Abstract:
1. A filter element having pulverized adsorbent powder adhered to an adhesive-coated base fabric surface, which satisfies the relationship that 0<A <1.1 mB+C and m=0.28−0.0005 D 50 , with the proviso that 0<C<15, where D 50 (μm) is the 50% particle diameter of the pulverized adsorbent powder, B (g/m 2 ) is the amount of the pulverized adsorbent powder adhered to the base fabric, A (Pa) is the pressure drop of the filter element as measured at room temperature under an air flow rate of 1 m/ sec, and C (Pa) is the pressure drop of the base fabric coated with the adhesive and dried.
