<P>PROBLEM TO BE SOLVED: To provide a filter holding assembly that can replace a filter in a short time. <P>SOLUTION: A filter holder assembly includes at least one frame having peripheral walls 12, 14, 16, 18 and inwardly directed peripheral edges 20, 22, 24, 26 substantially perpendicular to the peripheral walls and adapted to support a filter. At least one cam lock lever is secured to the peripheral walls at a first predetermined distance from the inwardly directed peripheral edges for compressing the filter in the frame and against the inwardly directed peripheral edges. The cam lock lever has a handle portion at one end thereof and a cam head provided with a cam foot at an opposite end thereof. The cam lock lever is rotatable to cause the cam foot to move between an open position and clamping position where the cam foot exerts a compressive force on the filter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
