High powered, robust, and fitted with an advanced failsafe system to ensure continued operation in the event of mains failure, the CastellexAir 3100 NBC system provides up to 300 m3/h of fresh air to a maximum of 30 people in an enclosed environment. This is a positive pressure air filtration system, which repels contaminated air by elevating the local air pressure until it is greater than the pressure of the air outside. Incoming air—required to replenish the oxygen in your panic room, nuclear bunker, or bomb shelter—is cleaned by the pre filter and a top-rated HEPA filter (not included), ensuring a safe environment in the event of nuclear, biological, and chemical (NBC) attacks.
This fallout shelter air filter operates with 99.99% efficiency for particles down to 0.3 microns (micrometres). Power-rated at 150 W when using the supplied 110/240 V AC power cord or backup supply, the system operates at a conservative 61dBA noise level (just over the average sound level of normal conversation) at 50 Hz.
Perfect as a base-level bunker ventilation system for heavy-duty protection, the Castellex Air3100 life support system (LSS) can also be customized with a number of add-ons. Add blast valves to augment the system’s existing blast-protection capability (the Castellex Air 3100 is supplied with a blast valve able to manage air-pressure fluctuations up to 129psi). Install with an automatic power generator for extra failsafe capabilities. Fit carbon and HEPA filters for complete protection against all known warfare gases plus biological agents, radioactive pollutants including radioactive iodine, volatile organic compounds, and more. Other available accessories include O2 indicators, pressure indicators, HVAC units.
Install your Castellex Air 3100 underground bunker ventilation system in high-risk domestic locations, military applications such as gunboat citadels, and civic or commercial buildings—such as embassies—at extreme risk of compromise or attack. With a 3000 series filter pack fitted (pre filter, carbon filter, and HEPA filter) in the unit, your premises or mobile asset will be superbly protected in the event of a terrorist attack, wartime event, or natural disaster.
