What happens after the chamber arrives at your door.

Confirm doorway and corridor widths along the path from delivery point to the room. Soft chambers fold and pack flat for transport; rigid chambers do not. For Cirrus and Vespers, the largest variants measure 90 × 220 cm — plan a clear path.

• Allow 30–45 cm of clearance around the chamber for ventilation and access
• Choose a level floor; a soft underlayment (yoga mat, cotton rug) extends chamber life
• Keep the oxygen concentrator in a well-ventilated area — not in a closet, not against a wall
• Plan for power: a dedicated circuit is ideal; soft chambers draw ~1280 W

The chamber should live in a room that isn't shared with combustion sources or strong fragrance. Oxygen-enriched air at the mask exhaust raises fire risk for materials that would otherwise ignite slowly.

• No candles, lighters, or open-flame heaters in the same room
• Smoke detector in the chamber room
• Class ABC fire extinguisher, accessible
• Avoid hair sprays, aerosols, oil diffusers in close proximity
• Keep the room cool — soft chambers warm during sessions

Before the first session, run the chamber empty at low pressure to check for leaks and seam integrity. Pressurize, hold, listen, soap-test seams if anything seems off. Read the manufacturer's manual before stepping inside.

• Verify all valves, gauges, and the emergency dump are functional
• Confirm the oxygen concentrator delivers ≥ 90% O₂ on a fresh sieve bed
• Familiarize yourself with the emergency depressurization procedure
• Identify a household member as your "tender" — present or within earshot every session

Soft-shell chambers (Quietus, Meridian, Atlas, Solace) operate at 1.3–1.4 ATA using pressurized room air with an external oxygen concentrator. They are lighter, more affordable, easier to install, and considered safer because they do not pressurize pure oxygen. They suit home wellness practice.

Rigid chambers (Vespers, Cirrus) operate at 1.5 ATA or 2.0 ATA and pressurize an integrated oxygen system. They are heavier, more expensive, and reach the pressures most clinical research has used. They suit clinics, studios, and the most considered home.

Soft chambers run on standard household 220 V / 50 Hz at approximately 1280 W — North American customers should plan for a step-up transformer or have us configure the unit for 110 V at order. Rigid chambers ship configurable for 110 V or 220 V; confirm at the time of quote.

The studio accepts T/T (telegraphic transfer / bank wire), Western Union, MoneyGram, Escrow, and PayPal. The full quoted price includes the chamber and DDP shipping; nothing further is owed at customs or on the doorstep.

For a soft chamber: roughly four weeks total — five working days of production plus eighteen to twenty-five days of DDP sea transit. For a rigid chamber: roughly five to six weeks total — one to two weeks of production plus eighteen to twenty-five days of transit. Air freight is available on request and shortens transit to seven to fourteen days for rigid chambers.

No. DDP — Delivered Duty Paid — means the studio handles customs clearance and import duties for you. The quoted price is the landed price.

Inspect the chamber at the moment of delivery. Photograph and video the packaging and the unit before signing the freight receipt. The studio coordinates the freight claim on your behalf — but the documentation must be captured at receipt, or the insurance window may close.

Yes — particularly if you have a history of seizures, lung disease, recent ear or sinus surgery, an implanted device, an active malignancy, are pregnant, or take certain medications (notably bleomycin, doxorubicin, cisplatin, or disulfiram). The safety module of the owner's guide covers this in detail. Echelon does not provide medical advice.
