series LS

Compressed air safety quick-release coupling system for a wide range of applications, designed for the distribution of compressed air in industrial and commercial environments.

These compressed air safety quick-release coupling systems prevent premature release of the coupling thanks to their pressure-controlled release mechanism. The fitting can only be mechanically disconnected once the operating pressure has dropped below approx. 1.5 bar / 220 psi. This technology prevents incorrect operation, i.e. the dangerous ‘whip effect’ is avoided, in accordance with DIN EN ISO 4414.
