The route into the building
Check entrances, lifts, corridors and delivery access against the manufacturer’s installation plan. Confirm who will arrange handling and assembly.
Four chambers. One to four seats.
Compare the equipment.
Plan your installation.
Specify a seated FINK FESL chamber for your clinic, hospital, hotel or home. All four models deliver 100% medical oxygen by mask at up to 2.0 ATA. We work through the model, room, oxygen supply and installed budget with you.
Compare the four models.
Every FESL works the same way. You sit in a chair, the cabin is pressurised with air and you breathe 100% medical oxygen through a mask at up to 2.0 ATA. The difference is how many people it seats and how much room it needs. All four are modular, so they come in through standard doorways and are assembled in the room.
| Model | Seats | External dimensions | Chamber footprint | Weight |
|---|---|---|---|---|
| FINK FESL-310 (Solo) | 1 | 2.0 × 2.3 × 2.2 m | 4.6 m² | 1,300 kg |
| FINK FESL-322 (Duo) | 2 | 2.67 × 2.3 × 2.2 m | 6.1 m² | 2,000 kg |
| FINK FESL-323 (Trio) | 3 | 3.53 × 2.3 × 2.2 m | 8.1 m² | ~2,900 kg |
| FINK FESL-324 (Quad) | 4 | 4.29 × 2.3 × 2.2 m | 9.9 m² | 3,300 kg |
Chamber footprint excludes access, operator space and supporting equipment. The required room size is confirmed during installation planning.
What all four share
- Treatment: 100% medical oxygen by mask, at up to 2.0 ATA
- Chamber rating: 2.8 ATA operating, 3.0 ATA design, to ASME PVHO-1 2023
- Door: sliding, 700 × 1,416 mm
- Safety: fire deluge system, UPS backup power, emergency depressurisation inside and outside
- Oxygen: cylinder manifold with automatic changeover
- Windows: two 695 mm viewports
The chamber is rated above the treatment pressure. That margin is part of the code, not a treatment setting. Your doctor sets the pressure for each session.

Cleared by the FDA. Built to the full code.
The one- to four-seat FESL chambers (FESL-310, 322, 323 and 324) are supplied under FINK's FDA 510(k) clearance K240569, granted on 21 November 2024, as prescription medical devices for the 13 conditions listed in the clearance. The FDA summary describes FINK's chamber family by compartment rather than by seat count, which is why it mentions capacities of four to 28. We send the clearance letter with every proposal.
Built to ASME BPVC Section VIII Division 1, ASME PVHO-1 and NFPA 99. Read the FDA clearance · FINK standards.
Compare chamber categoriesInstallation and site requirements.
The chamber is one part of the installation. Establish who is responsible for each part of the project before placing an order.
The room & structure
Have the installation team assess floor loading, clearance, ventilation, temperature and service access. External dimensions alone do not establish the room size you need.
Oxygen & electrical supply
Agree the specified medical oxygen supply, storage arrangements and electrical requirements with the project team and local suppliers.
People & permissions
Confirm local requirements, medical oversight, operator training and emergency procedures. Agree who will commission the system and sign off its use.
What does a FINK chamber cost?
Most seated FESL projects come in between USD 300,000 and 600,000 installed. Where yours lands depends on the number of seats and the fit-out. The written quote for your site sets the final figure, including delivery, import and any building work.
Exact model prices are available on request. Tell us your seats, setting and country for a written project budget.
Ask for these items separately
- Chamber model, seating and included equipment
- Freight, insurance, import charges and local delivery

This is a comparison checklist, not a statement that every item is included.
Explore the full buying guideTraining, maintenance and support to confirm.
Ask who will maintain the chamber in your country, what the warranty covers and how technical support will work.
Maintenance
Confirm the service schedule, inspection requirements, consumables and estimated recurring costs.
Local support
Identify the service provider, parts arrangements and escalation contact for your destination.
Training & handover
Ask what training is included, who can operate the chamber and how new staff will be trained later.
Availability, lead times, warranty and service coverage are confirmed for each project. Device documentation must match the exact model and intended use.
