Hyperbaric Oxygen Chamber Product Catalog

LB/YC-Y1J/30 — 1.3 ATA One Seat Integrated

Model: LB/YC-Y1J/30 | Working Pressure: 1.1–1.3 ATA (customizable) | Dimensions: 1360×800×1965 mm | Capacity: 1 person

Constructed from Q355b special compression-rated steel, this hard-shell hyperbaric oxygen chamber integrates the cabin and host into a single assembly, eliminating the need for a separate equipment room. The unit delivers a host oxygen concentration of 93%±3% at a 5L/min flow rate while maintaining dispersion oxygen concentration below 25% for cabin safety, and installs on standard 220V/50Hz single-phase power. Running at 60dB(A), it provides controlled low-pressure oxygen therapy suited to personal and small-clinic use. This configuration is purpose-built for home users and independent health centers seeking a compact, low-footprint hyperbaric unit without dedicated station construction.

LB780-90 — 2.0 ATA One Seat Deluxe

Model: LB780-90 | Working Pressure: 1.1–2.0 ATA | Dimensions: 1400×800×1880 mm | Capacity: 1 person

Built with Q390b special compression steel rated for higher working pressure, this one-seat deluxe pressurized oxygen chamber supports an oxygen flow of 15L/min against a 1500W, 220V/50Hz host drawing 93%±3% oxygen concentration. Its 55dB(A) noise profile and 80KG host unit keep the footprint manageable while sustaining elevated ATA ranges beyond standard 1.3 ATA chambers. The higher pressure ceiling supports faster tissue oxygenation protocols relevant to recovery-focused applications. This model is positioned for athlete and sports-recovery buyers requiring higher-pressure HBOT sessions in a single-occupant format.

LB800-50 — Wheelchair 2.0 ATA

Model: LB800-50 (Wheelchair variant) | Working Pressure: 1.1–1.3 ATA | Dimensions: 2000×1200×1900 mm | Capacity: 1 person (wheelchair-accessible)

Fabricated from Q235 special compression steel, this wheelchair-accessible hyperbaric oxygen chamber is engineered for patients with mobility limitations who cannot transfer to a standard seated position. The 60KG host delivers 10L/min oxygen flow at 93%±3% concentration through an 800W, 220V/50Hz system, while a reduced 45dB(A) noise level improves patient comfort during longer sessions. Direct wheelchair entry removes a major access barrier in institutional HBOT delivery. This unit is designed for clinical and hospital buyers serving patients with reduced mobility or post-surgical transfer restrictions.

Model: LB2400-30 | Working Pressure: 1.1–1.3 ATA | Dimensions: 2000×1800×1900 mm | Capacity: 2 people

This two-seat hard-shell chamber uses Q235 special compression steel and includes two headsets, two mask oxygen tubes, and dual manual/automatic pressure relief valves as standard. The 80KG host sustains 15L/min oxygen flow at 93%±3% concentration on a 1500W, 220V/50Hz supply, with cabin noise held at 55dB(A). Paired-seat delivery allows two patients to undergo simultaneous oxygen therapy sessions without doubling institutional installation cost. The configuration suits clinics and wellness centers managing moderate daily patient throughput.

LB/YC-Y-4 — 1.3 ATA Four Seats Deluxe

Model: LB/YC-Y-4 | Working Pressure: 1.1–1.3 ATA | Dimensions: 2000×3000×1900 mm | Capacity: 4 people

Constructed with Q235 special compression steel at a scaled hull size supporting four simultaneous occupants, this multiplace hyperbaric oxygen chamber includes four headsets and four mask oxygen tubes alongside dual pressure relief valves. The 120KG host maintains 93%±3% oxygen concentration at 20L/min flow on a 1800W power draw, with operating noise at 60dB(A). Group-seat capacity enables simultaneous treatment cycles that reduce per-patient scheduling time in high-volume settings. This model is built for rehabilitation centers managing group therapy programs across larger patient cohorts.

