream equipment
- Повышение эффективности фильтрации
- Extend system reliability
Choosing the correct replacement filter element is essential for achieving consistent filtration performance.

- Precision manufacturing
Replacement is recommended when oil vapour or odor breakthrough occurs.
GL / GL Plus Domnick Hunter Compressed Air Filter Element
GL and GL Plus Domnick Hunter filter elements are designed for compressed air purification applications requiring multiple filtration functions.
They are suitable for:
- High-efficiency coalescing filtration
- Dry particulate removal
- Oil vapour removal
Filson replacement GL / GL Plus filter elements are manufactured with suitable filter media and accurate dimensions to ensure compatibility with original Domnick Hunter housings.
How to Choose the Right Domnick Hunter Replacement Filter Cartridge?
Selecting the correct replacement filter cartridge depends on the filtration requirements and operating conditions.
| Selection Factor | Considerations |
|---|---|
| Filtration Grade | Grade AA: Fine coalescing filtration for oil aerosols and liquid contaminants Grade AO: Particle and general oil aerosol filtration Adsorber: Oil vapour and odor removal GL / GL Plus: Combined compressed air filtration functions |
| Housing Compatibility | The replacement filter element should match the original Domnick Hunter housing model, dimensions, and installation requirements. |
| Operating Conditions | Important factors include: • Скорость потока • Operating pressure • Temperature • Contaminant type |
Choosing the correct filter cartridge helps maintain filtration performance and avoid unnecessary maintenance costs.
