Choose VISTA when you want a one- or two-person layout and the route into the room takes the complete 1,400 mm body. Choose LUMEN when doors, corridors or elevators are tight — its side modules come off for a 770 mm central body — or when you want the illuminated door. Inside, they are the same size.

VISTA vs LUMEN
Our 90-second explainer: the bare bodies side by side, a 900 mm door, an apartment elevator, seating and the illuminated door.
One body or three
Look at the bare steel bodies on our factory floor and the difference is obvious. VISTA is one integrated body. LUMEN is modular: a central body plus two removable side modules. Each LUMEN module has a welded flange; the side modules bolt to the central body, and outer metal covers go on last to hide the joints. VISTA cannot be dismantled into side modules — it ships and installs as one piece.
The door test
Take a 900 mm door. VISTA, 1,400 mm wide overall, cannot get through. LUMEN's covers and side modules come off, and the 770 mm central body fits; the modules follow, and the chamber is reassembled inside the room. Apartment elevators work the same way: VISTA will not fit, LUMEN goes up in parts and is rebuilt upstairs.
Two cautions. First, 770 mm and 1,400 mm are body widths, not clear doorway sizes — allow handling clearance, and check height, turns and the full route. Second, always confirm the split sizes, clearances and the elevator's rated load with our engineers before you order; reassembly follows a plan agreed for your project.
| VISTA | LUMEN | |
|---|---|---|
| Seating layout | 1 or 2 people | 1 person |
| Doorway access | Complete chamber body | Removable side modules |
| Body disassembly for access | Not available | Left and right modules can be removed |
| Reference access width | 1,400 mm overall | 770 mm central body after module removal |
| Illuminated door | Not offered | Optional |
| Plain / illuminated step | Both optional | Both optional |
| Exterior design | Rounded or Defined contour | Modular flagship form |
| Approx. chamber weight | 860 kg | 1,000 kg |
| External size | 1,850 × 1,400 × 2,000 mm | 1,850 × 1,400 × 2,000 mm |
What is the same
Inside, they are the same size — same width, same interior. LUMEN's metal covers only make it slightly longer and taller on the outside. Both operate at 2.0 ATA and share the same standard package: the 10L all-in-one main unit (oxygen concentrator, air compressor and air conditioning; 93% ± 3% oxygen at the concentrator supply), standard interior and sofa, warm-white cabin LED, two touch control panels and two intercoms (one of each inside and outside).
Both can take the same options too: 20L all-in-one + BIBS, single, dual or three-panel infrared, PEMF, folding table, pulse oximeter, negative-ion unit and a plain or illuminated entry step. Three-panel infrared is offered on these two models only.
Seating and the door glow
VISTA offers a single-person layout or a two-person sofa, with NAPA massage seating as an upgrade. LUMEN is designed for one occupant; its flagship NAPA sofa with folding desk is the recommended upgrade to the included standard sofa.
LUMEN also offers an optional illuminated door, lit from the gap between its metal cover and the body. VISTA does not offer this. Illuminated entry steps are optional on both.
Which to choose
- Need two-person seating, and your route fits 1,400 mm? VISTA.
- Tight doors or elevators, or you want the illuminated door? LUMEN.
- Weight matters? VISTA is about 860 kg against LUMEN's 1,000 kg, excluding the main unit.
Send us your route — the narrowest door, any stairs and lifts — and we will help you choose.
Questions
Are VISTA and LUMEN the same size?
Yes — both are 1,850 × 1,400 × 2,000 mm externally with the same interior. LUMEN's metal covers make it slightly longer and taller outside, but the documented dimensions are the same.
Can VISTA be taken apart to get through a door?
No. VISTA is one integrated body; plan the route for the complete 1,400 mm chamber. LUMEN's side modules remove for a 770 mm central body.
Is the illuminated door available on VISTA?
No. The illuminated door is offered on LUMEN and ORION. Plain or illuminated entry steps are optional on VISTA and LUMEN.
