One seated place for supervised treatment
The FINK FESL-310 (Solo) gives one person a seated place in a hard-sided chamber. A physician prescribes the treatment and a trained operator runs each session, including at home.
For a clinic, one seat means one patient per appointment. Map the proposed treatment courses against the timetable before choosing capacity. For a home installation, confirm that the user and operator can both attend the prescribed sessions.
What the oxygen routine involves
For the single-seat configuration, a six-cylinder manifold lasts roughly eight to nine days at three sessions a week, or about five days at five sessions a week. These are replenishment estimates for planning deliveries, not a recommendation about treatment frequency. The physician prescribes the course.
The manifold changes between cylinders automatically. That feature does not remove the need to arrange fresh medical oxygen and a reserve supply. Before buying, ask who supplies the cylinders, who changes them and how deliveries fit around the planned sessions. See the medical oxygen guide.
Measure the installation, not just the vessel
The vessel measures 2.0 × 2.3 × 2.2 m and weighs 1,300 kg, according to FINK’s Solo specifications. Those dimensions do not describe a finished treatment room. Leave the working and service space to be agreed in the installation plan, and have the floor loading and delivery route checked before selecting a room.
Agree the room layout and access with the installation team before ordering. Include the supporting equipment and medical oxygen arrangements in the written project scope.

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.
Plan the room and oxygen supply
The installation plan needs suitable ventilation and space for the operator, supporting equipment and servicing. Modular sections are assembled in the room, with the actual delivery route checked before ordering.
The cabin is pressurised with air. Medical oxygen reaches each person through a separate mask, supplied by a cylinder manifold with automatic changeover. A trained operator runs every session. The occupant does not self-operate.
Is this FESL model FDA cleared?
Yes. 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.
What does the project 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.
