CEJN / Series 345
Vendor: CEJN
Coupling Type: Quick Disconnects
Description:
35 bar (508 PSI) – 1100 l/min (39 CFM)
Coupling Category:
Quick Connect Couplings for Breathing Air Applications
Series 345 is a double shut-off series with both a valved
coupling and nipple. The specially designed valve provides
an extremely high rate of airflow. This series is well-suited for breathing air diving applications and for applications that demand a closed system when disconnected, such as surface air diving. Like most other CEJN breathing aircouplings, Series 345 offers one-hand-operated connection, an integrated safety feature that guards against unintentional disconnection, a grip-friendly locking sleeve, and a broad connection range.
