The LAD Filter is mounted together with the LAD fan in the light engine compartment. This assembly is
secured to the light engine handle. The LAD filter is responsible for filtering the already filtered air from the
light engine compartment, which is then directed to each DMD via clear tubing. The LAD filter rarely requires
replacement, but should be inspected regularly.
