The HAOZHUO RF Shielding Room Cabinet – Model HZ-40GHz is a high-performance modular shielding solution designed to isolate sensitive equipment from radio frequency interference (RFI), electromagnetic interference (EMI), and broadband noise. Engineered with advanced copper shielding layers and fully sealed interfaces, this RF shield room delivers over 100dB of attenuation across a wide frequency range (14kHz to 40GHz), making it ideal for MRI installations, EMC compliance testing, medical environments, and high-frequency industrial labs.
Constructed using galvanized steel with optional copper plating and seamless screw-bolted joints, the shielding cabinet forms a true Faraday cage. Each modular panel is fabricated with high-tolerance laser cutting and engineered seams to ensure zero leakage. Shielded doors, copper mesh seams, and gasketed cable feed-throughs preserve shielding continuity throughout the enclosure. Filter penetration panels are pre-installed for integrating power line filter units, RFI filter blocks, and low pass filters—delivering clean energy to internal systems while isolating noise from the outside.
This EMI shielding room includes built-in EMI power line filters rated from 16A up to 63A, suitable for AC and DC power applications. All ports are tested for stopband attenuation exceeding 100dB and feature line-to-line and line-to-ground isolation. The system supports flexible add-ons, including waveguide air vents, signal entry plates, fiber pass-throughs, exhaust ports, and flame retardant acoustic panels. This highly customizable configuration ensures compatibility with MRI shielding systems, rf shield boxes, rf shielding foil applications, and EMI/RFI sensitive labs.
The HAOZHUO shielding enclosure complies with CE and RoHS standards and is tested per MIL-STD-285, IEEE-299, and NSA 94-106 for shielding effectiveness. Designed and manufactured by Changzhou Hezi International Trading Co., Ltd., this rf shield room reflects over a decade of EMI engineering expertise and is exported worldwide with over 90% international deployment rate.
The cabinet achieves over 100dB shielding effectiveness from 14kHz to 40GHz, providing robust protection against all known EMI/RFI signals. High-frequency noise, mobile signal interference, electromagnetic radiation, and wireless transmission disruptions are all mitigated. This ensures your critical equipment—from MRI machines to EMC testing analyzers—operates in a stable and interference-free environment.
Built from prefabricated modular panels, the rf shield room is easy to assemble, dismantle, relocate, or scale. Whether for small shielded enclosures or large diagnostic suites, the configuration is customizable to accommodate space constraints, internal ventilation, access points, and cable routing. Prefabricated copper rails, flexible filter panels, and interlocking joints reduce labor time and enable rapid field setup without compromising integrity.
Embedded low pass filters, emi power line filter units, and power line noise filter arrays are fitted directly to the cabinet’s penetration ports. These filters are engineered to block noise above the cutoff frequency while maintaining signal fidelity for essential power inputs. The system supports single-phase, three-phase, and DC voltage lines with current capacity up to 63A. All components are compliant with industrial safety standards (UL, CE, VDE, CSA).
The rf shield room includes shielded doors with mechanical locks, copper mesh ventilation systems, and filtered data ports. Waveguide air vents ensure sufficient airflow while maintaining shielding effectiveness. Additional penetrations for exhaust systems, fiber optics, fire suppression, and signal conduits can be provided upon request. Each port is designed with shield continuity in mind, with overlapping copper interfaces or gasketed sealing to eliminate RF leakage.
Every cabinet is manufactured to strict QA standards and undergoes full-spectrum attenuation testing using spectrum analyzers, digital LCR bridges, and interference intensity meters. Our customers span over 100 enterprises globally, including MRI manufacturers, military contractors, and EMC compliance laboratories. With 10+ years in EMI engineering and an export rate above 90%, HAOZHUO has become a trusted name among RF shield box manufacturers and rf shield room solution providers.
All structural and electronic components are built to withstand high-temperature, high-humidity conditions. Panels are corrosion-resistant, non-flammable, and backed by a full 2-year international warranty. From design to after-sale support, we ensure your shielding infrastructure remains effective and compliant for years.
