Hot Air Cotton is a nonwoven, nonwoven cotton fabric formed using ES fibers (two-component composite fibers of polyethylene and polypropylene) after passing through a single-layer hot air oven. The finished product is lighter in grams and can be made very thin. Hot air cotton does not require a needling machine, but a hot air oven. Appearance of hot air cotton is relatively smooth, through observation you can see the hot air cotton multi-layer fiber cotton bonding traces.
Our filter media rolls are offered in different sizes, thicknesses, and filtration grades to suit various air filtration systems. They can be tailored to fit specific needs and applications. The rolls and pads are specially designed to efficiently trap dust particles and have a large capacity to retain them, without releasing any fibers into the airflow.
