Title:
FILTER FOR AN AIR-CONDITIONING OR HEATING SYSTEM FOR MOTOR VEHICLE
Document Type and Number:
Japanese Patent JPH04284802
Kind Code:
A
Abstract:

PURPOSE: To retain activated carbon particles on the filter, even when the particles come off the filter, by covering the filter arranged in numerous layers and having pores which are coated with activated carbon particles with air- permeable flat fabric material.

CONSTITUTION: A filter 10 is composed of four layers 11 consisting of a plate of polyurethane foam and an air out-let side is covered by reinforcing lattice 13. A polyurethane foam is provided with open pores and the areas of the pores are coated with an absorption agent of activated carbon particles. The filter 10 body is wrapped with flat fabric material 12 with each fiber yarn of the fabric maintaining a distance between each other which is shorter than the outer diameter of the activated carbon particle, thereby it is possible, even when an activated carbon particle comes off from a pore of the filter material, to prevent such a particle from being released from the filter 10.
