The air permeability tester is an equipment usually used for quick and accurate determination of air permeability of almost all types of flat materials and foam cubes. In the textile industry, they are widely used to test the air permeability of airbag fabric and significantly open non-woven and forming fabrics. The machine can also be used to test air permeability of dense papers.

Salient Features

• The instrument is easy and simple to use.
• It has a small size and is mobile and can easily be used in the production area.
• It can work both automatically and digitally.
• Provided with a powerful vacuum pump that fetches air through an interchangeable test head having a circular opening.
• For the purpose of measurement, the test head is installed on the instrument.
• The test specimen is placed on the test head opening by compressing the clamping arm, which in turn stars the vacuum pump automatically.
• The vacuum pump is closed down by compressing the clamping arm second time leading to the release of test specimen.
• Flow of air through the test sample is calculated via a variable fissure.
• Air permeability of the specimen under test is obtained from the pressure drop in the fissure and is displayed digitally.

Applications

There are many different applications of air permeability tester. Some of its common application area are:

• Textile Industry
• Paper & Pulp Industry
• Petroleum Industry
• Research Laboratories
• Soil Analysis
• Gas Plants
