Higher Stage of Compressor = ?
Low RPM
What pressure is taken first in an Engine
Lower
What does a High Pressure Control Valve do
Used to determine the source of engine compressor stage
What does a Ground Pneumatic Connection do
Acts as a Pneumatic Hose Adaptor with intergrated Check Valve
What does a LP Check Valve do
Prevents reverse flow to the engine low stage compressor
What does a Fan Air Valve do
Regulates Pneumatic Supply Temp
What does a Pressure Regulating Valve do
Shuts off or Regulates the Pneumatic supply pressure
What does a Over Pressure Valve do
Closes incase of malfunction of the Pressure Regulating Valve
What does a Heat Exchanger do
Used to cool pneumatic air with air fan
What does a Isolation Valve do
Split or Connect the different Pneumatic Systems
What does a APU Bleed Valve do
Shuts off or Allow APU Bleed air supply
