3M Respirator Capacity
The 3M filter and regulator panel is supplied with quick-disconnects at the outlet for connection of
up to eight (8) supplied air respirators. The actual number of respirators that may be connected to
the 3M filter and regulator panel is dependent on the inlet pressure to the panel and the airflow and
pressure requirements of the respiratory protection. (Fig. 2) As the air passes through the panel
there is resistance to flow called pressure drop. The more airflow through the filter and regulator
panel, the greater the pressure drop. The air control devices approved for use with the
3M respirators must be operated within the supply pressure ranges and hose lengths stated in their
User Instructions
. Use Figure 2 along with information on the maximum airflow consumption,
supply pressure ranges, and approved hose lengths as stated in the
User Instructions
for the 3M air
control device to determine the number of respirators of a specific type that may be connected to
the panel.

Discussion on Respirable Air
Many older compressed air systems may have air that is unfit for human use without secondary air
treatment. This is due largely to the presence of objectionable oil vapors and odors. Rules and
regulations governing air quality when using compressed air for respiration are quite specific.
Precautions must be observed when using compressed air for breathing purposes.
