Design: The compressed air steel couplings offer many advantages over standard brass couplings: easy one-handed operation with low coupling force, high flow rate due to minimal pressure losses, durability from surface-treated and hardened components with tight manufacturing tolerances, as well as cost-effectiveness – the payback period is a maximum of 2 years. The eSafe safety coupling complies with ISO standard 4414 and EN 983. It first vents and then uncouples (no whip effect). New, improved one-handed operation. Flow rate: 2250 l/min, maximum operating pressure 16 bar. Note: The CEJN series 320 complies with Eurostandard 7.6 (nominal diameter 7.6 mm, Euro profile) and is compatible with all common systems.
