Most medical device companies do not talk about who manufactures their products. The manufacturing story is considered operational detail — interesting to engineers, irrelevant to buyers. RxAir360 takes the opposite view. Who manufactures the RxAir360 chamber is not a footnote. It is a core part of the value proposition — and it is a story that no competitor in the hyperbaric market can tell.
The RxAir360 monoplace hyperbaric chamber is manufactured by Electroimpact — the precision aerospace engineering company that builds the automated assembly systems used to manufacture Boeing and Airbus commercial aircraft. When you understand what that means in terms of engineering tolerance, quality systems, and manufacturing precision, the significance becomes clear.
This post tells that story — what Electroimpact builds, why aerospace manufacturing standards matter for a medical device, what the RxAir360 chamber is made of and how it is built, and what the patent protection around its design means for the company's market position.
Walk into any hospital hyperbaric program in the United States and you will see the same basic design that has existed since the 1960s: a horizontal steel tube, roughly the diameter of a submarine torpedo tube, with an acrylic viewport and a sliding door. The patient lies flat inside. The chamber pressurizes. Sixty minutes later, it depressurizes and the patient exits.
This design has remained largely unchanged for six decades. The manufacturers that serve the hospital market built their operations around this established form factor, and the engineering focus has been on refinement within the horizontal model rather than exploring alternative orientations.
The limitations of this design for physician-office deployment are significant. Horizontal chambers require substantial floor space — a room of 300 to 500 square feet minimum. They require the chamber door to open fully, adding additional clearance requirements. For the 500,000 physician practices in the United States that do not have a dedicated hyperbaric suite, the horizontal design is simply not viable.
RxAir360 started from a different question: what does a hyperbaric chamber need to look like if the requirement is that it fits in a standard physician exam room? The answer required a fundamentally different approach to both engineering and manufacturing. It required a partner capable of precision engineering at a level the medical device industry rarely accesses.
Electroimpact is not a contract manufacturer. It is one of the world's leading precision aerospace engineering companies — specializing in the automated assembly systems that make commercial aircraft production possible at scale.
To understand what that means, consider what commercial aircraft manufacturing requires. A Boeing 787 Dreamliner contains approximately 2.3 million individual parts. The fasteners that hold the fuselage panels together must be installed at tolerances measured in thousandths of an inch — consistently, across thousands of assembly operations per aircraft. The engineering systems that make this possible are what Electroimpact designs and builds.
The precision standards Electroimpact operates to are not approximate guidelines — they are mathematical requirements enforced by quality systems that would be foreign to most manufacturing environments.
Applying those standards to a pressurized medical device changes what the word quality means. When a chamber is designed to hold human beings at three times atmospheric pressure — when a structural failure means a catastrophic event — the manufacturing precision behind it matters in ways that exceed any marketing claim.
A monoplace hyperbaric chamber pressurizes to 3 ATA — three times normal atmospheric pressure. Every weld, every seal, every structural joint must maintain integrity under that pressure, treatment after treatment, year after year. The consequence of a structural failure is not a product defect — it is a safety event involving a human being inside the chamber. Electroimpact brings those standards to the RxAir360 chamber.
The RxAir360 monoplace hyperbaric chamber is built around a vertical, seated-upright orientation — the fundamental design departure from the legacy horizontal model that makes physician-office deployment possible.
The chamber shell is constructed from steel — chosen for its strength-to-weight ratio, pressure vessel performance, and compatibility with the precision welding and fabrication processes Electroimpact employs. The chamber incorporates four acrylic viewports — the same material used in commercial hyperbaric chambers for decades — providing the patient with a broad outward field of view during treatment. Steel and acrylic form the same material combination used in FDA-cleared hyperbaric systems.
The decision to orient the chamber vertically — with the patient seated upright rather than lying horizontal — is the engineering decision that unlocks physician-office deployment. A seated upright patient requires a much smaller footprint. The chamber door opens to the front rather than the end, eliminating the extended clearance requirement of horizontal designs.
The vertical orientation may offer secondary patient-experience considerations — including a seated position for longer sessions and the ability to enter and exit the chamber standing rather than climbing in and out of a horizontal tube. The primary design driver was footprint. The vertical design is what makes a standard exam room (approximately 100–120 sq ft) a viable deployment space.

In medical device markets, intellectual property helps protect engineering investment during the development and regulatory phases. A company that invests years solving an engineering challenge can use patent protection to secure its development timeline while navigating the FDA clearance process.
RxAir360 holds an issued U.S. patent covering the vertical monoplace hyperbaric oxygen therapy system designed for standard physician exam rooms. This protection covers:
The issued patent provides RxAir360 with a defined period of intellectual property protection — in place prior to FDA clearance and commercial launch. This allows the company to focus on the regulatory pathway and manufacturing readiness with its design position secured.
The combination of patent protection and Electroimpact manufacturing capability represents significant development infrastructure for a pre-revenue medical device company. Replicating the same engineering approach would require navigating the existing patent landscape and establishing manufacturing partnerships capable of precision pressure vessel fabrication — both of which involve substantial time and capital commitments.
The RxAir360 chamber is designed in alignment with the three primary safety frameworks governing clinical hyperbaric equipment.
Pressure Vessels for Human Occupancy
Construction, materials, welding, testing, and inspection of chambers pressurized with humans inside. Sets the engineering baseline for structural integrity at clinical operating pressures.
National Fire Protection Association Healthcare Facilities Standard
Governing oxygen-enriched environment safety, electrical systems, and emergency procedures. Defines the safety systems that prevent fire and explosion hazards in clinical HBOT settings.
Medical Electrical Equipment Standard
Covering electrical safety, electromagnetic compatibility, and protection against hazards for devices used in clinical settings.
Meeting these standards is not a marketing claim — it is a design and manufacturing requirement enforced through independent testing and FDA review. Electroimpact's quality systems provide the manufacturing precision and documentation infrastructure that compliance requires.
Most hyperbaric chamber manufacturing draws from traditional medical device fabrication. RxAir360's partnership with an aerospace precision engineering firm represents a different approach — one that brings aviation-grade quality standards to pressure vessel construction.
Electroimpact operates quality management systems designed for aviation — a field where documentation, traceability, and verification requirements are rigorous. These systems complement the quality framework required for medical device manufacturing.
Electroimpact's capabilities provide production infrastructure to scale from development to commercial volume as demand grows — an important consideration for any device transitioning from regulatory clearance to market deployment.
The Electroimpact relationship provides a tangible reference point for evaluating manufacturing quality. Boeing and Airbus rely on Electroimpact for critical aerospace components — the same precision engineering approach is applied to the RxAir360 chamber.
