The difference between FESTO elastic buffer plate and air buffer.

After FESTO cylinder model, there is -P for elastic buffering and -PPV for air buffering. Elastic buffering means that the piston has a rubber pad at the end of the stroke to play a buffering role, which is usually used when the cylinder stroke is very short, such as ADVU compact cylinder. Air buffering means that when the piston moves to the end, the exhaust volume of the exhaust cavity is less than the intake volume, which will reduce the cylinder speed and achieve the buffering effect. This kind of cylinder has small vibration and long service life. The specific choice depends on your working conditions.
