Hand Operated Air Pump for the NBC Air Filtration System
Mount this hand operated air pump on the wall above the NBC Air Filter at a convenient height and it is operated by turning the handle. It is used to draw filtered air into a protected space during a long term power outage.
Turning the hand crank at 60 revolutions per minute (RPM) will give a blower output of 250 cubic feet per minute (CFM). When attached to the NBC Filter, the bank of filters imparts a resistance to the airflow that reduces it to a complete system output of 60 CFM.
This hand cranked blower may be mounted in any position and features solid steel gears made from A-36 steel, riding in heavy duty oil-lite impregnated bronze bearings, 1/8-inch thick steel side plates for the gearbox cases and blower housings made from ABS with a matched high velocity forward curved impeller made from Dielectrite 44-10 HG .
One Hand Crank Pump.
One section of hose.
Four concrete wedge anchors.
One hard copy of the Manual.
