Glass fiber filter media rolls for air intake filter production

Gas Turbine Filter Media Manufacturer for Air Intake Filtration

We manufacture glass fiber filter media for gas turbine and compressor air intake filters. Our CFA SS, CFE SS and CFH SS series offer ten grades with defined efficiency, pressure drop and water resistance, supported by consistent mechanical specifications for filter production.

10 SS grades MD tensile strength 1.50 kN/m Water resistance ≥500 to ≥800 mmH₂O by grade

Media Grades for Staged Intake Filtration

Efficiency is specified at 0.3 μm and 5.3 cm/s using TSI 8130A. Pressure drop is specified at 5.3 cm/s. Stage suitability depends on the complete filter and intake system.

CFA SS Series filter media roll

CFA SS Series

Models: CFA0263SS, CFA0463SS, CFA1663SS and CFA1863SS.

Specified efficiency thresholds range from ≥20% to ≥80%, with pressure-drop limits from ≤15 to ≤75 Pa. Water resistance is ≥500 or ≥600 mmH₂O by model. Evaluate CFA SS grades for lower-resistance filtration stages and upstream load management within the approved intake design.

Balance Capture, Resistance and Moisture Exposure

Select against the required particle-control performance and total intake-pressure allowance. Filter area, pleat design, weather protection and contamination loading determine how the media behaves in the installed system.

Review My Intake Conditions
Selection priority Grades to examine Defined trade-off
Lower initial media resistance CFA0263SS to CFA1863SS Increasing capture thresholds across CFA are paired with pressure-drop limits of 15, 35, 50 and 75 Pa.
Finer capture with water-resistance options CFE3263SS to CFE5863SS CFE3263SS specifies ≥600 mmH₂O; the remaining CFE grades specify ≥800 mmH₂O, with higher resistance limits.
High particle-capture targets CFH7263SS and CFH7463SS The two grades share physical properties and ≥800 mmH₂O water resistance, with different efficiency and resistance limits.

Strength and Media Structure for Intake Filter Production

Mechanical Properties Across All Ten Grades

Every SS model lists MD tensile strength of 1.50 kN/m and CD tensile strength of 0.60 kN/m. Gurley stiffness is specified at ≥1000 mg for CFA and the first three CFE grades, and ≥950 mg for CFE5863SS and CFH. These values provide a defined basis for converting and pleat-support evaluation.

Tensile MD 1.50 kN/m
Tensile CD 0.60 kN/m

Gradient Depth Construction

We use a gradient media structure to distribute particle capture through the material. Web formation and bonding are developed around the filtration requirement, with performance evaluated together with the intended filter construction.

Model-Specific Water Resistance

The range offers ≥500, ≥600 and ≥800 mmH₂O water-resistance specifications. This makes moisture exposure a measurable material-selection criterion alongside capture performance and pressure drop.

Controlled Thin Media Formats

Specified thicknesses range from 0.33±0.03 to 0.37±0.03 mm, with basis weights of 72±3 or 75±3 g/m². These dimensions support comparison for compact pleated designs without assuming a finished-filter flow rating.

Turbine Intake

Conceptual intake stages. The final arrangement is determined by the system design.

Operating environment Main selection concern Starting points in our range
Desert and dry, dusty sites Contamination loading, dust distribution and total pressure drop Evaluate CFA SS for upstream duty and CFE/CFH SS for downstream particle control according to the turbine requirement.
Coastal and humid power stations Moisture, salt aerosol and wet-condition pressure behavior Compare CFE3263SS at ≥600 mmH₂O with CFE3663SS and higher-capture SS grades at ≥800 mmH₂O.
Offshore platforms Salt exposure, access constraints and final-stage integrity CFH7263SS and CFH7463SS are high-capture candidates; validate wet and salt performance in the assembled filter.
Urban industrial sites Fine dust, soot and mixed particulate contamination CFE SS and CFH SS provide finer-capture options after upstream loading control.
Rainy inland sites Moisture combined with deposited dust Review the CFE water-resistance options together with drainage, weather protection and loaded-filter behavior.

A media water-resistance value does not measure salt-removal efficiency or prove weatherproof performance of an assembled filter. Evaluate the selected construction under the site’s moisture and aerosol conditions.

Address the Causes of Intake Filter Mismatch

1 Selection
2 Filter Validation
3 Operation Monitoring

Rising pressure drop

Dust loading and moisture can change filter behavior during operation. Our grade table establishes the initial material comparison; loaded-filter evaluation helps determine the final choice and maintenance approach.

Converting damage

Handling tension, pleat geometry and support design can affect media integrity. Use the shared SS tensile values and model-specific stiffness with manufacturing trials before releasing the filter design.

A specification based only on efficiency

A high percentage omits important operating information. Our model comparison brings efficiency, resistance, water resistance and mechanical properties into the same selection process.

In-House Media Manufacturing and Filtration R&D

We manufacture filter media and support application-specific development from laboratory trials through pilot evaluation and batch production. Raw-material controls include checks on glass fibers, binders and additives.

Our filtration laboratory supports material-property evaluation, microstructure analysis and filter-performance development. The engineering discussion connects the SS grade, converting process and intended intake-filter construction.

Samples and small trial orders are available for customer evaluation. We can agree the test conditions and acceptance criteria for the media before the project moves to repeat production.

Gas Turbine Filter Media Selection Questions

Should every site use the highest-efficiency grade?
No single grade is appropriate for every intake design. Site contamination, required particle removal, filter area, pressure allowance and the turbine manufacturer’s requirements determine the selection. Our CFA, CFE and CFH SS grades provide different material starting points for that assessment.
Can I use the listed media pressure drop as the intake-system pressure drop?
No. The table describes media tested at 5.3 cm/s. Filter geometry, area, seals, other filtration stages and the intake structure affect the complete system. Use the table for material comparison and assess the finished filter at its design airflow.
Does ≥800 mmH₂O establish salt protection or rain resistance?
It is a water-resistance property of the medium, not a salt-retention result or a complete weather rating. Coastal projects also need appropriate moisture management and assembled-filter evaluation under wet and salt-aerosol conditions.
Are these media approved for pulse-jet cleaning?
Pulse-cleaning suitability is not specified for the SS grades listed here. Reverse-pulse duty requires evaluation of the media, support construction, dust release and repeated cleaning cycles. Discuss the cleaning regime before selecting a grade.
What testing should be considered for a gas turbine intake filter?
Start with media efficiency, pressure drop and mechanical properties, then evaluate the assembled filter under the project’s operating and contamination conditions. ISO 29461-1 addresses static intake filter elements for rotary machinery; its scope is different from a media measurement on a TSI 8130A. ISO 29461-1 test scope.
Does the listed loss on ignition prove flame retardancy?
No. The 8% or 10% loss-on-ignition value is a material parameter. A fire classification requires the applicable fire-test method and results for the relevant material or assembly.
Can you provide samples or develop a custom grade?
Yes. We support samples and small trial orders for evaluation, together with application-specific media development. Share the target test conditions, environmental exposure, filter construction and order requirements so we can define the trial scope.
