The latest range of air logic devices, developed and manufactured by Parker Hannifin, now offers engineers an extremely efficient and cost effective modular system that can improve productivity, reliability and profitability of pneumatic circuits in a wide range of applications. In particular, the latest air logic devices can be used as an alternative to conventional PLCs, for managing smaller or less complex pneumatic circuits, and in areas where there is no electrical supply or where compliance is required with ATEX directives.
