This document provides recommendations on how the load voltage of the valve terminal MPA-FB-VI, MPAL, VTSA-F-CB, VTUG and VTUX can be safely switched off. It is planned to expand this document with information on other valve terminals.

This information brochure describes the tools and repair accessories required to assemble, maintain and repair Festo products. Here you will find part numbers for tools, lubricants, greases etc.

An artificial bird is introduced which was developed using two new

features in biologically-inspired flight, active torsion and partially linear

kinematics. Active torsion rests on well established theoretical

predictions in unsteady aerodynamics. The concept of partially linear

kinematics is inspired by zoological observations on flying locusts.

When the wings flap upwards, the servomotor for the active torsion

turns the outer wing from a positive angle of incidence within

a short fraction of the flapping period into a negative angle of incidence.

Between the turning points the angle of torsion remains

constant. Numerical calculations confirm the expected benefits

compared to passive torsion.

Great care must always be taken when compressed air comes into contact with food, because compressed air is not clean by nature.   On the contrary, solids and particles are present almost everywhere in the form of dust in various concentrations. Water, in the form of natural atmospheric humidity, is released in large quantities when the compressed air cools down. And thus compressed air quality in accordance with the requirements of the respective application provides best possible safety for foods, consumers and food producers.

This white paper includes information on:

- Compressed air preparation and compressed air quality classes

- Filter cascades for typical applications
