Festo air preparation range

The Festo air preparation range provides a certified and tested unit that can be integrated into new or existing circuits, either standalone or housed in an air-preparation module. As a supply device providing a safe exhaust function, it offers a number of possible applications and benefits.

The safe exhaust valve with integrated soft start is used as a central unit to supply machines and installations with compressed air. Based on a dual 3-/2-way configuration with integrated safety relay, it is a self-checking, inherently safe redundant system in accordance with AS 4024 Category 4 and ISO 13849-1 Performance Level ‘e’ ensuring the pneumatic safety objective of a ‘safe exhaust function’, even if malfunctions occur in the valve.

The redundant design of the valve provides single-fault safety. Even if a fault occurs in the valve, this does not lead to a loss of safety function in terms of safe exhausting of the installation.
