ARC questions.
More answers in the buyer guides and the FAQ.
How narrow a door can ARC pass through?
ARC is 980 mm wide with its side glass fitted and 860 mm with both side glass panels removed, or 860 mm as built in the flat PC window version. These are body widths, not clearances — send us the route and our engineers check it.
Can ARC have three-panel infrared or an illuminated door?
No. Neither is offered for ARC. Single or dual (head and foot) infrared, seating upgrades, folding table, PEMF and entry steps are optional.
Which features in the photos are standard?
Standard: the 10L all-in-one main unit with air conditioning, standard sofa and wall finish, warm-white interior LED, two touch panels and two intercoms. Lighting colours, NAPA seating, infrared panels, PEMF, 20L + BIBS and the entry step are optional.
What power supply does ARC need?
With the standard 10L all-in-one system: 2,000 W, 20 A at 110 V / 60 Hz, or 1,500 W, 8 A at 220 V / 50 Hz. With the optional 20L system and BIBS: 2,700 W, 25 A at 110 V, or 2,500 W, 13 A at 220 V. A local electrician plans a dedicated circuit. Electrical guide.
What does “93% ± 3%” oxygen mean?
It is the oxygen concentration at the concentrator supply. It is not the oxygen level of the air inside the pressurized chamber, and it is not a medical claim. Oxygen systems explained.
Is there a price list for ARC?
No. Each chamber is configured and shipped to a specific destination, so quotations are prepared per project and confirmed by our sales team.
Can I order ARC in my own colour or with my logo?
Black, white, dark grey and light grey are the standard shell colours; any of the 216 RAL Classic colours can be ordered, and two-tone designs on request. Your own logo is confirmed with your order; private-label (OEM / ODM) projects are welcome, including single units. See the colours, walls and seats.
What warranty and support come with ARC?
SkelundTech's company warranty policy is two years; scope, conditions and start date are set in your contract. Support is remote from the factory team — assembly drawings, guidance and after-sales help — and replacement parts are supplied free of charge; if you need them fast, you pay only the express freight. There are no local technicians at present.
