What is a high temperature air permeability tester used for?

A high temperature air permeability tester is used to measure the air permeability of materials under elevated temperature conditions. It is commonly applied in testing filter materials, industrial fabrics, nonwovens, and high-temperature resistant textiles to evaluate performance in real working environments.

What materials can be tested with this equipment?

This tester is suitable for a wide range of materials, including: High-temperature filter media Industrial woven and nonwoven fabrics Composite materials Automotive heat-resistant textiles Protective clothing materials

Why is high-temperature testing important?

Standard air permeability tests at room temperature may not reflect real operating conditions. Many materials expand, soften, or change structure at high temperatures. High-temperature testing ensures: Accurate performance evaluation Reliable filtration efficiency data Better prediction of service life

What temperature range does the tester support?

Depending on the model, high-temperature air permeability testers typically support a range from ambient temperature up to 200°C, 300°C, or even higher for specialized applications.

What is the maximum temperature the tester can reach?

The High Temperature Air Permeability Tester is capable of reaching a maximum temperature of 1650℃, making it suitable for high-temperature material testing applications.

How does the tester ensure accurate temperature control?

The tester utilizes an intelligent temperature control module that measures and controls the temperature with an accuracy of ±1℃. This ensures that the testing conditions are consistent and reliable.

What is the furnace temperature uniformity like?

The furnace temperature uniformity is maintained within ±5℃, ensuring that all samples within the furnace are subjected to the same testing conditions, which is crucial for accurate permeability testing.
