  • Publication number: 20110122378
    Abstract: A filter apparatus which holds a chemical filter includes a frame which holds the chemical filter and which has a guide groove provided on a side surface of the frame; and a casing which accommodates the frame. The guide groove has a first groove which is communicated with a back surface of the frame, and a second groove which is communicated with the first groove and which extends from a front surface of the frame toward an upper end thereof. The casing has a shaft member which is engageable with the first groove to support the frame and which is engageable with the second groove to release the frame from being supported. It is possible to install the filter efficiently so that the filter can be positioned with ease, and to unload the filter efficiently.
