Carefully place the filter element to avoid damaging the filter membrane and deforming the end cap. First, remove the old filter element and set it aside, then clean the interior of the dust collector. Remove the new filter element from the packaging and inspect the surface for stains, material cracks, and end cap deformation. Gradually insert the filter element into the cage bracket, aligning the core hole with the screw. Flatten the filter element and tighten the butterfly nut. The installation method for filter elements of different specifications and models should be confirmed with our technical engineer.
