Figure 8-47
If the degree of protection of the Cabinet Modules is to be increased, the additional hoods
and filter media are delivered separately.
The hoods are flush with the cabinets at the side and front and have a recess at the rear so
that air can escape even if the cabinet is wall mounted. Air escapes from the front and back.
The hoods are easily fitted and filter media easily changed from outside the cabinet. Air
escapes from the front and back. Compliance with the increased degree of protection
requires intact filter media, which must be replaced on a regular basis according to the
prevailing environmental conditions.
