A panic room, bunker, or bomb shelter only goes part of the way to protecting your family and possessions. In the event of a nuclear, biological, or chemical attack, you need to be able to control the environment inside your protected space. Castellex fallout shelter ventilation systems are built to give maximum peace of mind. They will operate efficiently in critical situations, and provide permanent protection for everyday installations such as homes in areas with a high allergen or pollution count.

By creating a positive air pressure within the protected area, your Castellex nuclear, biological, and chemical (NBC) filtration system makes it impossible for tainted air to enter the room without passing through the ventilation unit: a system of filters working at 99.99% accuracy to remove particles down to 0.3 microns (micrometres), thereby achieving the highest possible H14 HEPA rating. Power consumption is efficient and operational noise is kept to a minimum even in our most powerful models, which are capable of providing 500 m3/h for up to 55 people—at a noise level only slightly higher than conversational speech.
