Protection Box for Air Preparation 18/08/2025
Simply protected!
The conditions in many manufacturing areas, such as the splash
zone in food production plants, place a lot of stress on service unit
components. Cleaning agents and water jets attack the surfaces,
screws and pressure gauges. With this stainless steel protection
box, Festo offers a simple and low-cost solution to securely protect
the compressed air preparation components.
