Macy-Pan ST901: Largest Soft-Lying Chamber in the Macy-Pan Soft-Shell Lineup
Spacious 90" × 36" soft-lying chamber at 1.3–1.4 ATA. Wide enough to fit one adult plus a child, or for a single user to fully recline during extended sessions. Built for families, recovery-focused clinics, and buyers who find standard 32" chambers too tight.
Authorized Macy-Pan Dealer — factory warranty honored, US-side consultation before and after purchase, financing available through Affirm and Brickhouse Capital.
BEST FOR:
- Families wanting room for one adult + one child in the same session
- Taller or larger adults who find 32" chambers too narrow
- Home users running long 90–120 minute recovery protocols
- Medspas and recovery clinics adding a spacious soft-shell HBOT option
- Biohackers stacking HBOT with extended screen, reading, or meditation time
NOT IDEAL FOR:
- Buyers requiring FDA clearance for insurance or clinical billing
- Protocols above 1.4 ATA — step up to ST801 (1.5 ATA) or HP1501 hard-shell
- Small rooms without 100" × 40" footprint clearance
- Anyone unable to equalize ear pressure
- Multi-occupant adult protocols — 36" fits one adult + one child, not two adults
WHY RECOVATHLETE CARRIES THIS
The ST901 solves one problem Macy-Pan's other soft-shells don't: room. Standard 32" chambers (ST801) feel tight for taller adults, larger builds, or parents who want a child alongside them during recovery. The ST901's 36" diameter opens that up. We carry six hyperbaric brands, so our consultation is brand-agnostic — if 1.5 ATA adjustable matters more than chamber width, we'll point you at ST801 or OxyRevo Apex36. If FDA clearance matters more than pressure range, we'll route you to Newtowne. Direct engineering support line, white-glove setup guidance, and financing through Affirm or Brickhouse.
Macy-Pan ST901 | 1.3 to 1.5 ATA Soft-Lying Hyperbaric Chamber
Space without compromise. Room for one adult plus a child, or full reclining for extended sessions.
The Macy-Pan ST901 is the largest soft-shell lying chamber in the Macy-Pan lineup, a full 88 in x 35 in x 35 in interior running 1.3 ATA standard, upgradeable to 1.5 ATA. The 35 inch diameter gives room for one adult plus a child side by side, or a single adult to fully recline during 90 to 120 minute sessions without feeling confined.
Triple-layer TPU with nylon coating, SGS and RoHS certified. Heat-welded seams with no adhesives. Dual YKK zipper sealing. The oxygen concentrator delivers up to 95% purity at adjustable flow rates.
This is wellness and recovery equipment. The ST901 is not FDA-cleared for medical use in the United States. It is used off-label for athletic recovery, sleep quality, inflammation management, and daily HBOT protocols under physician guidance.
Authorized Macy-Pan dealer. Full manufacturer warranty and direct supplier support on every chamber.
Who Buys the ST901
- Families who want one adult and a child in the same session, for parent-child recovery, sleep, or wellness protocols.
- Larger or taller adults who find 32 inch chambers like the ST801 too narrow for comfortable 90-minute sessions.
- Home users running extended 90 to 120 minute protocols where chamber room matters as much as pressure.
- Medspas and recovery clinics offering a premium soft-shell option that positions above entry-tier chambers.
- Biohackers stacking HBOT with reading, meditation, or content during long sessions.
How to Use the ST901
- Enter through the smooth-curved entry with dual YKK zippers.
- Recline on the internal mattress or optional memory foam upgrade.
- Close both zippers fully and confirm the deflate valve is sealed.
- Power on the compressor and oxygen concentrator.
- Adjust working pressure (1.3 ATA standard, 1.5 ATA upgrade) using the pressure converter.
- Relax through your 60 to 120 minute session.
- Monitor pressure via the dual internal and external gauges.
- After the session, depressurize slowly using the release valve.
- Exit once pressure reaches normal level.
Protocol: 3 to 5 sessions per week at 60 to 90 minutes. Start at 1.3 ATA for the first 2 weeks before stepping up to 1.5 ATA.

Also Consider
If you want the same 1.3 to 1.5 ATA range in a smaller, lighter footprint, look at the Macy-Pan ST801 at 32 inches. For a direct cross-shop against a 36 inch soft-shell with in-session adjustable pressure, compare the OxyRevo Apex36. For hard-shell durability and 1.5 to 1.8 ATA pressure, step up to the Macy-Pan HP1501. If FDA 510(k) clearance is required, the Newtowne C4-40 is the largest FDA-cleared soft-shell alternative.

