Overview

AirPro is a consistent and accurate Air Permeability tester, used to test the resistance of the flow of air through woven, knitted and non-woven textile materials. It is supplied with TestWise software, making it intuitive and easy to use.

AirPro can be used on a variety of applications, including performance apparel, medical textiles, PPE, infant products such as bedding, non wovens, geotextiles and more.

Features

Quick change test heads

A quick release mechanism means changing between test heads is quick and easy, speeding up laboratory testing with less down time between tests.

Changing the test head can be done without disconnecting the air supply or changing air pressure.

TestWise software

Our intuitive 7" touchscreen and TestWise allows the user to choose a pre-loaded standard or create their own. TestWise detects the test area in use and warns 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.

Suitable for testing a variety of different materials and finished garments.

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.

About the test method

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.
