Commercial-Grade NBC and CBRN Systems

Castellex commercial-grade NBC (Nuclear, Biological, and Chemical) and CBRN (Chemical, Biological, Radiological, and Nuclear) air filtration systems are designed for large fallout shelters, bomb shelters, and bunkers. CBRN systems require professional installation and are best suited for purpose-built shelters to ensure full protection and optimal performance.

An exception is the Air Series NBC air filtration systems, which are designed for easy, DIY (do-it-yourself) installation. These systems come as complete, ready-to-install kits that include the NBC filtration unit, blast valve, blast-protected overpressure valve, piping, and fittings—allowing users to set them up without specialized assistance.

The Air Series—including models and variations like Air350, Air550, and Air3500—is ideal for protecting smaller groups, such as families, small work teams, or several neighborhood families. Known for being highly user-friendly, these units are simple to install, operate, and maintain, making them some of the most accessible NBC/CBRN systems available.

Their versatility allows installation in: Fallout shelters, Living containers, Bomb shelters, Containerized Housing Units (CHUs), Containerized Living Units (CLUs), Converted shipping containers, Military enclosures, Mobile units, Temporary shelters

They can also retrofit existing spaces, like basements or root cellars, transforming them into functional fallout or bomb shelters. The Air Series offers flexible protection for both permanent and temporary setups while prioritizing ease of use, DIY installation, and accessibility.
