Overview
In any environment where the air itself poses a threat — whether that’s a chemical plant, an oil refinery, a confined vessel space, or an active fire scene — the ability to breathe safely is not a comfort feature. It is a survival requirement. When atmospheric oxygen levels drop below safe thresholds, or when toxic gases, smoke, or combustion byproducts contaminate the working environment, personnel cannot rely on the ambient air. They need a certified, self-contained supply of breathable air they can carry with them — and they need it to work reliably, without fail, every single time.
The Self Contained Breathing Apparatus (Fangzhan) is a positive-pressure, open-circuit SCBA designed for entry into immediately dangerous to life or health (IDLH) atmospheres. Equipped with a 6-litre compressed air cylinder capable of storing 1800 litres of breathable air, the Fangzhan SCBA provides approximately 60 minutes of respiratory protection under standard working conditions — enough duration for emergency response, evacuation operations, hazardous area entry, and confined space rescue at industrial and marine sites. With a total system weight under 17 kg, the apparatus is engineered for working mobility: wearers can move, climb, and operate tools without the apparatus becoming a burden in itself.
What distinguishes the Fangzhan SCBA within this product category is the combination of a clearly specified low-pressure alarm threshold (50–60 Bar) and the choice of cylinder material — either steel or composite fibre — allowing procurement teams to select the variant that best fits their operational environment, whether weight is a priority or cylinder durability in heavy industrial use is the primary concern. For HSE officers, safety managers, and procurement teams sourcing respiratory protection for fire brigades, emergency response teams, and hazardous environment workers, the Fangzhan SCBA is a practical, field-ready solution backed by measurable specifications rather than marketing claims.
Key Features
6-Litre Cylinder with 1800-Litre Air Capacity
The Fangzhan SCBA is equipped with a 6-litre compressed air cylinder storing 1800 litres of breathable air at rated working pressure. Under standard breathing demand conditions, this provides approximately 60 minutes of continuous use — adequate for most fire response, confined space entry, and hazardous area operational tasks. For field teams, 60 minutes of rated duration is a critical planning parameter: it defines how long a wearer can remain in a hazardous atmosphere before the low-pressure alarm activates, and it sets the operational timeline for any task requiring entry into an IDLH environment.
Low-Pressure Alarm at 50–60 Bar
The apparatus incorporates a low-pressure warning alarm that activates when cylinder pressure drops to the 50–60 Bar threshold. This alarm provides the wearer with a clear, timely warning to begin withdrawal from the hazardous atmosphere while sufficient air reserve remains for safe egress. A well-calibrated alarm threshold is not a minor specification detail — it is the mechanism that prevents a wearer from remaining in an IDLH environment until cylinder exhaustion. The Fangzhan alarm activates early enough to allow orderly withdrawal rather than emergency escape under near-exhaustion conditions.
Choice of Steel or Composite Fibre Cylinder
The Fangzhan SCBA is available with either a steel or composite fibre cylinder. Steel cylinders offer durability and resistance to mechanical damage in heavy industrial environments — they are less susceptible to surface damage from impacts, abrasion, or rough handling during emergency use. Composite fibre cylinders offer a significant weight reduction over equivalent steel cylinders, which matters in applications where wearer fatigue over extended operations is a concern, or where the SCBA will be carried as standby equipment alongside other tools and equipment. Procurement teams can select the cylinder type that matches their operational priorities.
Full-Face Mask with Positive Pressure Design
The positive-pressure demand valve design maintains a slight positive pressure inside the face mask at all times during inhalation and exhalation. This is the critical design principle that distinguishes a proper SCBA from a simpler demand-valve apparatus: positive pressure ensures that if mask seal is momentarily compromised — due to movement, facial hair, or equipment contact — the airflow direction prevents ambient contaminated air from infiltrating the breathing zone. For work in toxic gas atmospheres or active fire conditions, positive pressure face mask design is the appropriate standard for entry-level respiratory protection.
Adjustable Harness and Backplate System
The Fangzhan SCBA uses an adjustable shoulder and waist harness with a structured backplate to distribute the cylinder and regulator weight across the wearer’s torso. At under 17 kg total system weight, the apparatus is designed for donning and extended wear in operational conditions. The harness adjustment system accommodates different body sizes across a workforce, and the backplate design keeps the cylinder stable during movement — important for workers who need to access confined entry points, work on ladders, or operate in restricted spaces where cylinder movement could affect balance or clearance.
