CEJN Breathing Air couplings have integrated safety features to protect against unintentional disconnection and require only minimal force to connect. The couplings are commonly used for self-contained breathing apparatus (SCBA) and compressed airline breathing apparatus. With the vital function of supplying breathing air, the need for safety and reliability is of high importance. CEJN’s products are designed and manufactured to exacting standards, which has resulted in years of trouble-free service. Presented here are CEJN’s couplings specifically for breathing air applications.
