<p>Filtration media includes a polymeric based impregnation material that is impregnated within a fabric material such as felt, non-woven fabric or woven fabric material. The impregnation material may be coated on a first surface of the fabric material and subsequently heated air may be passed through the coating and fabric material. The heated air may be passed through the fabric material via a pressure differential that is defined in a volume that fully encloses the fabric material for a predetermined period of time to ensure that the hot air pushes the coating through a substantial thickness of the fabric material to be impregnated within the fabric material throughout the substantial thickness of the fabric material. A heat cure step may subsequently be applied to ensure that the coating is diffused in to the fabric material and cured.</p> |
