I did install the Blast door, but decided not to install the air system. Wife freaked out about having it all air tight in the safe room, lol. This is a high quality system, and I added all the extras, like hand crank if the batteries die. What's included with this package.
The 60 CFM complete system with manual battery backup comes with everything necessary to pull it from the boxes and install it inside an underground shelter. One AC and DC capable 60 CFM Safe Cell. With a complete filter bank, includes a pre-filter set, a nuclear grade HEPA particulate filter, and a carbon adsorber. One wall mount bracket, 2 quick release clamps, 2 star nuts & 4 concrete wedge anchors.
One AC and one DC power cord. One 60 inch chemical resistant flexible air intake hose. With gaskets, concrete wedge anchors, and a masonry drill bit. With both wall and ceiling adapters. One hard copy of the installation and operation manuals.
