**What is the purpose of an air compressor in fire protection systems?**
An air compressor is used to maintain the necessary air pressure in dry-pipe sprinkler
systems.
**What should be done before operating an air compressor?**
Inspect the compressor, check oil levels, and ensure that the system is free from damage or
obstructions.
**How often should routine maintenance checks be performed on air compressors?**
Regular checks should be performed daily or before each operation.
**What type of lubricant is generally recommended for air compressors?**
Manufacturer-recommended oils, often synthetic compressor oils, are typically used.
**What should be done if you notice unusual noises or vibrations during the operation of an air
compressor?**
Stop the compressor immediately and conduct an inspection or notify maintenance
personnel.
**Why is it important to drain moisture from the air receiver tank regularly?**
1
, To prevent corrosion and ensure efficient compressor operation.
**What safety equipment should be used when operating an air compressor?**
Ear protection, eye protection, and proper clothing.
**What is the danger of over-pressurizing an air receiver tank?**
Over-pressurizing can lead to tank rupture or explosion.
**What is the role of the pressure relief valve in an air compressor system?**
It prevents over-pressurization by releasing excess pressure from the system.
**How do you check for air leaks in a compressor system?**
Use soapy water on joints and hoses to identify leaks by watching for bubbles.
**What should be done if an air compressor overheats?**
Shut down the compressor, allow it to cool, and check for clogged filters or obstructions in
airflow.
**Why is it important to maintain proper ventilation in the area where an air compressor is
operated?**
To prevent overheating and ensure the safe dissipation of exhaust and heat.
2
, **What is the function of an aftercooler in an air compressor system?**
It cools the compressed air to remove moisture and improve system efficiency.
**What is the maximum allowable pressure for most commercial air compressor systems used in
FDNY applications?**
It varies depending on the system, but typically around 125-150 PSI for standard air
compressors.
**What could cause an air compressor to trip off or stop unexpectedly?**
Overheating, electrical issues, or pressure switch problems.
**What is the recommended distance for placing an air compressor in relation to other
equipment or walls?**
Typically, at least 3 feet of clearance around the compressor is required for proper airflow
and maintenance.
**Why should an air compressor's intake area be kept clean?**
To prevent dirt and debris from entering the system, which could lead to operational issues or
damage.
**What are the common types of air compressors used in fire protection systems?**
Reciprocating (piston-type) and rotary screw compressors.
