A good choice for pressurizing air behind a rack cabinet door is to mount a
“squirrel cage” blower inside the rack (Option 1 in Illustration 2-2). Mount
the blower at the bottom of the rack so it blows outside air into the space
between the door and in front of the amplifiers, pressurizing the “chimney”
behind the door. This blower should not blow air into or take air out of the
space behind the amplifiers. For racks without a door, evacuate the rack by
mountwer at the top of the rack to draw air out the back of the
cabinet (Option 2 in Illustration 2-2).
If the air supply is unusually dusty, it may be necessary to pre-filter it using
commercial furnace filters, etc., to prevent rapid loading of the unit’s own air
filter. When needed, the ammplifier's filter can be cleaned with mild dish
detergent and water
