Description
Air permeability is defined as ‘the velocity of air flow passing horizontally through a test specimen, under specified conditions of test area, pressure drop and time’.
The instrument forces air through a specimen and adjust the flow of air gradually until a pressure drop is achieved.
The measurements will be taken multiple times dependent on the standard, and a mean air permeability would be expressed in millimetres per second or metres per second.

TestWise software
Our intuitive 7" touchscreen and TestWise allows the user to choose a pre-loaded standard or create their own. TestWise can detect the test area in use and warn the user if the wrong head is inserted.
Test reports are easy to view and analyse on screen and can be customised for export to Excel or PDF.
Large illuminated test bed
AirPro’s illuminated test bed can accommodate large samples and is suitable for testing a variety of different materials and finished garments.
Quick change test heads
A quick release mechanism means changing test heads is quick and easy, speeding up lab testing with less down time. Test heads can be changed without disconnecting the air supply or changing air pressure.
Quality and availability of parts
Focussing on the quality of the parts used to make AirPro, we've used medical grade valves (like those used in ventilators) to keep the airflow consistent, prolong its lifespan and maintain instrument performance.
When replacements are needed, the process is easy and reasonably priced.
