2940 Air Adjust System Information
2940 Air Adjust requires a stable air supply source that can provide a
minimum of 75psi of clean, dry air. The 'clean, dry air' is a key
component of the air supply, moisture within the air supply can
shorten the life cycle of the system. Yetter compressors should build
to 145psi on the tank gauge before shutting off. When pressure in
the tank drops below 120psi, the compressor will engage to build
back up to 145psi. Other pneumatic systems, for example pneumatic
down force or air clutches, can be plumbed using the Yetter
compressor as its air source. Be sure to regulate the air entering any
other systems to OEM specifications.
