Air Permeability Tester
Engineered for Excellence: Textest Air Permeability Testing Systems for Reliable, Consistent Material Performance
Solutions for all your testing needs
Air permeability testing measures how easily air can pass through a fabric or material. It’s like checking how “breathable” a material is, which is important for things like sportswear, outdoor clothing, and even technical fabrics used in furniture or filters. This test helps manufacturers make sure their products have the right level of air flow-whether that means keeping you cool or providing proper ventilation for technical textiles. For test setup and result interpretation, read our air permeability testing guide.

Frequently asked questions
Help with model selection, test requirements and buying in India.
Who manufactures these instruments, and who supplies them in India?
TEXTEST Instruments, Switzerland, manufactures these instruments. Flexitest is the authorised sole exclusive distributor for TEXTEST instruments in India.
Which model should I consider for laboratory testing?
Start with the FX 3300-IV LabAir for laboratory testing of fabrics, foams and spacer fabrics. For a compact benchtop instrument, mobile checks or a backup tester, consider the FX 3340 MinAir. The right choice depends on your material, test method and measurement range.
What is the difference between MinAir and FlexAir?
The FX 3340 MinAir is suited to benchtop and mobile fabric testing, with battery operation available as an option. The FX 3345 FlexAir is designed for mobile testing of contaminated flat materials, including used filters, and tensioned fabric webs. FlexAir includes an integrated rechargeable battery.
How do I choose equipment for ASTM D737 or ISO 9237?
Start with the test method and edition specified by your buyer or laboratory. Share the required test area, pressure difference, material and expected airflow range with Flexitest so the model, test head and configuration can be matched to your application.
Can I measure air permeability on a moving production web?
Yes. The FX 3370 SpotAir supports manual spot checks and continuous profiles when mounted to the production line. The FX 3500 CombiScan uses a traversing test head to monitor profiles across the moving web. Choose according to the measurement coverage and line integration you need.
What information should I share for a quotation?
Send your material type, required test method, test area and pressure, expected airflow range, and whether you need laboratory or production-line testing. For online measurement, include web width and line speed. Mention any reporting or data-export requirements so Flexitest can recommend a suitable configuration.
