Air compressors used in building sprinkler systems come with a variety of safety features to ensure reliable operation. These features include:

• Pressure relief valves to release excess system pressure;
• Pressure switches to monitor pressure and shut down the compressor if it exceeds or falls below a certain level; 
• Automatic drain valves to remove moisture from the system; 
• Overload protection to prevent damage due to excessive current; and 
• Thermal protection to prevent the compressor motor from overheating. 
  These features work together to ensure that the air compressor operates safely and efficiently, which is crucial for the safe and reliable operation of a building’s sprinkler system.
