A hardshell chamber is a rigid pressure vessel — steel with polycarbonate viewing panels — that holds its geometry whether it is pressurised or not. It pressurises quickly, holds pressure precisely, and carries a control and safety suite a flexible shell cannot: dual HD control panels, triple relief valves, HD intercom, and a clean-air suite on the intake. Our models run from 1.3 ATA to 2.5 ATA depending on the model, which is the entire reason this class exists.
It is also a piece of capital equipment that arrives on a truck, and that is the part buyers underestimate. The pressure question is easy. The building question is where hardshell purchases go wrong, so this page is mostly about the building.
Plan this before you sign, not after. In order of how often it causes trouble:
A crated hardshell will not go through a standard interior door, and it will not go up a residential staircase. Measure the full path — truck to final position — including door widths, turn radius at every corner, hallway width, and any threshold or step. The Grand Pavilion of Power can ship as a two-piece modular install specifically for buildings where the assembled vessel cannot get in. Ask about that early; it changes the freight arrangement.
This is freight, not parcel. That means a truck that can reach your address, a lift gate or a dock, and someone on site at the delivery window. Our white-glove delivery covers placement rather than leaving a crate at the kerb, and for anything complicated our professional installation service handles it end to end.
Rigid vessels are heavy and the load is concentrated. Ground floor on slab is the straightforward answer. Anything above ground floor is a question for whoever knows the structure, not a question for us. You also need clearance around the vessel for the door swing and for service access, not just the footprint itself.
Requirements vary by model and by how the oxygen side is configured — the Grand Vessel of Power Pro ships with two concentrators for 20 LPM total, and two concentrators is a different electrical picture than one. Confirm the circuit for your specific configuration before delivery day rather than assuming an existing outlet will carry it.
Then code applies, and the relevant framework is NFPA 99 for the room the chamber sits in. We sell an NFPA 99 compliance kit for exactly this, and we would rather you buy it up front than discover the gap during an inspection. Our ventilation and safety notes in the buyer's guide explain what the standard is asking for in plain terms.
Three single-occupant models, then the multi-person vessel. All include the hardshell control and safety suite and access to our in-house service team.

For a hardshell, the useful first conversation is about your room, not about the chamber. Send us the door widths, the floor, and the pressure you need, and we will tell you which models actually fit before quoting anything.
