Title:
流量センサーの出力ノイズを小さくする方法
Document Type and Number:
Japanese Patent JP6737543
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the output size of a flow sensor arranged downstream of an air cleaner element by enhancing the reliability of the filtration performance of the air cleaner element using pleated nonwoven fabric filter medium.SOLUTION: A nonwoven fabric filter medium (1) is a nonwoven fabric filter medium having a laminated structure of nonwoven fabric layers (11, 12) with different porosities. The coefficient of static friction of an exposed face of the nonwoven fabric filter layer (12) on the smaller side in porosity out of the exposed nonwoven fabric filter layers is 0.3 or less. The nonwoven fabric filter layer (12) on the smaller side in porosity out of the exposed nonwoven fabric filter layers is preferably treated with a fluorine-based treatment agent or a silicone-based treatment agent.SELECTED DRAWING: Figure 1
