CEJN / Series 344
Description:
35 bar (508 PSI) – 1950 l/min (69 CFM)
Coupling Category
Quick Connect Couplings for Breathing Air Applications
Manufacturer
CEJN
Series 344 is specially designed for applications with
low-weight requirements. The shorter design of the coupling
gives it a significantly lower weight than other couplings
with the same performance. Series 344 is recommended
primarily for breathing air firefighting applications, but is
also well suited for diving equipment. Its specially designed
valve provides an extremely high rate of airflow. Like most
other CEJN breathing air couplings, this series offers onehand-operated connection, an integrated safety feature that guards against unintentional disconnection, a grip-friendly locking sleeve, and a broad connection range.
