Macy Pan vs OxyRevo: Home Hyperbaric Chamber Brands Compared (2026)

Macy Pan vs OxyRevo: which home hyperbaric chamber brand is the better fit? Their spec sheets look alike at first glance, so it is easy to feel stuck. Both make soft and hard chambers, both reach 2.0 ATA, and their prices overlap. This guide puts the facts side by side so you can see where they really differ.

At Selected Comfort, we help families and clinics choose home hyperbaric chambers every week. We carry both brands in our hyperbaric chamber collection, so we have no reason to push one over the other. Every spec below comes from the brands' own listings and websites. Where a brand does not publish a detail, we say "Not published."

Macy Pan and OxyRevo at a glance

Both are Chinese manufacturers. Macy Pan is based in Shanghai and says it has made chambers for 17 years. OxyRevo is based in Hangzhou.

The biggest difference is scope. Macy Pan sells almost every chamber shape, including hard chambers for up to five people. OxyRevo keeps a smaller line with shared design features: curved zippers, dual gauges and a one-press pressure selector.

Model range: who makes what

Macy Pan has more models and more chamber types. OxyRevo has fewer models that share one design.

Pressure options (ATA)

Both brands cover the same pressure bands: about 1.3 to 1.5 ATA for soft chambers and up to 2.0 ATA for hard chambers. The difference is in how you pick a setting.

ATA means "atmospheres absolute." 1.0 ATA is normal sea-level air pressure, so 2.0 ATA is double. Our guide on 1.5 ATA vs 2.0 ATA chambers explains this in more depth.

• Macy Pan soft: ST801, ST1700 and L1 go up to 1.5 ATA. ST901, ST2200 and MC4000 top out at 1.4 ATA.
• Macy Pan hard: HP1501 is 1.5/1.6 ATA. HP2202, Dia90 and HE5000 models reach 2.0 ATA.
• OxyRevo soft: a pressure selector lets you set 1.2, 1.3 or 1.4 ATA with one press (up to 1.5 ATA on the Apex and Forward90 1.5 models).
• OxyRevo hard: Quest and Space60 come in 1.5/1.6 ATA or 2.0 ATA builds. The pressure switch valve lists 1.3, 1.5, 1.8 and 2.0 ATA settings.

Soft vs hard shell from each brand

Soft chambers from both brands are the lower-cost, portable choice. Hard chambers cost more and can reach 2.0 ATA. For the general trade-offs, see our full soft vs hard shell guide.

Soft shell. Macy Pan soft chambers are light. The ST801 and the L1 each weigh 15 kg, before the compressor and concentrator. Macy Pan lists an internal pressure gauge so you can read the pressure from inside. OxyRevo soft chambers use a curved zipper design, seams joined by heat welding instead of glue or stitching, and two pressure gauges, one inside and one outside.

Hard shell. Both brands build hard chambers from stainless steel with polycarbonate (clear plastic) windows or doors. OxyRevo's Quest and Space60, and Macy Pan's HP1501 and Dia90, list control panels inside and out, a power-failure system that releases pressure on its own, a door sensor and air cooling. Macy Pan's HP2202 weighs 150 to 200 kg and the HE5000 FORT 380 kg. OxyRevo hard chamber weights are not published in our listings.
