What is an Air Trap?

When asked “What is an air trap?”, it can be explained as:
An air trap is a device that allows air to be expelled from air and liquid systems. It is also known as a steam trap. Air traps work by using a chamber or other mechanism to trap or separate air from the flow of water or other liquids in the system.

Operating Principle of an Air Trap (Steam Trap):

Air traps operate based on different principles depending on the flow of air and liquid. The most common operating principle is the float (buoyant) type. In float-type air traps, a component called a float opens and closes according to the direction of air and liquid flow, allowing air to be discharged from the system.

Types of Air Traps (Steam Traps):

Air traps are classified into four main types based on their operating principles: float-type, thermostatic, check valve, and automatic air vent.

• Float-Type Air Traps: This is the most commonly used type of air trap. Float-type air traps open and close according to the direction of air and liquid flow, allowing air to be discharged from the system.
• Thermostatic Air Traps: These air traps are used in hot water systems. Thermostatic air traps open and close based on the water temperature, allowing air to be discharged from the system.
• Check Valve Air Traps: These air traps are used in pressurized air systems. Check valve air traps discharge air from the system through a check valve mechanism.
• Automatic Air Vents: These air traps are used in hot water and pressurized air systems. Automatic air vents open and close based on water or air pressure, allowing air to be discharged from the system.

Applications of Air Traps (Steam Traps):

Air traps are used to remove air from air and liquid systems. Their applications include the following:

• Heating and cooling systems
• Compressed air systems
• Irrigation Systems
• Industrial Plants
• Chemical Plants
• Food facilities
