Why Are Air Compressors Important in a Building’s Dry Sprinkler System?
A Fire protection air compressor assists in protecting your building, its occupants and your bottom line.
The air compressor is used to pressurize the sprinkler system piping with compressed air. When a fire occurs, and a head trips, this loss of pressure opens the valve, activating waterflow.
South-Tek Systems offers many air compressor solutions to meet your sprinkler specifications:
- Pressure requirements
- Air quality needs
- Gallons of pipe capacity
- Air flow output demands
Air Compressor FAQs
What features are provided on air compressors?
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.
What is the average lifespan of an air compressor?
A well-maintained air compressor can last up to 15 years.
Why do I need an air compressor for my nitrogen generator system?
Air compressors serve many purposes in a nitrogen generator system, including initial fill, generation of nitrogen and supervising system pressure.
Do I need a specific air compressor for my nitrogen generator system?
A nitrogen generator’s production of nitrogen gas is advantageous for various reasons. Without nitrogen gas, regular air takes it’s place. Air contains oxygen and water vapor which can wreak havoc on military equipment that needs to be reliable when it matters most.
Additionally, nitrogen generators are convenient, without a nitrogen generator to provide a continuous supply of nitrogen gas, cylinder delivery and management must be relied upon. Disadvantages of nitrogen generators include the up-front cost, which is more significant than ordering individual cylinders of nitrogen in the short-term, but pays off in the long run.
