How a Pneumatic RF Shielding Chamber (Shell Style) Works？

 1. Air Supply Provision First

Input air pressure parameters:

A. Input air pressure: 0.5~0.6 MPa

B. Outer diameter of air connector: 6mm quick-connect fitting (outer diameter)

C. Connecting air tube: 6mm in diameter

Note: The shielding chamber cannot work normally under either high or low air pressure. It can only operate properly when the compressed air pressure meets the operational requirements. Meanwhile, for the air supply system, the compressed air entering the air circuit system of the shielding chamber must be dried and filtered through an air filter.

2. Power Supply

Power is supplied via AC (Alternating Current).

3. Opening and Closing Operation

Press the "Open" key to open the shielding chamber.

Press the "Close" key (press simultaneously if required by the specific model) to close the chamber.

Additionally, according to the internal testing requirements of the shielding chamber, the downward pressing action of the internal fixture can be achieved (via corresponding control).

4. Alternative Automatic Operation

The automatic opening and closing of the shielding chamber can also be realized through commands, which is more concise and convenient.

In conclusion, the shell-style shielding chamber is favored by customers and widely used in manufacturing and testing processes due to its advantages such as easy operation, cost-effectiveness, convenient maintenance, durability, and excellent isolation performance.

Key Terminology Explanation (for clarity in technical scenarios) -

Pneumatic RF Shielding Chamber: A device that uses pneumatic (air-driven) mechanisms to achieve electromagnetic shielding, preventing external radio frequency (RF) interference from affecting internal tests and blocking internal RF signals from leaking outward.

Quick-connect fitting: A standardized connector for air tubes, enabling fast assembly and disassembly without tools, commonly used in pneumatic systems.

Isolation performance: In this context, it refers to the chamber`s ability to isolate external electromagnetic interference, a core technical indicator of RF shielding equipment.
