The quick-release pressure reducer is a critical pneumatic component in SCBA systems, designed to stably reduce high-pressure air from the cylinder to an intermediate pressure and directly connect to the demand valve via a quick-release coupling. Its compact structure and ease of operation significantly enhance donning efficiency and operational flexibility.
- Features an integrated precision mechanism with a piston-type regulator, ensuring stable output pressure regardless of cylinder pressure fluctuations or user breathing rate.
- Equipped with a standard quick-connect coupling on the outlet for one-push connection/disconnection with the demand valve, providing secure sealing and tool-free assembly.
- Inlet compatible with international standard cylinder valve threads (e.g., G5/8, M18×1.5) for various carbon fiber cylinders.
- Built-in safety relief valve automatically activates if output pressure exceeds safe limits, protecting downstream components and the user.
- Housing made of high-strength aluminum alloy with anti-corrosion coating, offering light weight, durability, and impact resistance.
- Operating temperature range: -30°C to +60°C, suitable for harsh environments.
1. Rapid Connection: Quick-release design allows instant locking upon insertion and quick release without twisting, dramatically reducing preparation time.
2. Stable Output: Precision regulation ensures output pressure fluctuation ≤0.2 bar across 0–300 bar input range, providing smooth breathing.
3. Reliable Safety: Dual protection with overpressure relief valve and rupture disc prevents accidents.
4. Lightweight Construction: Weighs only 300 grams, minimizing user burden.
5. Easy Maintenance: Modular design allows quick disassembly for cleaning or seal replacement, lowering maintenance costs.
Widely used in firefighting, industrial rescue, petrochemical, marine, mining, and other scenarios requiring rapid SCBA deployment.
