Our newest Large Wheelchair Accessible and Walk-In Vertical Hyperbaric Chamber is designed to support rolling a wheelchair directly into the chamber - the most accessible hyperbaric chamber we offer. This vertical chamber stands 6.5 feet tall allowing users to stand inside, and is 71 inches deep so a customer can either relax in a reclining chair or lay down. The wide entry door - 31 inches wide by 57 inches tall - provides effortless access for wheelchair users and those with significant mobility challenges.
This is our most versatile chamber available. Operating at 1.3 ATA with an upgraded 10 LPM - 20 PSI oxygen generator producing 96% purity, redundant pressure regulators, dual pressure gauges, emergency pressure relief button, and a standard dehumidifier - the XLT MC4500 combines unmatched accessibility with professional-grade performance. Built to last 25–30 years with triple heat-welded seams, medical-grade materials, and tested 43,000+ hours at 3× pressure with zero faults.
The XLT MC4500 features a wide entry door measuring 31 inches wide by 57 inches tall - wide enough to roll a standard wheelchair directly into the chamber without transferring to a chair or bed. Standing at 6.5 feet tall with a 63-inch width and 81-inch height (the tallest chamber in the MC range), there is ample room to maneuver inside. This is the only chamber in the range that accommodates a wheelchair user without requiring them to leave their chair.
At 71 inches deep and 81 inches (6.5 feet) tall, the XLT MC4500 accommodates users standing upright, seated in a reclining chair, or lying down on a mattress. This triple-mode flexibility makes it the most versatile chamber in the Oxygen Health Systems range - suitable for individual sessions, supervised clinical sessions, and users who cannot lie flat in a standard horizontal chamber.
The XLT MC4500 is available in two door configurations. The standard door is hinged from the bottom - this is the wheelchair-accessible version, allowing a wheelchair to roll directly in over a flat entry threshold. The U-style door is hinged at the top, making it easier to zip closed - but the raised bottom threshold means it is not suitable for wheelchair access. Choose the standard door if wheelchair access is required; choose the U-style door if you prefer the easier zip-up closure for seated or standing entry.
The XLT MC4500 is built with triple heat-welded seams, medical-grade 44 oz TPU/polyester Dacron materials, and a proprietary 2-zipper system with center flap. Our test systems have been running for over 5 years continuously at 3× the operating pressure - over 43,000 hours with zero faults. The reservoir bag is rated for 39 years at 1 hour per day, 5 days per week. Certified ISO 9001, ISO 14001, and ISO 13485.

The warranty does not cover damage resulting from misuse, overuse, mishandling, unauthorized modification, sheathing change, inadequate maintenance, improper equipment handling, or user operation.
FAQs
Can a wheelchair roll directly into this chamber?
Yes. The XLT MC4500 features a 31-inch wide by 57-inch tall entry door - specifically designed to allow a standard wheelchair to roll directly into the chamber without the user needing to transfer to a chair or bed. This is the only chamber in the Oxygen Health Systems range designed for true wheelchair-roll-in access.
Can I use this chamber by myself without a second person?
Yes. This hyperbaric chamber can be operated alone for home use. All controls are accessible from inside the chamber, and the emergency pressure relief button is located within reach from seated, standing, or lying positions inside the chamber.
Can I stand, sit, or lie down inside this chamber?
Yes - all three. The XLT MC4500 stands 68 inches tall (over 5.5 feet) and is 71 inches deep, providing enough room to stand upright, sit in a reclining chair, or lie down flat. This triple-mode flexibility makes it the most versatile chamber in the Oxygen Health Systems range.
What pressure does this chamber operate at?
The XLT MC4500 operates at 1.3 ATA (4.3 PSI | 32 kPa) standard, with an optional upgrade to 1.4 ATA (5.8 PSI | 42 kPa) with a 10 LPM oxygen generator producing 96% oxygen purity at 20 PSI. This pressure is sufficient to deliver compressed oxygen effectively for hyperbaric therapy sessions.
Why does this compressor have 180 LPM airflow when others have 72–120 LPM?
The XLT MC4500 has a significantly larger interior than standard horizontal lying chambers - 71″L × 63″W × 81″H vs a typical 89″ × 32–40″ cylinder. A 180 LPM compressor is needed to efficiently pressurize and maintain this larger volume at 1.3 or 1.4 ATA, maintain consistent circulatory airflow, and ensure safe CO₂ management throughout every session.
Is air conditioning included?
A 300-watt dehumidifier is included as standard at no additional cost. A full dual-action air conditioning system (550W, 67 lbs) is available as an optional add-on for $2,500 - with a larger capacity unit appropriate for the XLT MC4500's greater interior volume. We are the only hyperbaric manufacturer to offer an air conditioning system designed specifically for hyperbaric oxygen chambers.
What is included in the LED interior lighting system?
A full LED interior lighting system is included as standard. Given the size of the XLT MC4500's vertical interior, the LED lighting ensures full visibility throughout the chamber for users, attendants monitoring through the windows, and for sessions conducted with the door closed.
Who is this chamber best suited for?
The XLT MC4500 is best suited for wheelchair users and individuals with significant mobility limitations; rehabilitation centers and clinics serving mobility-challenged patients; users who need to stand inside a hyperbaric chamber; multi-user clinical environments where flexibility of use mode (stand, sit, lie) is important; and long-term home users who want the most accessible chamber available.
Do you ship to Alaska & Hawaii?

How do oxygen molecules get deeper into your tissues with Hyperbaric Oxygen Therapy?
Under increased pressure, oxygen molecules shrink and can squeeze through constricted blood vessels, inflamed tissue, across the blood-brain barrier, and into lymph nodes, cerebrospinal fluid, and the musculoskeletal system. This is analogous to CO2 dissolving into soda under pressure - when the can is opened, CO2 expands and you see the fizz. The same principle applies to oxygen under hyperbaric pressure: molecules dissolve into the blood plasma and are delivered to oxygen-starved tissues, supporting cellular repair and optimal activity. Oxygen is the final electron acceptor in the Electron Transport Chain where all ATP is produced. Without oxygen we cannot make energy for our brain, organs, or tissue. The more oxygen delivered to our tissues, the healthier, more energetic, and mentally well we feel.
What style of door do I need to put a wheelchair inside the chamber?
The standard door that comes with the XLT MC4500 is designed for wheelchair access - it is hinged from the bottom, providing a flat threshold for a wheelchair to roll over. The upgraded U-style door (hinged at the top) will not work for wheelchair access, as the bottom of the door frame is raised and not flat enough for a wheelchair to pass over. If wheelchair access is your priority, always order the standard door configuration.
Does it need an AC unit if it is used in an air-conditioned facility?
The hyperbaric chamber gets 5-10 degrees warmer inside during sessions. With this model a dehumidifier is included as standard, which may reduce the interior temperature by up to 3 degrees. Typically we do not recommend adding the AC unit if you are already in a room that has its own air conditioning. However if sessions take place in a warm or poorly ventilated space, the optional AC system can make a meaningful difference to comfort. Call us at 251-292-1169 if you are unsure.
What is the difference between the MC4000, MC4400, and MC4500?
The MC4000, MC4400, and MC4500 hyperbaric chambers are all the same design - just different sizes. See the comparison image below for the dimensions of each model side by side.
