High-Efficiency Barrier Filtration Protecting Gas Turbine Compressor Blades

Skytech Ultrafab Gas Turbine Air Intake Filter Cartridges are high-efficiency barrier filters engineered to remove airborne particulates, salt aerosols, and moisture from the intake air of gas turbines used in power plants, offshore platforms, and combined-cycle facilities. Manufactured from ePTFE membrane-laminated or high-loft glass fibre media on rigid structural supports, they achieve E10 to E12 absolute efficiency while maintaining extremely low pressure drop to maximise turbine output. Cartridge dimensions and bolt patterns conform to GE, Siemens, Solar, Rolls-Royce, and other major OEM housing specifications.

What Are Gas Turbine Air Intake Filter Cartridges?

Gas turbine air intake filter cartridges are the primary and final-stage barrier filtration elements installed in the inlet house of a gas turbine. The air intake system must deliver clean, dry air to the turbine compressor — any particulate, salt, or moisture contamination of compressor blades causes fouling, corrosion, and erosion that reduces turbine output, increases heat rate, and shortens compressor blade life. The cartridge filters are the last line of defence before air enters the compressor, so their efficiency, structural integrity, and low pressure drop are critical to turbine performance and availability.

Features and Benefits

• ePTFE Membrane Surface Filtration: ePTFE membrane on the upstream face provides absolute surface filtration — dust cake forms on the membrane surface and is released cleanly during pulse cleaning without media penetration or depth loading
• E10 to E12 Absolute Efficiency: Cartridges tested to EN 1822 achieving E10 (>85%), E11 (>95%), or E12 (>99.5%) fractional efficiency on MPPS — protecting compressor blades from sub-micron particle ingestion
• Ultra-Low Pressure Drop: Large pleated media area and low-resistance membrane construction minimise intake pressure drop — preserving turbine mass flow and power output compared to older glass-wool or felt stage filters
• Salt and Moisture Resistance: Hydrophobic ePTFE membrane repels moisture droplets and salt aerosols — critical for offshore, coastal, and high-humidity onshore gas turbine installations
• Pulse-Jet Cleanable: Cartridges designed for online pulse-jet cleaning by the turbine inlet house automated pulse system — restoring low differential pressure without cartridge removal
• OEM Housing Compatibility: Cartridge outer dimensions, bolt-hole pattern, and gasket sealing face manufactured to match GE, Siemens, Solar, MHI, and major OEM turbine inlet housing tube-sheet specifications

Technical Specifications

Applications

• Gas Turbine Power Plants: Inlet air filtration on open-cycle and combined-cycle gas turbines at inland, coastal, and desert power generation stations requiring high efficiency and pulse-cleanable cartridges
• Offshore Oil and Gas Platforms: Salt-laden and moisture-rich offshore air environments — ePTFE membrane hydrophobic cartridges are mandatory for compressor protection on offshore gas turbine generator sets
• LNG and Petrochemical Plants: Gas turbine driven compressors in LNG liquefaction trains and petrochemical plants where turbine availability directly impacts plant production output
• Combined Heat and Power (CHP): Industrial gas turbines in CHP and cogeneration facilities where inlet filter pressure drop directly impacts turbine electrical output and heat rate
• Aero-Derivative Turbines: High-efficiency cartridges for aero-derivative gas turbine inlet systems where the compact inlet housing design requires low-profile, high-performance cartridge elements
