Product Category: | Diving Equipment |
Brand Name: | SSME |
Country of Origin: | China |
Model Number: | SSDR01 |
Function: | Air Supply |
Application: | Diving |
The SSDR01 First Stage Regulator is the core decompression component of diving respiratory systems. It reduces high-pressure air (200-300 bar) from diving cylinders to medium-pressure air (135-145 psi), supplying stable air to secondary regulators (masks) and buoyancy control devices (BCD)—critical for safe deep-water diving.
• Piston-type structure for stable performance in deep water (≥50m).
• Metal construction (brass + stainless steel) for exceptional durability.
• Low-temperature resistance (≤10℃) for polar or deep-cold diving.
• Low maintenance cost (20-30% cheaper than diaphragm-type regulators).
• Deep-Water Adaptability: Precisely controls medium-pressure output in water depths over 50m, avoiding pressure fluctuations that cause breathing discomfort.
• Outperforms Diaphragm Types: No response delays under high pressure—common in diaphragm regulators—ensuring consistent air supply during intense dives.
• Material: Copper plated with chromium (outer) + brass/stainless steel (inner piston)—resistant to corrosion from saltwater and wear from frequent use.
• Low-Temperature Performance: Piston structure is minimally affected by cold; no hardening of components (e.g., diaphragms) in water ≤10℃, eliminating sealing or decompression failures.
• Large Flow Response: Quickly increases air supply during intense exercise (e.g., fighting currents) or emergencies, no “breathing stalling.”
• Simple Structure: Fewer moving parts for easy disassembly/cleaning; no need to replace elastic diaphragms (unlike diaphragm-type regulators), cutting maintenance costs by 20-30%.
For commercial divers inspecting ship hulls or underwater pipelines (50-100m deep), the regulator’s stable pressure output prevents oxygen toxicity or nitrogen narcosis caused by air pressure inconsistencies.
In polar diving expeditions or deep-cold marine environments (e.g., Northern Atlantic), the regulator’s low-temperature resistance ensures reliable operation without additional heating devices.
For daily diving missions (e.g., underwater construction, salvage), the regulator’s durability withstands frequent use (100+ dives/year) and minor impacts, reducing equipment replacement frequency.
