The cheaper chambers usually have limited warranties in the small print. Please read the small print. There is probably a reason when you see a chamber selling really cheap unless its a residential chamber.
If a chamber breaks or anything happens that requires fixing and there is no warranty you can be in trouble. I always would find out what is covered and what is not and for how long. Just because there is a warranty doesn't mean everything is covered. Can you say "Limited Warranty"?
14 day return policies. This is the new trend in chamber sales. If you don't like it they will give you a full refund minus the shipping back and forth. If you want to see the quality of a chamber and trying to compare for yourself its sometimes best to try 2 chambers before you pick one. Some people might like one zipper over the other. Some might get a buckle chamber and get frustrated that it takes an extra step to get in the chamber. Another might prefer the straps and buckles rather than massaging to get the zipper zipped up.
The best advice is to read the warranty and return policy, the updated one. Many policies are on the internet from previous years and haven't been updated. Check with us to make sure you are getting the most current warranty or check with the manufacturer of that chamber. Some manufactures offer a full warranty on all components and don't itemize the zippers, windows or seams.
Bulkheads – the entry to your chamber - Keep this in mind so you know about this in about 4 to 6 years.
Wherever a gauge, valve or accessory attaches to the chamber there is a bulkhead. It acts as the secure point to access the inside of the chamber for inflation, venting, adjusting the pressure, medical pass through.
I've found that the design of the bulkhead is what makes the chamber more secure. There are two types of bulkheads: welded types and the mechanical types. If the the bulkhead is not strong enough or they are not strong enough to pass the "aging test" as they call it, not at first but after about 4 to 5 years is when the bulkheads can start failing and leaking. This will prevent the chamber from going to full pressure. I strongly recommend to not use the chamber even if it still is pressurizing but leaking though the bulkhead. Many people don't know it as the sound is covered up by the noise from the release valves and all the sudden people go in one day and wonder why their chamber won't inflate and don't know the reason. They send it in and they bubble test it. When someone says their chamber won't inflate and its about a 4 to 6 year old chamber, this is usually the reason.
Welded bulkheads can be repaired easy. Note: always find out the price of how much it will cost you when you need to replace all the bulkheads at once. I would store that away in a file so you don't overpay when it happens. The mechanical bulkheads are the easiest to repair. They don't have to weld anything. It can be just unscrewed and screw in the new one. It's really that easy and you can use even a pair of pliers at home. The manufacture will usually send you the replacement bulkheads to do this at home.
I've also heard of people who had welded bulkheads fail and ordered a mechanical bulkhead. Most people don't know this can be done and they save about 500 dollars in repair costs.
Note: more expensive chambers usually cost more to fix. I strongly recommend asking up front before you buy a chamber what the repair charge breakdown for the most common things are.
Note: and this is a BIG NOTE…… THIS UPSETS ME OFF MORE THAN ANYTHING.
If you hear “we would have to see it first” or “it will need to be inspected” be very suspicious. Ask any car dealer what it costs to replace the spark plugs and you get a guaranteed quote. Your hyperbaric chamber dealer should give you guaranteed repair quotes.