Macy-Pan ST901 FAQ
What is the ST901 and who is it built for?
The ST901 is Macy-Pan's largest soft-shell lying chamber, 88 in x 35 in x 35 in at 1.3 to 1.5 ATA. It fits families who want a parent-plus-child configuration, larger or taller adults who find 32 inch chambers too tight, and home users running long recovery protocols. The 35 inch diameter gives meaningful extra room compared to the ST801's 32 inch.
Can two adults use the ST901 together?
No. At 35 inch diameter, the ST901 fits one adult plus one child comfortably, or a single adult with full reclining room. Two adults side by side requires a larger chamber. If that is your use case, look at the 40 inch hard-shell HP1501-100, the only Macy-Pan chamber wide enough for two adults.
1.3 vs 1.5 ATA, what is the practical difference?
At 1.3 ATA you are breathing oxygen at roughly 30% greater pressure than sea level, appropriate for sleep, general wellness, and mild recovery. At 1.5 ATA the pressure delivers more dissolved oxygen per session for deeper tissue saturation, suited to athletic recovery and inflammation protocols. Most users start at 1.3 ATA and step up to 1.5 ATA as they acclimate. Pressure tier is selected at checkout.
Is the ST901 FDA-cleared?
No. The ST901 is CE-certified, ISO 13485-compliant, ISO 9001-compliant, and SGS-tested, but it is not FDA-cleared for medical use in the United States. It is sold for wellness, research, and recovery use. If you require FDA-cleared equipment for clinical documentation or insurance reimbursement, consider the Newtowne C4-40, the largest FDA-cleared soft-shell alternative. Consult your physician before starting any HBOT protocol.
How should I choose between the ST901 and the ST801?
Both adjust from 1.3 to 1.5 ATA and both are soft-shell Macy-Pan chambers, so choose on size. Pick the ST901 if room matters most: extra interior space, a parent-plus-child configuration, or you are a larger or taller adult. Pick the ST801 if footprint matters most: it is narrower at 32 inches and lighter, better for tight spaces.
Can children safely use the ST901?
HBOT for children should only be done under physician supervision. The ST901's 35 inch diameter allows a parent and child to session together, which many families use for age-appropriate wellness protocols. Ear equalization is a key concern. Children need to be old enough to understand and perform the Valsalva maneuver. Consult a pediatrician before starting any HBOT protocol for a minor.
How long is a typical session and how often should I use it?
Most protocols run 60 to 90 minutes, 3 to 5 times per week. Beginners typically start at 45 minutes at 1.3 ATA for the first 2 weeks before lengthening sessions or moving to 1.5 ATA. Your physician should guide protocol design based on your goals.
Can I operate the ST901 alone?
Yes. The chamber is designed for self-operation. Setup takes 30 to 45 minutes the first time and 10 to 15 minutes after. Dual internal and external pressure gauges let you monitor sessions solo. Most home users are running sessions without an attendant within the first week.
What will I feel during a session?
You will hear steady airflow and feel gradual ear pressure during pressurization, similar to an aircraft takeoff. Some users feel slight fatigue or lightheadedness for 10 to 15 minutes after their first few sessions. This typically resolves as the body adapts over the first 2 weeks of use.
Is claustrophobia a concern in the ST901?
Less than in smaller chambers. The 35 inch diameter and multiple transparent windows bring in natural light and reduce the confined feeling that drives most soft-shell dropout. First-time users typically acclimate within 2 to 3 sessions. If severe claustrophobia is a known issue, request a video walkthrough before buying.
What are the room and power requirements?
You need a minimum 100 in x 40 in footprint for the chamber plus 24 in clearance on the entry side. The operating unit adds another 30 in x 18 in footprint and should sit within 6 feet. Power is 110 to 120V, 60Hz, 15A dedicated circuit. The chamber runs quietly enough (50 dB or lower) to use in a home office or shared room.
Is maintenance complicated?
No. Primary maintenance is replacing the air filter every 6 to 12 months depending on usage. Step-by-step video guides and PDF manuals are linked in the specifications section. Component lifespan: chamber structure 8,000+ hours, compressor 10,000+ hours, oxygen concentrator 5,000+ hours. Detailed service guidance lives in the Shipping & Warranty tab.

Macy-Pan Certifications and FDA Status
Here is exactly how Macy-Pan chambers meet safety standards, what their FDA status means, and where wellness use ends and medical use begins. This applies to every Macy-Pan chamber RecovAthlete sells.
Certifications
| Cert | What it covers |
|---|---|
| ISO 13485 | Quality control and traceability for medical-device manufacturing. |
| ISO 9001 | International quality-management standard for consistent build quality. |
| CE | Meets EU health, safety, and environmental requirements. |
| EC PED | Pressure Equipment Directive. Confirms pressure-vessel safety. |
| SGS | Independent third-party testing of materials and workmanship. |
| ASME BPVC (pending) | North American pressure-vessel code. Macy-Pan is in the final phase of certification. |
These certifications support lawful import and sale across many international markets, backed by 15+ years of Macy-Pan engineering in 123 countries.
What FDA Status Means
Recovery products fall into three FDA categories. Which one applies matters if you bill insurance, document clinical use, or just want clarity.
| Status | What it means |
|---|---|
| FDA-Cleared | Reviewed and authorized for specific medical uses (510(k) or PMA). |
| FDA-Registered | A filing, not an approval. The FDA was notified the product exists. It is not an endorsement. |
| Non-Approved | Not reviewed or cleared by the FDA for any medical purpose. |
Important
Macy-Pan chambers are not FDA-cleared for medical use in the United States. They are for general wellness, recovery, and athletic use. If you need 510(k) clearance for clinical billing, insurance, or institutional purchase, ask us about our US-made, FDA-cleared options.
Off-Label Use
- The FDA clears soft-shell chambers up to 1.3 ATA only for altitude sickness.
- Using a soft-shell chamber for recovery, sleep, or wellness is off-label. Legal, but not FDA-evaluated for those uses.
- Hard-shell chambers at 1.4 to 2.0 ATA are Class II medical devices and need a prescription and PVHO-1 compliance for medical use.
Most Macy-Pan buyers use their chambers for training recovery, sleep, inflammation, and daily wellness, off-label but widely practiced with physician guidance.
