FAQ

Question?
What does the '-P-A' suffix in the type number DSNU-40-160-P-A signify?

The '-P' indicates that the cylinder is equipped with elastic cushioning rings at both ends of the stroke. This helps to reduce noise and absorb impact energy at the end positions. The '-A' signifies that the cylinder has a permanent magnet on the piston, making it suitable for position sensing with external proximity sensors.

Question?
Is this cylinder suitable for use in a food processing environment?

The standard DSNU cylinder has a high-alloy steel barrel and die-cast aluminum end caps. While it offers good corrosion resistance, for direct food contact or washdown areas, Festo typically recommends specific variants with higher-grade stainless steel (like the CRDSNU series) and food-grade lubricants. Always check the specific requirements of your application.

Question?
What is the required air quality for the DSNU-40-160-P-A to ensure a long service life?

Festo specifies compressed air in accordance with ISO 8573-1:2010 [7:4:4]. This means the air should be filtered to remove solid particles, water, and oil. Using properly prepared air (e.g., with a Festo FRL unit) is crucial to prevent premature wear of the seals and ensure reliable operation. Both lubricated and non-lubricated operation is possible.
