DESCRIPTION
The point of attachment box for the MSA Breathing Air Distribution System (BADS) permits up to four NIOSH-approved
airline respirators to be connected to a single source of breathing air.
The point of attachment box is approved for use in a portable or stationary position.
The system consists of:
•
Particulate / Bulk Liquid Separation Filter Element
• Manual Drain
• Filter Change Indicator
• Removes 95% bulk particulate and liquid @ 5 microns
•
Pressure regulator can be adjusted until the desired pressure for the respirator is reached with 0-125 psi limitations.
•
Pressure gauge operates in 0-125 psi range
•
4-outlet manifold
•
Relief valve at 125 psi with manual pull ring.
•
The female inlet is 1/2" NPT with 1/2" industrial interchange plug so the user can attach a breathable air supply
source.
•
Four outlet fittings:
• units can be ordered with MSA Union Adapters, P/N 69542, (Male 3/4 inch -16 UNF going into a 1/4" NPT female
manifold thread), to connect directly to MSA NIOSH-approved breathing hose or MSA locking quick-disconnects
and hose. See section on accessories. The union adapters can be removed and replaced with any suitable fitting
with a 1/4" NPT male thread. The manifold has a 3/8" to 1/4" NPT brass bushing. However the union adapter
(P/N 65942) is necessary to make connection to MSA breathing hose.
• Units can be ordered with aluminum Snap-Tite quick-disconnect cockets, steel Foster quick-disconnect sockets,
and brass Hansen quick-disconnect cockets. (See Parts List).
•
Protective carrying case is constructed of durable corrosion resistant materials with pressure equalization valve so the
case can be opened after exposure to a change of atmospheric conditions.
SPECIFICATIONS

BREATHING AIR SUPPLY
•
The responsibility of the quality and quantity of breathing air rests with the user. Users must
comply with all federal, state, or local regulations.
•
The air quality supplied to the Breathing Air Distribution System must meet the air quality
requirements of ANSI Z86.1-1973 (Compressed Gas Association Specification G-7.1 for Type 1,
quality verification level (grade) D Gaseous Air). Copies of the specification are available from
the American National Standards Institute or the Compressed Gas Association. The air must be
within the carbon monoxide allowed limits and some means of monitoring CO may be required
as per NIOSH approved airline respirators (see 29 CFR Part 1910.134).
•
The air source must supply the proper flow at the proper pressure for all the respirators
connected to the system. The inside diameter of the air source hose must be of large enough
size not to restrict flow to the system. The air flow and pressure requirements may be found in
the respirator's NIOSH approval. This approval is included in the instructions supplied with
each respirator from MSA.
Failure to follow this warning can result in serious personal injury or death.
