In which publication can general information about compressed air systems be found?

The publication that contains general information about compressed air systems is NSTM 551. This document provides comprehensive guidelines, system descriptions, and operational procedures specific to compressed air systems used in naval applications. Understanding the information in NSTM 551 is crucial for Machinist's Mates, as it covers safety practices, maintenance, and troubleshooting techniques necessary for effective operation and management of compressed air systems onboard.

NSTM 550 focuses on steam and other fluid systems, NSTM 553 covers fluid power systems and hydraulic pumps, while NSTM 557 deals with the maintenance of valves. Each of these publications has a distinct focus that does not specifically address compressed air systems in the way that NSTM 551 does. Therefore, NSTM 551 is the correct reference for acquiring general information about compressed air systems.
