Claims

[Scope of Claim for Utility Model Registration] 1. A casing provided with an intake port at the front for sucking mist-containing air, an intake passage continuous behind the intake port, and an exhaust port at the rear for discharging the air after removing the mist. The casing is provided with an intake fan and a main filter for removing mist from the inhaled mist-containing air inside the intake passage, and the intake passage includes:
In a mist removal device formed with a large-diameter rectification chamber that rapidly expands the mist-containing air that has been drawn in,
A filter support network is installed in the rectification chamber at a distance from the outlet of the rectification chamber, and a rectification chamber filter is detachably provided at the front of the filter support network at a distance from the entrance of the rectification chamber. Features a mist removal device. 2. The mist removal device according to claim 1, wherein the rectifying chamber filter is attached to a filter shape retaining net and held in a constant shape. 3. Claim 1 or 2, characterized in that the peripheral wall of the rectification chamber is provided with a filter attachment/detachment hole through which the rectification chamber filter can be attached/detached from the outside of the rectification chamber, and a lid for opening/closing this filter attachment/detachment hole. The mist removal device described.
