Castellex Air 3300

The Castellex Air 3300 is a high-capacity NBC air filtration station with pre-installed filters. It fills the gap between the compact Air 550 systems and the industrial-scale CBRNX series: it suits larger shelters and medium-sized bunkers, where the Air 550 no longer has the capacity and a full CBRNX system would be excessive.

The system carries a top-rated H14 class HEPA filter, an F9 class pre-filter and a carbon filter impregnated with activated carbon. Three-stage filtration gives 99.99% efficiency and supplies 300 m³/h of fresh air for up to 30 people.

150 W of power lets the system run hard and long. Triple reliability comes from the power unit, a high-capacity backup battery and a 2.6 kW backup generator — the system keeps working even if both the mains and the battery fail.

Harmful particles down to 0.3 micron are held in a hermetically sealed unit so they can later be disposed of safely.
