  • 4500 psi or 2216 psi

    Our small department is buying 10 new air-packs and extra bottles. We are trying to determine if we should buy Scott 2216 psi with 30 minute bottles, or Scott 4500 psi with 45 minute bottles. I'm looking for any feedback that you may have. Thanks.

    Our department uses the Scott 2216 bottles. I personally wish that we had the 4500 (45 minutes).

    Also, we use the heavy steel bottles. If we had to choose again, I would ask for the composite bottles. These are so much lighter.

      We do not use scotts, we use interspiro's with 4500 and 45 minutes. We had tested the scotts and we liked them also, but the powers that be decided to go the other way. With the light weight units now days it is nice to have the high pressure and more time to work in the enviroment. We won't go back to the 2216 for that reason, and that reason alone.

        We are also getting new SCBAs. I am pretty sure we are going with Drager 4500psi 60 minute wrap bottles.

        Not cheap, but they should last a long time. Lifetime waranty on many parts.

        We want the 60 minute bottles because we are a small department that has to make the most of our initial "sprint" at a fire. We often dont have enough personel for a switch off at 20 or 30 minutes, we need to stick to it, and if we can get it done on a 60 minute cylender, then we should have the mutual aid there by then.

          I myself love the 4500 45 min bottles, however that being said you have to look at a few things. The first being a fill station, do you have the capability to fill the 4500 psi bottles? Also you have to adjust your rehab time, in my dept after one bottle you go straight to rehab and stay unless its really bad and there is no choice due to a lack of manpower. You just have to really take a hard look at your depts capabilities, before you make the decisions.

            4500 30 minute scotts. Low profile, light in weight. We decided against the 45 or 60 minute packs because of the larger size. The 45's were in contention, but we really don't want our firefighters inside for that long. a 30 minute cylinder should supply a solid 20 minutes, after that, its time to reevaluate the situation.

              We use the 4500 (30 min) bottles for firefighting. Haz-Mat uses the 4500 (60 min) bottles, so that they have time to de-con and get out of thier suits while still on air.

                Our Department uses a few different kind of airpacks all of our new ones are 2216 MSA bottles, All of the other ones are the old ones. The MSA ones are wrapped very light, there all in our initial trucks, all the old ones are in like our other apparatus that wouldnt see a structure much where you may need to go in like our tanker.

                  The problem with carbon wrapped cylinders is that they are damaged by abrasion much, much easier. One scrape down to the carbon layer and they are condemned. It doesn't take much, dragging out a downed firefighter during a drill will do it. Remember, 80% of the strength of the cylinder is in the carbon fiber wrap (the aluminum inner shell is the other 20%. Also, the cylinders only have a life of 15 years with pressure testing every 5 years.

                    We started switching from 2216 to 4500/45min bottles in the mid-90's. It was in response to a house fire in which 3 FF's ran out of air searching for a child. They did make the save, but all went to the hospital for smoke inhalation. After that we decided we needed longer lasting bottles and decided to go with 45 minute bottles.

                      More info

                      We currently have 8 Scott 2.2 models. We like them a lot, but they have steel bottles and are very heavy. We are leaning toward 2216 psi so that the rest of our bottles will be compatable with the new packs. If we go to 4500 psi, only the new bottles can be used. I'd personally like to go to a 45 minute bottle for that little extra time inside, but is this really needed? Does the extra time outweigh the interoperability with our other packs?

                          Using the MSA Extreeme SCBA since 1998 we steadily changed over the whole department over since about 2001. They are carbon fiber bottles and they are so much lighter than the old steel ones, us old people can appreciate them ALOT more than our new ones.Thye are rated at 30 minutes and seem to work well for us, they replaced ol Scott 2.2's from the 1970's era.

                            Another advantage of high pressure packs is the smaller bottle size which makes for a reduced profile.
