PROBLEM TO BE SOLVED: To solve the problem that when air flowing through a central opening at one end side of a filtration section into its internal space is exhausted out of the filtration section, the air flowing through the central opening directly lashes the end plate of the other end side placed at the position facing the central opening and load is applied to the end plate. SOLUTION: In the internal space 2 of a filtration section 1, a shielding plate 5 is installed for preventing air, which flows through a central opening 3a of a first end plate 3 at one side end into the space 2, from directly lashing a second end plate 4 of the other end side. The shielding plate 5 is attached to a prop 6 installed uprightly from the first end plate 3 to the internal space 2 and is formed so as to be in a conical or hemispherical shape projecting toward the central opening 3a. The extension line of angle of the hem of the shielding plate 5 does not cross the second end plate 4. The shielding plate 5, the prop 6 and the first end plate 3 are integrally molded. |
