Air Compressor Maintenance


A reliable source of clean, dry air under the proper pressure is necessary for Dry and Preaction Fire Protection Systems. Proper air pressure requirements will be determined at the time of the system design. If the air pressure is too low, the dry valve may accidentally trip when exposed to a surge in water pressure. If the air pressure is too high, the time between the opening of a sprinkler and the flow of water to the sprinkler may be too long. 

A fire protection air compressor is one option available to provide this necessary air supply for Dry and Preaction Fire Sprinkler  Systems. Proper steps should be taken to ensure an air compressor is working properly and will maintain the air needed for your system. Below are some recommended steps to follow for your air compressor maintenance routine.


  • Check gauge reading for consistency (compared to previous inspections)
  • Drain moisture from air compressor tank
  • Check for unusual noises or leaks
  • Check oil level


  • Inspect electrical connections and arrange for any corrective action to be taken safely and properly
  • Inspect belt for wear and tear
  • Confirm bolts are tight
  • Change air filter


  • Change oil (confirm type with User Manual)

Having a solid air compressor maintenance plan in place can maximize longevity of the compressor and maintain the air supply needed for your sprinkler systems. In addition, regularly scheduled inspections of your fire sprinkler systems are critical to the reliability of the systems.
