Introduction to metal breathable joints

Metal breathable joints are key components used in equipment or systems to allow air or gas to flow freely while preventing moisture, dust or other particles from entering. It is usually used in situations where it is necessary to maintain internal pressure balance, remove gas or prevent external environmental influences, such as electronic equipment, communication equipment, sensors, instruments, etc.

Main functions

Ventilation function:

Allow air or gas to flow freely between the inside and outside of the equipment to help balance the pressure inside the equipment.

Protection function:

Through the filtering structure, it prevents impurities such as moisture, dust, oil mist, etc. from entering the equipment and protects internal components from the external environment.

Explosion-proof function (some specially designed breathable joints):

Used in explosion-proof equipment to ensure safe release of internal gas in overpressure conditions to avoid equipment damage or explosion.

Structural features

Metal breathable joints are usually made of metal materials such as stainless steel or aluminum alloy, with good corrosion resistance and mechanical strength. The interior usually contains a microporous filter element or a multi-layer structure, and fine channels are formed through precision machining to effectively filter particulate matter while ensuring smooth gas flow.
