Air Permeability

In this experiment, Levron Aerogel Felt was placed in the center of the tube.
Water is filled into the tube and very low pressure air is blown through the bottom of the tube.
We observed that Levron Aerogel felt is water resistant and air permeable.

The air permeability of Levron Felt makes it a very suitable material for the production of breathable garments and household products.
