Automatic Ventilation Blower The ASR-50-AB Automatic Ventilation Blower is an optional component that you can install in your underground blast-resistant shelter that will automatically draw air into, and out of your shelter - providing true ventilation. The purpose of this device is to automatically remove moisture, stale air, and odors (and minimize mold and mildew) from your protected space while it is not in use. It does this by drawing air into your shelter - which pressurizes it - and then that air is expelled through the outlet vent. It is easily installed with the included wall mount bracket and the quick-release hose that is included with the Safe Cell is simply pulled off the intake port of the Safe Cell and put on the blower with a slight twisting motion. The timer is set to run for a few minutes every day to automatically ventilate the shelter. In an NBC event, the occupants simply remove the hose from the ventilation blower and install it onto the Safe Cell and then turn on the Safe Cell - this can be done in a few seconds. The blower is a rated for continuous duty and can be used as a backup blower for the Safe Cell. All it takes is to remove it from the mounting bracket with a slight twisting motion and then slip it into the top of the Safe Cell, turn on the switch, and you have a backup blower that will suck air through the internal blower of the Safe Cell and expel safe, breathable air into your protected space.
Shown above is the Automatic Ventilation Blower plumbed into the intake Blast Valve. Note the timer on the electrical outlet that turns the blower on and off at regular intervals to automatically ventilate your blast shelter without loading the filters in the Safe Cell with particulates or moisture. In the picture above, the intake port of the Safe Cell has the red shipping cap installed on it to prevent particulates and moisture from loading the filters in the Safe Cell. This is the normal installation that you should have in your underground shelter - until you occupy it. On the Safe Cell page, you will see the hose connected to the intake port of the filtration system. It literally takes a few seconds to change this connection.
