These tables define the air pressure ranges necessary to provide the GenVX with a volume of air that falls within the required range of 6-15
or 170-425 lpm according to U.S. Government Regulations (42 CFR, Subpart J, 84.150, Table 8). First, find the table with the correct flow
control device, then find the air supply hose length, the value within the corresponding box represents the proper operating air pressure.
