Wholesale Industrial Dust Extraction Gas Turbine Air Filter Paper

This filter paper is engineered for high‑efficiency particulate removal in gas turbine inlet air systems where dust accumulation can degrade compressor performance and increase fuel consumption. The material combines a controlled pore structure with a thermally stable substrate to meet the stringent demands of continuous turbine operation.

Product Overview

The paper is manufactured from a blend of synthetic fibers and cellulose, calibrated to achieve a target basis weight that balances mechanical strength with low airflow resistance. Surface treatments can be applied to enhance moisture resistance without significantly affecting permeability.

Technical Characteristics

• Basis weight: 80–150 g/m² (adjustable per customer spec)

• Air permeability: 120–300 L/min·m² at 125 Pa pressure drop

• Initial filtration efficiency (0.3 µm DOP): 85–99.5%

• Maximum continuous operating temperature: 180 °C

• Tensile strength (MD/CD): ≥15/≥12 kN/m

Applications in Gas Turbine Dust Extraction

Gas turbines ingest ambient air that contains silica, pollen, and industrial dust. Even sub‑micron particles can foul compressor blades, raising the pressure ratio required for a given thrust and increasing specific fuel consumption. A filter paper with high efficiency in the 0.3–1.0 µm range reduces fouling rates while maintaining a low pressure drop (<150 pa="" at="" rated="" flow="">

The substrate’s thermal stability ensures that the filter does not deform or release fibers during transient temperature spikes up to 180 °C, which can occur during rapid load changes.

Customization Options

Roll width can be supplied from 200 mm up to 2000 mm, with standard lengths of 50 m or 100 m per roll. Adjustments to basis weight, fiber blend, and surface treatment allow the filter to be tuned for specific dust loading conditions and installation constraints.

• Basis weight: 80–150 g/m²

• Air permeability: 100–350 L/min·m² @125 Pa

• Surface treatments: hydrophobic coating, antistatic layer, flame‑retardant finish

• Roll dimensions: width 200–2000 mm, length 30–150 m

Quality Control Approach

Each production lot undergoes basis weight verification using a calibrated gravimetric method, air permeability measurement via a standardized test head, and filtration efficiency testing with a DOP aerosol generator. Visual inspection identifies defects such as tears, foreign inclusions, or coating irregularities before the material is slit and wound.

Statistical process control charts monitor key parameters, and a batch is released only when all measured values fall within the agreed tolerance bands.
