Capable of providing 500 m3/h of fresh air for 55 people, the Arcadia Air 3500 nuclear, chemical, and biological (NBC) filtration system delivers superb protection and environmental control for panic rooms, military installations and citadels, nuclear fallout shelters, survival bunkers, and mobile real estate such as villas, luxury yachts or warships. Highly recommended for embassies, hotels, schools, government buildings, and other at-risk targets, its high 250 W power rating allows the system to operate reliably in large areas at an incredibly low noise level of 62dBA The system’s three filters are capable of removing every known warfare gases, plus biological agents and nuclear material including radioactive iodine. Harmful particulate matter down to 0.3 microns (micrometers) is scrubbed from the air and held in a hermetic enclosure until it can be safely disposed of. The Arcadia Air 3500 LSSis a complete NBC filtration solution with the capability to support communications devices and control environmental temperatures. This underground bunker air filtration system boasts a cooling and heating (HVAC) unit as well as an O2 indicator and system status indicators. You will be able to monitor and control the ambient temperature, keep an eye on the breathability of the air in the room, and check the operability of the system itself. Four USB ports are built into the system, enabling constant charging for communications devices such as smartphones. A mains socket may also be added to the unit as an optional extra, enhancing your support capacity by providing a power outlet in the event of mains shutdown.
