Non-Woven Media
The most widely used media for pre-filters. Its non-woven structure gives different densities on the air-entry and air-exit faces — an ideal media with low pressure loss, high efficiency and good economy. It holds its shape through humidity changes and can be produced up to 2m wide in adjustable sizes.
