System Controls and Features
The Gas Engine Driven 30 CFM Air Compressor includes the following
controls and features (Figure 6):
•
Electric key start with recoil pull start backup.
•
Manual choke.
•
Compressor overtemperature switch (shuts down the engine).
•
Intelligent throttle which increases or decreases engine rpm based on air
demand (reduces fuel consumption when no air is needed).
•
Automatic system pressure unload with manual override (when the
system is “unloaded”, engine speed can be reduced, decreasing engine
noise, emissions and wear and tear, while increasing fuel efficiency).
•
Hour meter (runs any time the engine is running).
•
Automatic blowdown (depressurizes the system when it is shut down).
The electric fan on the WHASP Tank can turn on at any time.
This is normal operation.
