air permeability apparatus: Air Permeability test machine for Leathers

Labthink provides Air Permeability Test Machine for textiles and non-wovens. 

Labthink Air Permeability test Machine has two test methods:

• Method A

• Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference.

• Method B

• Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time.