Pressure Gauge for Real-Time Air Monitoring
The integrated pressure gauge allows the wearer to monitor remaining cylinder pressure throughout the operation. Real-time pressure visibility is a fundamental operational safety requirement: without it, wearers cannot make informed decisions about task continuation, withdrawal timing, or air-sharing procedures in a rescue scenario. The gauge allows supervisors and entry teams to cross-check cylinder pressure before entry and during multi-person operations where air consumption rates may vary between team members.

Benefits
60 minutes of rated operational duration supports most industrial emergency response and confined space entry tasks. For HSE teams planning safe work procedures for confined space entry, fire response, or hazardous chemical handling, 60 minutes provides sufficient operational time for the intended task plus safe withdrawal — without requiring cylinder swap or standby team deployment for standard-duration operations.
Low-pressure alarm at 50–60 Bar gives wearers actionable warning before air reserve reaches a critical level. This directly reduces the risk of a wearer remaining in an IDLH atmosphere past the safe withdrawal point — a root cause of respiratory protection fatalities in industrial and fire service incidents. The alarm threshold supports safe, orderly exit rather than emergency evacuation under air exhaustion conditions.
Under-17 kg system weight reduces wearer fatigue and supports operational mobility. Emergency response personnel and confined space entry workers are already managing environmental hazards, communication equipment, and task-specific tools. A lighter apparatus reduces the total physical burden, allowing workers to focus on the task and on safe self-monitoring rather than managing apparatus weight and fatigue.
Cylinder material choice supports operational and procurement flexibility. Not every site has the same cylinder handling, storage, and use conditions. Offering both steel and fibre cylinder variants means the apparatus can be specified to match actual site conditions — composite fibre for weight-sensitive applications, steel for environments where cylinder durability during rough handling is the primary concern.
Standardised packaging in a customised plastic carrying case protects the apparatus during storage and transport. SCBA units that are stored in unprotected conditions or transported without proper containment are susceptible to component damage, mask contamination, and regulator misalignment that may not be apparent until the unit is donned under emergency conditions. The included carrying case supports proper storage, transport, and pre-use inspection as part of a structured equipment maintenance programme.
Who It’s For
The Industrial Fire Brigade Team Leader at a Petrochemical or Refinery Site
Your site fire brigade team is responsible for first-response entry into fire, gas release, and chemical spill incidents across the plant. You need SCBA units that your team can don quickly under pressure, that provide clearly specified operational duration for your entry team briefings, and that hold up under repeated use, cylinder refills, and periodic inspection cycles. You need apparatus your team can trust in a real incident — not equipment that looked right on a data sheet but performs inconsistently in the field. The Fangzhan SCBA’s clearly specified 60-minute duration, defined alarm threshold, and choice of cylinder type gives your procurement justification process the objective specification data it needs.
The HSE Officer Responsible for Confined Space Entry Programmes
Your confined space entry programme requires standby SCBA units for rescue team entry and, in some permit classifications, for routine entry personnel where atmospheric monitoring alone is insufficient. You need to specify apparatus that meets your regulatory requirements, document it correctly in your safe work procedure, and ensure that the units available at the permit-to-work point are maintained, charged, and ready for immediate use. The Fangzhan SCBA’s defined cylinder capacity, rated duration, and alarm pressure gives you the documented specification data you need for your confined space entry procedure and risk assessment records.

Accessories and Variants
Steel Cylinder Variant
The steel cylinder variant is recommended for heavy industrial environments where the apparatus may be subject to rough handling, storage in high-traffic areas, or use conditions where cylinder surface damage is a realistic operational risk. Steel cylinders are more resistant to surface impact and abrasion damage than composite fibre cylinders, making them the appropriate choice for applications where cylinder durability in demanding storage and use conditions is the primary specification requirement.
Composite Fibre Cylinder Variant
The composite fibre cylinder variant reduces total system weight compared to the equivalent steel cylinder, making it the preferred choice for applications where wearer fatigue management over extended operations is a priority — including fire service, prolonged confined space work, and offshore emergency response applications where personnel may need to carry additional equipment alongside the SCBA.
Spare Cylinders and Cylinder Refill Service
For sites operating multiple SCBA units across a shift, maintaining a supply of spare charged cylinders allows rapid cylinder exchange during extended operations without requiring the wearer to exit the hazardous zone for the full duration of a cylinder refill cycle.
