Filter cartridges for gas turbines and turbomachinery

Effective protection for maximum performance

Filter cartridges are crucial for protecting engines and turbomachinery from airborne contaminants to ensure their efficient operation and extend their service life. Our filtration solutions are designed to meet the stringent requirements of different environments, trapping particles before they can penetrate and damage sensitive machine components. We offer solutions for applications in coastal (salt), hot (heat), urban (dust) and tropical (humid) environments.

We offer a range of filter cartridges consisting of conical and cylindrical elements. These can be combined to create a customized solution to optimize airflow, increase particle separation efficiency and allow for specific installation configurations.

The choice of filter cartridge combination - whether conical & cylindrical or a simple cylindrical shape - depends on the specific requirements of the application, including the desired level of air cleanliness, space availability and maintenance. Each configuration offers unique benefits, from maximizing filter area and airflow distribution to simplifying installation and maintenance. Understanding these design differences is critical to selecting the appropriate filter cartridges.

Benefits

Filter cartridges for gas turbines and turbomachinery – Your customer benefits at a glance:
  • Reduced Energy and Operating Costs: Filter media with low pressure drop reduce energy consumption, extend the service life of the filters, and lower operating and maintenance costs.

  • Modernization of Existing Filter Systems: Retrofit existing gas turbine filter housings with high-performance cartridge filters to improve filter performance without major system modifications.

  • Reliable protection in harsh environments: Water- and salt-repellent filter media protect compressors and turbomachinery in coastal areas, humid environments, and demanding industrial settings.

  • Protect your investment in the turbine: High-performance filtration reduces the ingress of contaminants, extends the service life of the equipment, and lowers total operating costs.
