Two-Cylinder Marine Air Breathing Apparatus Set with Full Face Mask
وصف المنتج:
إن RHZKF-6.8×2/30 هو two-cylinder self-contained breathing apparatus (SCBA) set designed for marine emergency response and other hazardous environments where smoke, toxic gas, steam, or oxygen-deficient air may be present. Supplied as a complete set with full face mask, harness, cylinders, pressure reducer, pressure gauge, and alarm system, it is intended to provide reliable respiratory protection for trained personnel during shipboard firefighting, rescue entry, inspection, and emergency operations.
هذا marine air breathing apparatus stores compressed air in two 6.8L cylinders at 300 bar, providing a total air storage capacity of 4080L. The positive-pressure breathing system helps maintain safer breathing conditions inside the mask and supports effective use in contaminated atmospheres.
It is widely used in shipboard emergency response, shipbuilding, chemical handling, petroleum, metallurgy, power plants, warehouses, laboratories, mines, and rescue operations where respiratory hazards exist. For marine projects requiring compliance marking, the published model and certification details should always match the actual supplied product documents.

مبدأ العمل
Compressed air stored in the cylinders passes through the cylinder valve and pressure reducer before entering the air supply system connected to the full face mask. The reducer lowers the cylinder pressure to the required medium-pressure level, and the demand valve supplies air according to the wearer’s breathing needs.
When the user wears the mask and opens the system, the apparatus delivers breathable air into the mask and maintains positive pressure to help reduce inward leakage from the outside environment. Exhaled air is discharged out of the system through the exhalation structure.
When cylinder pressure falls to the preset alarm range, the warning device activates to remind the wearer to leave the hazardous area. The manual supplementary air function should only be used when necessary or during inspection.

الأسئلة الشائعة
1. Why choose a twin-cylinder SCBA instead of a single-cylinder unit?
A twin-cylinder set provides a larger total air reserve, which is better suited to longer shipboard emergency tasks and high-risk entry work.
2. What is the working pressure of this marine SCBA set?
This model is listed with a 300 bar working pressure and a 50–60 bar low-pressure alarm range.
3. What is included in the complete SCBA set?
The set typically includes the cylinders, full face mask, harness, pressure reducer, pressure gauge, hoses, and alarm device.
4. Is this SCBA suitable for marine emergency response?
Yes. It is intended for shipboard environments where smoke, toxic gas, steam, or oxygen-deficient air may be present.
5. Can this unit be used outside marine applications?
Yes. It is also suitable for rescue, inspection, and respiratory protection tasks in industrial and hazardous gas environments.
