Product Features
Double Layer Gradient Gas Turbine Filter Media combines a unique two-layer structure with high-strength composite construction, delivering efficient fine particle capture with extended service intervals for turbine intake systems.
Double Layer Gradient Structure: The double layer gradient gas turbine media features a unique two-layer design where the upstream coarse layer captures larger dust particles and the downstream fine layer ensures high efficiency. This structure maximizes dust holding capacity and extends service life.
High Dust Holding Capacity: The high dust holding turbine intake filter utilizes the gradient structure to distribute particle loading across both layers, preventing premature clogging and maintaining low pressure drop throughout the service life.
High Mechanical Strength: The high strength synthetic glass filter sheet incorporates a high content of synthetic fibers, providing enhanced mechanical resistance and improved pleating performance for reliable filter element fabrication.
Superior Liquid Repellency: Advanced surface treatment provides top-level water and oil repellency, preventing liquid ingress that could cause turbine corrosion and fouling.
PFAS-Free Option: Water repellent solutions are available without PFAS, meeting environmental and regulatory requirements.
Broad Efficiency Range: Available from ePM1 70% to H13 efficiency levels, accommodating various turbine protection requirements from fine to sub-micron particle capture.
Product Applications
Double Layer Gradient Gas Turbine Filter Media is deployed as final-stage static filtration in gas turbine intake systems, protecting turbines from fine particulate contamination in variable weather conditions.
Power Generation Turbines: Installed in combined-cycle and peaking power plants, the media captures fine atmospheric particles that could cause turbine blade erosion and fouling.
Industrial Gas Turbine Packages: Provides high-efficiency protection for compressor station and industrial facility turbines operating in environments with fine pollution.
Coastal and Offshore Installations: The liquid repellent properties make it suitable for marine environments where salt-laden moisture poses corrosion risks.
Multi-Stage Filtration Systems: As final filtration stage, the media removes fine particles that passed through pre-filters, ensuring turbine intake air quality meets OEM specifications.
