The RAPTAIR MF unloads the air pressure in the system, which
minimizes fuel burn, equipment wear, enclosure temperature and
noise, when compressed air is not being used.
If the plumbing downstream from the RAPTAIR MF is tight (has no
leaks), a 5 gallon air receiver is adequate. If you use an auxiliary air
tank with this system, the line to the auxiliary tank must be installed
as high as possible (not in the bottom of the tank) to prevent water
from clogging the line. Failure to observe these requirements will
result in damage to the system.
A one-way check valve is built into the RAPTAIR MF
tank. Do not install an additional check valve as this
may cause undesirable operation.
2.2 Ventilation Requirements
During operation, the RAPTAIR MF can develop
considerable heat,
Proper ventilation is vital for proper operation and to
avoid damage to components.
Ensure there is a minimum of 6" (150mm) clearance between cooler
grills on diesel drive units and any other components mounted on the
vehicle. Also ensure there is a good supply of cool air to the service
panel side of the unit, and good exhaust from the radiator side.
Direct the diesel exhaust to vent to atmosphere and in a safe
location.
The engine radiator fan pushes hot air from the unit. Cold air is
drawn in through the service panel.
2.2.1 Top Mounting
This is the preferred mounting location. Placing the unit on top of the
service body (Figure 2.2 -Mounting locations) provides the best
access to ambient air and provides the best cooling. Maintain a
minimum of 6” between the service panel and radiator to solid
objects. Maintain a minimum of 2” to the other sides.
