The UK2 is a NATO AE0054 certified CBRN (formerly NBC) Air filter unit designed for domestic use in emergency shelters such as safe rooms, fallout rooms and inner refuges.

The filter cylinder inside the unit is removeable by hand, and is a heavy aluminium construction.  It contains a HEPA H14 filter with 99.997 % efficiency, to BS3928, for the removal of particulates including biological agents and radioactive particles. Followed by a specially impregnated carbon section that meets NATO standard AEP54 for the removal of Chemical Warfare Agents, radioactive gases and Toxic Industrial Chemicals.  In front of the main filter is a replaceable pre filter. The input and output air connectors are 100mm / 4’’ ducts. This offers a universal wall/ceiling connection for your shelter design, and a directable air flow at the exit.

The unit is mains powered, 240vac, and would need to be powered from a 240vac generator which would be located in a generator room or enclosure in a shelter. Alternatively it could be used with a suitable inverter from a 12VDC power supply, but this would require substantial sized battery pack/s. Modern ‘power station’ batteries with mains outputs and high capacity are particularly suitable.

*Please note that we do not currently offer a blast valve or over-pressure valve, which are usually required for purpose-built bunkers / blast shelters.     It should be noted that there is a large difference between a blast shelter and a fallout shelter.   A blast shelter should be underground and designed to withstand the pressure wave of a nuclear detonation with a minimum of 5 psi.   Blast shelters of 20 and 40psi are typical,  and these require specialist knowledge and professional build skills, along with adequate blast valves.  A fallout shelter on the other hand is a broad term used to describe a shelter that will minimise risk to life from radioactive fallout particles,  be that settled particles that are radiating through materials or air-suspended particles that may be inhaled or ingested.   Such a shelter requires correct distance positioning, as much dense material protection around it as possible and a sealed positive pressure air filter set up, which is the life support system of a shelter.
