ALLEGRO
Frequently asked questions
Common questions about ALLEGRO from 3G Electric.
What is the operating pressure range for Allegro supplied-air respirator (SAR) assemblies?
Allegro partial SAR assemblies operate at different pressures depending on the model and configuration. For example, the 9815 series breathing air blower with EF couplers operates at 2.5 psi, while the 9904 series general-purpose assembly with an ambient air pump delivers 15 psi. Another 9904 series half-mask assembly operates at 12 psi. These pressures are specified for the ambient air pump used with the respirator. It is important to match the pump output to the respirator's requirements to ensure proper airflow. The fittings, such as OBAC or Parker EF couplers, are also specified for each assembly. When selecting a system, verify the pressure and fitting type against your existing air supply and respiratory protection program.
What components are included in the Allegro Bitrex fit testing kit?
The Allegro Bitrex fit testing kit (MPN 2041) includes nebulizers and test and sensitivity solutions. The kit uses the Bitrex fit testing protocol, which involves a bitter-tasting aerosol to detect leaks in a respirator's seal. The fluid volume for the solutions is 2.5 cc. This kit is used to verify that a respirator fits properly by detecting any leakage through the facepiece seal. The kit is designed for occupational health and safety professionals who conduct qualitative fit testing. Replacement parts, such as additional nebulizers or solutions, are also available. The kit is referenced against OSHA standards for fit testing. Users should follow the manufacturer's instructions for proper administration and maintenance of the kit.
What are the specifications of the Allegro SCBA storage bracket?
The Allegro SCBA storage bracket (MPN 4111-06) is a steel bracket with a yellow finish. It includes a 6-3/4 inch clip and has an overall length of 20-1/2 inches and a width of 4 inches. This bracket is designed for storing self-contained breathing apparatus in industrial facilities, providing a secure mounting point for quick access. The steel construction offers durability, and the yellow color enhances visibility. The bracket is intended for wall or surface mounting, and the clip holds the SCBA in place. It is a component within a larger respiratory protection program, ensuring that equipment is stored properly when not in use. Installation hardware may be required and is not included unless specified. Verify the dimensions against your SCBA cylinder and mounting location.
What is the purpose of the Allegro airline temperature controller?
The Allegro airline temperature controller (MPN 9990) regulates the temperature of air supplied to a supplied-air respirator (SAR) system. It features a 1/4 inch stainless steel Hansen plug and belt, and is constructed of aluminum. This controller is used in SAR systems to adjust the air temperature for user comfort, particularly in environments with extreme heat or cold. It connects to the airline via the Hansen plug and can be worn on a belt. The aluminum construction keeps the unit lightweight. The controller is part of the 9910 series of partial SAR assemblies. It is important to ensure compatibility with your existing SAR system, including the fittings and air supply pressure. Regular inspection and maintenance are recommended to ensure proper function.
What types of respirators are available in the Allegro 9904 series?
The Allegro 9904 series includes partial supplied-air respirator assemblies with different configurations. The 9904 general-purpose assembly consists of a helmet with a Stedprene neck cape, OBAC fittings, and an ambient air pump delivering 15 psi. The 9904-W is configured for welding applications and includes a helmet with a Stedprene neck cape and OBAC fittings, also powered by an ambient air pump. Another variant, MPN 9920, is a half-mask assembly with a silicone rubber seal operating at 12 psi using OBAC fittings. These assemblies are intended for general industrial use where respiratory protection is required, but they are not for IDLH (immediately dangerous to life or health) environments. Each assembly requires a compatible air supply and should be selected based on the specific hazard and task.
What is the function of the Allegro flow adapter in SAR systems?
The Allegro flow adapter (part of the 9910 series) is used to connect a cold or cool air supply to a supplied-air respirator. It has a gold finish and dimensions of 2 inches width, 3 inches height, and 3 inches length. This adapter allows the user to route conditioned air into the respirator system, which can improve comfort in hot environments. It is a component within the 9910 series of partial SAR assemblies. The adapter is constructed to interface with standard fittings, ensuring compatibility with the rest of the SAR system. When installing, verify that the adapter matches the air supply hose and respirator inlet. It is a replacement or upgrade part that should be installed according to the manufacturer's instructions.
