When a shielded room is necessary?
· If your lab is near a broad spectrum emitter (i.e equipment that transmits multiple frequencies under 400Hz), radio tower, mobile phone transmitter or other large field generators, then you should consider a shielded room.
· If your research is in the gamma band and you do not want to use a 60/50Hz notch filter to remove mains power noise, you might consider a shielded room. We recommend taking the steps above to first minimize the mains power noise. If that is not sufficient for your needs, then a shielded room may help.

The room achieves ≥100 dB attenuation across 14 kHz to 40 GHz. With magnetic field attenuation of 85 dB at 14 kHz and 120 dB at 50–103 MHz, and strong performance in the microwave bands (110 dB at 1–10 GHz, 100 dB at 10–20 GHz, and 80 dB at 20–40 GHz), it ensures clean environments for emc testing. Its modular design supports easy assembly, future expansion, and adaptable installation to varying lab configurations.Flexible Configuration for Diverse Testing NeedsThis RF enclosure supports custom room and door dimensions to suit different test setups. It offers optional shielding doors—electromotive, manual, or sliding—equipped with waveguide ventilation windows (300×300 mm), and high-performance power filters for single-phase, three-phase, or DC systems. Additional utilities, such as telephone, air-conditioning, fire-control devices, optical fiber, and CAT5 interfaces, can be integrated without compromising electromagnetic shielding. The structure is shipped in wooden crates with a typical lead time of 2–3 weeks from the Shanghai port.Engineered for Test Integrity and Environmental AdaptationConstructed with cold-rolled galvanized panels connected via CO₂-welded joints and self-supporting frame structure, this room maintains flat, magnetic-free surfaces. It’s built for radiated emission and immunity testing under multiple international standards. The modular format allows quick reconfiguration, supporting expansions or relocations. Delivered completely packaged, it supports reliable EMC test conditions in laboratories or production facilities near strong RF sources like radio towers or broad-field emitters.Product AdvantagesSuperior Shielding Performance Across All Frequency BandsThis RF shielding room provides exceptional shielding efficiency with attenuation levels reaching more than 100dB across an ultra-wide frequency range from 14KHz to 40GHz. It is engineered specifically to meet the highest demands of EMC test laboratories, certification bodies, and manufacturers operating in RF-heavy environments. With verified attenuation levels including 85dB at 14KHz, 100dB at 10–20GHz, and 80dB at 20–40GHz, this enclosure protects against both low-frequency and high-frequency radio interference. Whether used for immunity or emission testing, it offers unmatched emi protection, ensuring that sensitive equipment and test setups remain unaffected by external electromagnetic noise. This consistency in shielding makes it indispensable in environments demanding precise control over emc emi compliance. Customizable and Future-Ready Modular ConstructionUnlike fixed structures, the modular panels—available in 2mm or 3mm galvanized steel—allow the shielding room to be configured, expanded, or relocated without compromising performance. The layout accommodates different room sizes, door types (manual, automatic, or sliding), and interface ports without diminishing electromagnetic shielding efficiency. This ensures high flexibility for labs with dynamic spatial or operational needs. Users can also request ventilation waveguides, filtered power inputs (AC, DC, or 3-phase), and communication interfaces like optical fiber, fire alarm systems, and telephone or network ports. This adaptability makes the product especially suitable for rf shield box manufacturers, system integrators, or facility engineers seeking long-term investment with minimal need for infrastructure overhaul. Fast Deployment with Long-Term Operational ReliabilityWith a delivery time of just 2–3 weeks and pre-packed in protective wooden crates, the RF shielding room offers a hassle-free installation process. The internal structure is built using CO₂-welded cold-rolled galvanized panels that ensure long-term structural integrity, while the non-welded self-supporting frame guarantees zero magnetic interference within the space. Each component is quality-checked for durability and test compatibility, including high-performance emi filters for power lines and optional HVAC-compatible designs. Customers benefit from a cost-effective and maintenance-light shielding system that remains robust even under constant high-frequency usage. The shielding room’s tested performance, compatibility with international standards, and easy integration into existing EMC test labs set it apart in the competitive field of emi shielding solutions.
