A coating material mist remover comprising: a first duct that discharges air containing coating material mist from an outflow port directed downward; a second duct having an inflow port directed in a horizontal direction; an intermediate filter that has a first duct connection portion on an upper face and a second duct connection portion on a side face, removes the coating material mist from the air, and is incinerable, the first duct connection portion being detachably connected to the outflow port of the first duct , and the second duct connection portion being detachably connected to the inflow port of the second duct ; a first connection mechanism that movably supports the first duct or the intermediate filter to a connection position where the first duct and the intermediate filter are connected to each other and to a separation position where the first duct and the intermediate filter are separated from each other, and holds the first duct and the intermediate filter at the connection and separation positions; and a second connection mechanism that movably supports the second duct or the intermediate filter to a connection position where the second duct and the intermediate filter are connected to each other and to a separation position where the second duct and the intermediate filter are separated from each other, and holds the second duct and the intermediate filter at the connection and separation positions, characterized in that the first connection mechanism comprises: an elevator guide that movably supports the first duct in a vertical direction to the connection position and the separation position; and an air actuator that alternatively urges the first duct to the connection position and the separation position by switch operation. a first duct that discharges air containing coating material mist from an outflow port directed downward; a second duct having an inflow port directed in a horizontal direction; an intermediate filter that has a first duct connection portion on an upper face and a second duct connection portion on a side face, removes the coating material mist from the air, and is incinerable, the first duct connection portion being detachably connected to the outflow port of the first duct , and the second duct connection portion being detachably connected to the inflow port of the second duct ; a first connection mechanism that movably supports the first duct or the intermediate filter to a connection position where the first duct and the intermediate filter are connected to each other and to a separation position where the first duct and the intermediate filter are separated from each other, and holds the first duct and the intermediate filter at the connection and separation positions; and a second connection mechanism that movably supports the second duct or the intermediate filter to a connection position where the second duct and the intermediate filter are connected to each other and to a separation position where the second duct and the intermediate filter are separated from each other, and holds the second duct and the intermediate filter at the connection and separation positions, characterized in that the first connection mechanism comprises: an elevator guide that movably supports the first duct in a vertical direction to the connection position and the separation position; and an air actuator that alternatively urges the first duct to the connection position and the separation position by switch operation. an elevator guide that movably supports the first duct in a vertical direction to the connection position and the separation position; and an air actuator that alternatively urges the first duct to the connection position and the separation position by switch operation. <EOS>
