Levron Air Permeability
In this experiment Levron Aerogel Felt is placed in the middle of the tube. Water is filled into the tube and very low pressured air is blown from the bottom of the tube. We could observe that Levron Aerogel felt is water resist and air permeable.
The air permeability rate of Levron Felt ensures that it is a very suitable material for manufacturing breathing clothes and houses.
