Air Permeability
Tester:
The
“ASIAN” Air Permeability Tester for textiles consists of
an arrangement for holding the test specimens between two flat faces
so as to expose a known area to the flow of air through it, a vacuum
system to draw air through the exposed area of the test specimens.
There is an arrangement to measure the volume of air flowing through
the test specimen, and arrangement to measure the pressure drop
between the faces of the test specimen.
The test specimen
is hold between two round-shaped grips. The grips are lined with
rubber gasket to avoid the leakage of air through the edges. The two
grips can be held the test specimens with the help of a hand operated
screw mechanism.
The vacuum needed
to draw the air through the test specimens is created with the vacuum
pump supplied with the instrument. The vacuum pressure is measured by
the digital manometer (or manometer tube) in terms of mm of water
level & airflow is measured by the Rotameters attached with the
instrument. The equipment is metallic paint & bright chrome
plating finish for corrosion resistant finishing