LB/YC-Y-6 — 1.3 ATA Six Seats Deluxe

Model: LB/YC-Y-6 | Working Pressure: 1.1–1.3 ATA | Dimensions: 2200×4200×1900 mm | Capacity: 6 people

The largest cabin in the deluxe line, this six-seat hyperbaric oxygen chamber is built from Q235 compressive resistance steel and ships standard with six headsets and six mask oxygen tubes. Its 140KG host delivers 93%±3% oxygen concentration at 30L/min flow on a 2100W, 220V/50Hz system, running at 60dB(A). Maximum seat count per cabin supports the highest patient-per-session volume in the product line, reducing total unit count needed at scale. This configuration targets commercial wellness operators and large group-therapy facilities requiring maximum throughput capacity.

LB/YC-Y-2 — Wheelchair 2.5 ATA Two Seats

Model: LB/YC-Y-2 | Working Pressure: 1.1–2.5 ATA | Dimensions: 2200×1700×1950 mm | Capacity: 2 people (wheelchair-accessible)

Built from special steel rated for elevated pressure operation, this wheelchair-accessible two-seat chamber reaches 2.5 ATA, exceeding the standard 1.3–2.0 ATA range found in entry-level models. The 80KG host sustains 93%±3% oxygen concentration at 10L/min flow on a 2000W, 220V/50Hz supply, with noise capped at 65dB(A). Elevated ATA capability combined with wheelchair access supports higher-intensity protocols for patients with mobility constraints. This unit is suited to hospital-grade clinical programs requiring both higher pressure ratings and accessible patient transfer.

LB/YC-Y-2 — Wheelchair 3.0 ATA Two Seats

Model: LB/YC-Y-2 | Working Pressure: 1.1–3.0 ATA | Dimensions: 2200×1700×1950 mm | Capacity: 2 people (wheelchair-accessible)

This top-of-range wheelchair-accessible chamber shares the special steel hull construction of its 2.5 ATA counterpart but is rated to the highest pressure ceiling in the current catalog, 3.0 ATA. The 80KG host delivers 93%±3% oxygen concentration at 10L/min flow on a 2000W system, with operating noise at 65dB(A). The 3.0 ATA ceiling accommodates the most demanding hospital-grade oxygen therapy protocols within the product range. This model is positioned for hospital and tertiary-care buyers requiring maximum pressure capability alongside wheelchair accessibility.

LB800-50 — 1.3 ATA One Seat Premium

Model: LB800-50 (Premium) | Working Pressure: 1.1–1.3 ATA | Dimensions: 2000×1200×1900 mm | Capacity: 1 person

The premium one-seat variant uses Q235 compressive resistance steel with a larger 720×640×1500mm engine housing than the deluxe configuration, while maintaining the same 93%±3% host oxygen concentration at 10L/min flow. Standard configuration includes cabin decoration, a customized air conditioner, wireless call system, safety valves, an electric sofa, and a 32-inch LCD TV. The refined cabin finish and entertainment integration improve perceived treatment-room quality during extended sessions. This model targets high-end clinical and wellness spaces seeking a more refined single-occupant hyperbaric oxygen chamber.

LB/YC-Y1J/50 — 1.5 ATA One Seat Integrated

Model: LB/YC-Y1J/50 | Working Pressure: 1.1–1.5 ATA | Dimensions: 1360×800×1965 mm | Capacity: 1 person

Sharing the Q355b special compression steel hull of its 1.3 ATA counterpart, this integrated single-occupant chamber extends the pressure ceiling to 1.5 ATA while retaining the compact 1360×800×1965mm footprint. Standard configuration includes wireless call, one headset and mask oxygen tube, and a combination of manual, automatic, and emergency pressure relief valves. The space-efficient integrated format delivers higher-pressure oxygen therapy without requiring a dedicated host room. This model serves home users and small clinics that need 1.5 ATA capability within a space-constrained installation.
