National Shielding: A Leader in EMI Filter and Shielding Solutions

 National Shielding, Inc. is a family-owned and veteran-owned company based in Dallas, Texas, specializing in the design, manufacture, and installation of radio frequency (RF) and electromagnetic interference (EMI) shielded enclosures. While their core business is building RF shielded enclosures, these enclosures are designed to contain and block a variety of electromagnetic noise, including EMI, and often incorporate specific EMI Filter Manufacturer components.

The company's expertise stems from its founders, who have over 50 years of combined experience in the shielding industry. Their approach is centered on a commitment to quality, a small business culture, and direct communication with clients to ensure a successful outcome for every project. National Shielding serves a wide range of industries, including medical, military, government, and industrial sectors.

Products and Services

National Shielding's primary products are Faraday cages, which are enclosures designed to block electromagnetic fields. They offer a variety of shielding solutions to meet different client needs and specifications.

RF Shielded Enclosures: The company designs and manufactures both modular steel panel and copper enclosures. These are used for applications that require a secure environment free from external electromagnetic interference, such as MRI rooms, secure communication rooms, radar repair facilities, and police evidence rooms.

MRI Shielding: A significant portion of their work is focused on creating shielded rooms for magnetic resonance imaging (MRI) scanners. MRI machines are highly susceptible to EMI and require a copper or steel Faraday cage to function correctly. National Shielding provides both the RF shielding and the magnetic shielding necessary to contain the powerful magnetic fields generated by these machines.

RF Shielded Components: In addition to full enclosures, National Shielding provides various components to ensure the integrity of a shielded room. This includes shielded doors, windows, and Emi shielded enclosures for electrical power, which are critical for preventing EMI from entering or exiting the enclosure through power lines.

Design, Installation, and Repair: Beyond manufacturing, the company offers comprehensive services. They provide design consultation to create a shielding plan that meets project specifications, and their own trained installation crews, who are direct employees, perform installations throughout the United States and North America. They also offer repair and testing services for existing shielded enclosures, including those installed by other manufacturers.

EMI Filters and Their Role

An EMI filter is an essential component in many shielded applications. It's a passive electronic device used to suppress unwanted electromagnetic noise, or EMI, on a signal or power line. EMI can be both conducted (traveling along a wire) and radiated (traveling through the air). EMI filters are specifically designed to combat conducted EMI, ensuring that a clean power source enters the shielded environment.

The manufacturing of EMI filters is a specialized process that involves the careful selection and assembly of components like capacitors, inductors, and resistors to create a circuit that effectively blocks high-frequency noise. These filters are a vital part of the overall shielding system, as a single unshielded penetration—like a power cable—can compromise the entire enclosure's effectiveness. By providing and installing these filters, National Shielding ensures that their Faraday cages offer complete protection from electromagnetic interference.

MRI Magnetic Shielding: Why It Matters for Safe and Effective Imaging

 When it comes to advanced medical imaging, precision and safety are everything. Modern hospitals and diagnostic centers heavily rely on MRI magnetic shielding to ensure their imaging systems deliver clear, accurate results without interference. Magnetic Resonance Imaging (MRI) machines are powerful tools, but they also create unique challenges due to the strong magnetic fields they produce. Without proper shielding, these fields can impact surrounding equipment, disrupt signals, and even compromise patient safety. This is why specialized shielding solutions have become a necessity, not just an option, for any facility running MRI systems. Understanding MRI and Its Challenges MRI technology uses a strong magnetic field along with radio waves to create detailed images of organs and tissues inside the body. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it safer for patients. However, the very strength that makes MRI powerful also creates challenges. The m...
