CEJN / Series 346
Vendor: CEJN
Coupling Type: Quick Disconnects
Description:
35 bar (508 PSI) – 800 l/min (28 CFM)
Coupling Category:
Quick Connect Couplings for Breathing Air Applications
The AISI 303 stainless steel construction of Series 346
makes it an ideal choice for applications in tough environments.
Series 346 are also available in acid-proof stainless steel
(AISI 316) upon request for more aggressive applications,
such as offshore duty. Its special valve design provides a high
rate of airflow. Like most CEJN breathing air couplings, Series
346 offers one-hand operated connection, an integrated safety feature that guards against unintentional disconnection, a grip-friendly locking sleeve, and a broad range of connections.
