In medical facilities, universities, and research institutes, various equipment and devices are installed, and the electromagnetic waves and noise emitted from these devices can interfere with the reading of weak electrical signals. Shielded rooms are installed in many facilities to improve such environments. Our company enhances the noise shielding from electrical circuits that were previously unclear and offers them as medical shielded rooms. Leveraging over 30 years of experience, we respond to various requests in different settings.

The "SAN-type Shield Room" is a panel-style shield room that uses expanded mesh for the ceiling and the upper half of the walls. Due to the breathable and transparent nature of the expanded mesh, ventilation systems, air conditioning systems, lighting systems, and fire prevention systems may not be necessary depending on the application, resulting in excellent cost performance. The panels have sufficient strength, allowing for self-supporting installation without needing support from the building, and they can be installed directly on existing floors. It has been used as a shield room for regular inspections of marine statutory equipment such as GMDSS. There is also the "SAN-W type," which uses double layers of expanded mesh to enhance attenuation effects, making it suitable for the development and testing of wireless communication devices. 【Features】 ■ Good breathability, making air conditioning and fire prevention systems generally unnecessary ■ Good transparency, making lighting systems generally unnecessary ■ Excellent corrosion resistance ■ Easy to install ■ Self-supporting ■ Can be relocated or expanded *For more details, please refer to the PDF document or feel free to contact us.
