CO2 cartridge in all SECUMAR lifejacket cannot inadvertently unscrew from the inflation device during its intended use. In fact, the SECUMAR inflation devices were designed to precisely avoid this scenario.

Since 1992 all automatically inflatable SECUMAR lifejackets for leisure and professional use incorporate one of the following two SECUMAR inflation devices:

  1. SECUMATIC 3001S (since 1992)
  2. SECUMATIC 4001S (since 1999)

The two inflation device are described in more detail below.

CO₂ spare cartridges with 2 pills and pins

16 g – Mini
20 g – Junior
22 g – Midi, Junior (from 2015)
32 g – 150 N
38 g – KSK 20
43 g – 220 N
56 g – 275 N
60 g – 275 N
75 g – KSK 40

All SECUMAR CO₂ cartridges are 100% weighttested. The extremely pure carbon dioxide gas (99.95% pure) prevents icing up as well as preventing any delay in its expansion during the inflation process. (applicable for all lifejackets with firing mechanisms SECUMATIC 3001 S, SECUMATIC 2000 or SECUMATIC 10).

Yes! Each passenger may carry two lifejackets each with a maximum of two (2) CO₂ cartridges per lifejacket and no more than two spare cartridges in their luggage. Generally, there is no size limit for CO₂ cartridges in lifejackets. These rules are developed by the “Dangerous Goods Panel” of the ICAO, a sub-organization of the UN, and incorporated into the ICAO T.I. released regulations so they are valid worldwide. They are also included in the dangerous goods regulations (DGR) of the IATA. Unfortunately, some airlines incorporate size limits for CO₂ cartridges that may complicate travling with lifejackets.
