  This system is designed for home use for pressurization of a room, replacing the existing air with safe, clean filtered air to breath incase of a Nuclear or Biological Hazard.
  The system either sits on the floor on installed feet or hangs from your ceiling by bolting to the installed hanging tabs.
A metal flexible duct will attach to the intake side or blower connection while the other end of the flex duct attaches to the blank off plate which will attach over the face of your window case on the room side.
  The system comes with a 16 foot power cord and does not require any wiring, just plug it in and turn on the blower. The blower uses a lighted indicator switch for operation.
Power Outages:
The inverter drive blower allows this system to operate from 120 volt ac to 12 volt with the flip of a switch.

This system has:
1 - 14 & 11 ga. Galvanized Metal casing
2 - All joints (welded/bolted w/water jet cut silicone gaskets).
3 - Fan blower 12 volt inverter drive. (low db operation)
4 - Gasketed filter access doors w/ filter identification label.
5 - Power switch is nema-4 moisture/waterproof with indicator            light and lock out guard to control usage. System comes with       a 20 foot heavy 120 VAC power cord with ul-class 1 plug.
6 - Dwyer Magnehelic pressure differential gages with filter                 change-out flags to measure filter resistance and loading rate       for proper change-out.
7 - Duct connection upstream offers a 12 diameter x 4" extended        collar with a raised rib for clamp installation to prevent duct          blow off. The air outlet has a mesh screen.
8 - Filter Locking mechanism's are cam drive, lever operated from      inside the door opening when the filter access doors are               removed.
9 - Pre-filters are 6" upstream, to remove large dust and particals        from the air flow to prevent the hepa filters from loading to            fast. 2" downstream to remove dusting from the Carbon filters.
10 - Hepa Filters are 99.99 % efficiently Nuclear Grade for airborne      partical removal. Filters are standard size with upstream                sealing gasket attached
11 - Carbon Filters are 12" deep, Nuclear Grade Activated Carbon      which will remove any gaseous material that could be fatal if         ingested.

This system is designed to be ceiling hung or sit on the floor with 6" elevated feet and metal flex duct connecting from the gasketed window blank off plate to the air inlet end or upstream duct connection is sized to fit a standard 12" flex duct and clamp.
