Principles of Operation
To accommodate the dual-supply option, the dual-supply manifold on MSA
respirators features two air-inlet ports: a Main inlet and a
Dual-Supply inlet. Both are used to deliver respirable air to the user
whenever connected to a pressurized air source.

With dual-supply capability, users can connect from one pressurized
continuous air source to another without losing continuity of air
flow. When the first of air-supply hose has reached its limit, the
wearer simply plugs into a second approved air source and disconnects
from the first. This technique is known as "leap-frogging" because it
gives workers the ability to move from station to station without
disrupting the supply of air.

Whether a worker is using the "MAIN" inlet of the manifold, the
"DUAL-SUPPLY" inlet or both inlets simultaneously, the respirator will
provide supplied-air respiratory protection as long as the user
remains connected to one of the two air sources.

With the TransportAire System connected to the DUAL-SUPPLY or MAIN
inlet of the manifold, a worker can carry the portable air supply to a
location where the second air source is available for longer-term use.
After connecting the second air source into the open inlet of the
manifold, the user can disconnect the TransportAire System and keep it
available until it is time to exit the area.
