What is a Foam Air Permeability Tester and Why It Matters
A Foam Air Permeability Tester is a precision instrument designed to measure the rate of air flow through foam materials. It uses the differential pressure method, applying a controlled pressure difference across the foam sample and quantifying how much air passes through it. This assessment helps determine the foam’s breathability and air flow resistance.
How It Works:
- The tester seals the foam sample in a chamber.
- A vacuum pump creates a pressure difference (usually 125 Pa).
- A highly sensitive Frazier differential pressure sensor measures air flow.
- The device calculates permeability in precise units such as L/s or scfm/ft².
Why It Matters:
Air permeability is a critical quality parameter in foam products. Measuring it ensures the foam meets standards for:
- Breathability: Essential for comfort in bedding, cushions, and apparel.
- Heat Dissipation: Good airflow prevents heat buildup, enhancing user comfort.
- Acoustic Performance: Controls sound absorption in acoustic foam.
- Durability & Performance: Helps predict foam longevity and behavior under use.
Accurate air permeability testing guarantees that foam materials deliver the performance and comfort expected in mattresses, automotive seats, furniture padding, and more.

Frequently Asked Questions (FAQ)
What is the difference between air permeability and air flow in foam testing?
Air permeability measures how easily air passes through foam, reflecting breathability. Air flow refers to the volume of air moving through the foam under pressure. Both are related but air permeability focuses on the material’s ability to let air through, while air flow is about the actual air volume moved during testing.
Can it test high-density memory foam?
Yes, the Foam Air Permeability Tester from Derui can test a wide range of foam types, including high-density memory foam, thanks to its sensitive Frazier differential pressure sensor and adjustable pressure settings.
Is the 125 Pa pressure fixed or adjustable?
The 125 Pa pressure is the standard testing pressure per ASTM D3574, but our tester allows adjustment depending on the specific test requirement or foam type, giving you more flexibility.
Do you provide calibration certificates?
Yes, each Foam Air Permeability Tester comes with a calibration certificate to ensure measurement accuracy and compliance with industry standards.
What is the lead time and payment terms?
Typical lead time is between 7 to 15 days after order confirmation. Payment terms are flexible, commonly including options like T/T, L/C, or online payment methods tailored to global customers.
