SCOTT RIT-PAK III
TO SUPPLY BREATHING AIR TO COMPATIBLE SCOTT PRODUCTS
DESCRIPTION
The SCOTT RIT-PAK III portable air supply is intended for use by a Rapid Intervention
Team (RIT) as an emergency source of breathing air to supply air to a single respirator
being used by one person only while that person is being evacuated from an atmosphere
requiring respiratory protection.
The SCOTT RIT-PAK III portable air supply and its accessories or options are NOT NIOSH
or NFPA approved. The RIT-PAK III portable air supply is intended for only use in conjunction
with a respirator as an emergency air supply source to that respirator to aid in the evacu-
ation of the respirator user from a hazardous environment. The addition of the optional
Emergency facepiece and Emergency breathing regulator provide greater options for use
of the equipment, but the RIT-PAK III portable air supply is not a complete respirator.
This equipment must never be used to supply more than one respirator user at a time. The
RIT-PAK III portable air supply is NOT an air cart nor is it intended for use as a source of
breathing air for routine operations or as a hose line air supply system. Do not use any
additional hoses, adapters, or connectors except as directed by this instruction.
The SCOTT RIT-PAK III portable air supply consists of a combination LOW pressure /
HIGH pressure supply assembly with a single cylinder coupling to attach to a breathing
air cylinder. A carrying bag is used to support and transport the cylinder. The RIT-PAK III
portable air supply is equipped with both LOW pressure and HIGH pressure supplies as
follows:
LOW PRESSURE AIR SUPPLY HOSE with a pressure reducer and low pres-
–
sure hose from the reducer to a dual manifold with both male and female quick
disconnect couplings for a variety of connections to a SCOTT respirator. The
use of these components is covered in the LOW PRESSURE AIR SUPPLY
section of this instruction. Additional ports are provided on the LOW pres-
sure air supply hose manifold for the installation of other quick disconnect
fittings. Refer to the INSTALLATION OF ALTERNATE QUICK DISCONNECT
COUPLINGS section of this instruction for details.
HIGH PRESSURE AIR SUPPLY HOSE* is equipped with a coupling which will
–
fit all respirators in compliance with NFPA 1981 (edition 2002 or later) which
are fitted with a Rapid Intervention Crew/Company Universal Air Connection
(RIC UAC) System. The integral dust cover is used to vent the residual air
pressure from the system after the cylinder valve has been closed. The use of
this feature is covered in the HIGH PRESSURE AIR SUPPLY section of this
instruction.
The SCOTT RIT-PAK III portable air supply is available in three pressure models for use
with the following air cylinders:
• RIT-PAK III 2216 psi for use with SCOTT 2.2 cylinders with an air supply
rated at 30 minutes.
• RIT-PAK III 4500 psi for use with SCOTT 4.5 cylinders with an air supply
rated at 30, 45, or 60 minutes
• RIT-PAK III 5500 psi for use with SCOTT 5.5 cylinders with an air supply
rated at 30, 45, 60, or 75 minutes
The appropriate cylinder and valve assembly must be purchased separately.
The Pressure Reducer Assembly is labeled with the pressure the equipment is designed
to use.
A remote gauge console is provided with an analog gauge showing the total avail-
able air pressure left in the breathing air cylinder as well as an LED DISPLAY
with lights indicating the remaining air in the same format as the heads-up display
found on many SCBA respirators. The remote gauge console is mounted on the
outside of the bag so it is available to view at all times. The pressure reducer is
also equipped with a BELL to signal when the air pressure in the breathing air
cylinder has dropped below one-quarter of full. Depending on how the RIT-PAK III
portable air supply is used, the end-of-service alarm on the respirator may or may
not operate. See the LOW PRESSURE AIR SUPPLY and the HIGH PRESSURE
AIR SUPPLY usage sections of this instruction for recommendations.
