Two different
types of isolation rooms may be created with this equipment
One way to create a containment for use by your family
during an emergency is be closing off the entrance doorway and windows
in the room with a sheet of plastic and duct tape creating a
containment.
Depending on the nature of the emergency
you will want to create either a positive or negative pressure
environment.
If you are trying to keep airborne contaminants out of the room you
will need to create a positive pressure within the room so that when a
door is opened the positive pressure will not allow any air from outside
to enter the room.
If you are trying to keep airborne contaminants in the room from
escaping to the rest of the house you would need to create a negative
pressure so that when a door is opened the outside air will enter the
room and keep any air from the room from escaping.
To create negative pressure inside the
containment,
more air has to be exhausted out than leaks into the containment..
Install the Intake Manifold on the outlet side of the
machine and
connect the flex hose to the outside. All the air exhausted to the
outside is treated by the HEPA filter. The plastic walls
of the containment will be bowed in, indicating negative pressure. By
increasing fan speed, the pressure inside the containment becomes less
than the outside pressure. As the doors to containment open, the
pressure will temporarily change and return to normal when the
doors close. The higher the speed, the faster the room will return to
desired pressure. As the HEPA filter loads with dust, the speed will
have to be increased to reach the same airflow and to maintain the
desired pressure inside the containment.
To create positive pressure inside the
containment, more air has to be pumped in than
leaks out.
Install the Intake Manifold on the
outlet side of the
machine and connect the flex
hose
to the containment.
The outside air is pulled through
primary/secondary filter under a negative pressure. This prevents
leakage of untreated air into the containment. Then the air passes
through blower where it is pushed through the HEPA filter to remove any particulates. The pure air
stream, diffused by the HEPA filter, is then exhausted into the containment . The
plastic sides of the containment should be bowed out to indicate
positive pressure. The speed of the machine can be adjusted to meet your
required number of air exchanges and the positive pressure.
