FINK FESL-324 (Quad): 4-seat hyperbaric chamber
Four seated places, the largest capacity in the compact FESL range. Medical oxygen by mask at up to 2.0 ATA.

Four seated places for supervised treatment
The FINK FESL-324 (Quad) has the highest seat count in the compact FESL range. It accommodates up to four people in shared sessions at compatible prescribed pressures, with a trained operator present throughout.
Compare that capacity with the courses your clinical team expects to run, the appointment timetable and staffing. Include sessions where fewer places are occupied. A smaller model may be sufficient when demand or compatible appointments are more limited.
Check width, weight and access together
The vessel is 4.29 m wide, 2.3 m deep and 2.2 m high, with a listed weight of 3,300 kg. These figures make the room and structural checks central to model selection. See FINK’s Quad specifications. The final room needs additional working and service space beyond the vessel dimensions.
The chamber is modular, with sections brought through standard doorways for assembly in the room. The actual delivery route must still be checked before ordering. Ask the project team to consider that route together with floor loading and access to the equipment after installation. A room that fits the vessel outline is only the beginning of the plan.
Prepare to operate all four places
Medical oxygen is delivered to each occupant through a personal mask, while the cabin is pressurised with air. Confirm cylinder storage, delivery and reserve arrangements for the intended four-seat schedule. Do not scale a single-seat delivery estimate into a promise for this configuration. FINK’s project proposal should establish the oxygen and supporting equipment requirements.
For a hospital service that needs a different capacity or arrangement, compare the seated line with FINK’s larger multiplace systems, which are built to order and quoted per project. The hospital planning page explains that choice.

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.
