Whether two people can enter the same cabin together can’t just look at the “double” in the product name “. Some widened cabins are aimed at 1 adults and 1 children, some allow two people to sit at the same time, and some multi-person hardware cabins provide two-seat, 3-seat, bed board or bench layouts. They are not the same solution in terms of posture, entry, pressure and installation conditions.

First Confirm Who “Two People” Specifically Refers To
Explain to the supplier whether the two users are two adults, or 1 adult and 1 child, and confirm whether they can maintain the position specified for the product at the same time. ST901 is a widened soft horizontal cabin. The adaptation method given in the data is that 1 adults and 1 children lie together. ST2200 is also facing 1 adults and 1 children, but in sitting or leaning back posture. They cannot be interpreted as suitable for two adults just because they are “wider in space.
The MC4000 N/U is a two-seat soft cabin. Its rated number of people, sitting position and entrance form are closer to the two-person hyperbaric chamber these 1 purchase requirements. Another option is a multi-person hardware cabin: HE5000 can be equipped with two-seat, 3-seat, bed board or bench, but the specific internal layout should still be clearly written when quoting, and the series name cannot be regarded as a two-seat configuration certificate.
Try to Get in and Out First, Then Compare Appearance
If two people can sit down, it does not mean that they can enter and leave smoothly. MC4000 N/U adopts U-shaped or N-shaped zipper structure with enlarged entrance, which can be used for wheelchair entry. The overall dimensions of the cabin are 140cm long, 130cm wide and 175cm high. If one of them uses a wheelchair, check the clear width of the entrance, threshold, ramp, cabin fixing, wheelchair material compatibility and rated load before purchasing. Product photos can only show the general space, can not replace these dimensions and restrictions.
The hardware compartment also depends on the opening direction of the door, the net size of the entrance, the internal turning space and the emergency evacuation conditions. The overall dimensions of the HE5000 are 2070mm long, 1616mm wide, and 1749mm high. The catalog provides a variety of internal layouts; the HE5000 Fort uses face-to-face multi-person seats. Don’t just ask “double”, ask the supplier to indicate the number of seats, seat orientation, available interior space and the corresponding complete model on the configuration list.
Pressure Is Not an Additional Label for Capacity
The pressure specification of MC4000 N/U is 1.3 ATA or 1.4 ATA, and the pressure specification listed in HE5000 series data is 2.0 ATA. A higher number does not automatically indicate that the product is more suitable for two people, nor can it alone prove use, effectiveness or safety. When comparing, the pressure caliber should be unified, and the normal working pressure, maximum allowable working pressure and pressure relief setting pressure should be checked at the same time.
Also put pressure and structure, intended use, oxygen supply mode, operating instructions and professional supervision requirements together. If the supplier uses atm or psi, it shall be required to indicate whether it represents absolute pressure or gauge pressure. Information containing psi also distinguishes psia from psig. Numbers with different calibers are placed in the same quotation sheet. They look comparable, but in fact they may not be the same thing.
Verify the Site Against the Entire System
The folding of the software compartment does not mean that the compressor, oxygen supply or oxygen generation equipment, cooling equipment and accessories can be ignored. The MC4000 N/U cabin data is marked with a weight of 18kg, but the packaging size, component weight, number of carriers and required time shall be confirmed according to the whole system for handling and installation.
Hardware-based multiplayer pods have more straightforward venue requirements. HE5000 data label weight 650kg. Before purchase, measure the transportation channel, door width and turning space, and confirm the ground bearing, room clearance, power supply, grounding, ventilation, fire protection and maintenance space. The equipment can pass through the door, which only means that it can be transported in, and does not mean that the installation location meets the operating and maintenance conditions.
Match Quotes with Verifiable Configurations
At a minimum, the 1 comparable quotation shall indicate the manufacturer, complete model, number of rated personnel, internal layout, pressure caliber, cabin material, oxygen supply configuration, installation conditions and service scope. It should also be confirmed which instructions define the communication, emergency pressure relief, cleaning, maintenance, inspection and external monitoring requirements. If the equipment is used in a specific market or medical scenario, the relevant licenses, intended use and operating conditions should also be implemented to specific models, and cannot be replaced by enterprise-level publicity or similar models.
Finally, I return to the actual actions of the two users: whether they can enter, sit firmly or lie down according to the prescribed posture, and whether they can communicate and evacuate quickly in case of abnormality. If these problems do not have the corresponding size, configuration and written instructions, do not use the word “double” to make a decision.
