Shelter Example
The unit is placed outside the Isolation
shelter, the large air "intake" duct is
connected to the shelter duct port. A
small intake duct is supplied to the anti-
room and provides a slight negative
pressure to the ante-room.
The large exhaust duct is routed from
the PASS exhaust and is vented to the
outside to create negative pressure for
the room.
