AIR DAMPER
NOTE
Opening th
e entrance door also partially
closes the fresh air damper.
Return air is drawn from inside the vehicle
through the register duct located on L.H. side of
vehicle (Figure 2).
A double blower fan unit, which is activated by
the evaporator motor, draws mixed air through
an air filter, cooling and heating coils, then
forces this air in the ventilation ducts (upper
section) along the walls, and finally exhausts it
at the bottom of the windows.
The coaches are equipped with an overhead
compartment ventilation system equipped with
adjustable registers in the passenger’s overhead
console to control air flow. Return air is drawn
just below the middle side windows through an air
filter into the overhead compartment fan;
discharge air is fed to the rotating registers
through the ventilation duct (Figure 45).
The lavatory ventilator found on the coach acts
as the main exhaust for the whole vehicle,
eliminates odors, and finally heats or cools the
lavatory with the vehicle’s ambient air.
