Abstract
A filter holder assembly includes at least one frame having a peripheral wall and an inwardly directed peripheral edge substantially perpendicular to said peripheral wall and adapted to support a filter. At least one cam lock lever is secured to the peripheral wall at a first predetermined distance from the inwardly directed peripheral edge for compressing the filter in the frame and against said inwardly directed peripheral edge. 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.

A filter holder assembly comprising at least one frame having a peripheral wall and an inwardly directed peripheral edge substantially perpendicular to said peripheral wall and adapted to support a filter;
- at least one cam-lock lever secured to said peripheral wall at a first distance from said inwardly directed peripheral edge for compressing the filter in said frame and against said inwardly directed peripheral edge, said cam-lock lever having a handle portion at one end thereof and a cam head provided with a cam foot at an opposite end thereof, wherein said cam lock lever is rotatable about a pivot pin to cause said cam foot to move between an open position and a clamping position wherein, in said clamping position, said cam foot exerts a compressive force on said filter, and wherein said cam foot is axially aligned with said handle portion and a longitudinal axis of said cam lock lever passing through said handle portion and said pivot pin.
A filter holder assembly comprising at least one frame having a peripheral wall and an inwardly directed peripheral edge perpendicular to said peripheral wall and adapted to support a filter;
- at least one cam-lock lever secured to said peripheral wall at a first distance from said inwardly directed peripheral edge for compressing the filter in said frame and against said inwardly directed peripheral edge, said cam-lock lever having a handle portion at one end thereof and a cam head provided with a cam foot at an opposite end thereof, wherein said cam lock lever is rotatable to cause said cam foot to move between an open position and a clamping position wherein, in said clamping position, said cam foot exerts a compressive force on said filter;
- and
- wherein said cam foot is laterally offset from said cam head and has at least one upturned edge.
