Introducing Festo’s IP69K Stainless Steel Electric Cylinder
Festo Introduces the IP69K Stainless Steel Electric Cylinder EPRF‑BS
As hygienic manufacturing environments become more demanding, automation components must deliver uncompromising durability, efficiency, and cleanliness. Festo’s latest product release: the stainless steel electric cylinder EPRF‑BS, paired with a full IP69K servo solution, raises the bar for electric motion solutions in food, beverage, pharmaceutical, and packaging applications. One of the few offerings in an all‑in‑one, washdown‑ready electric solution of this caliber.
Built for the Most Demanding Hygienic Environments
The EPRF‑BS stainless steel electric cylinder is designed for environments exposed to frequent high‑pressure washdowns, aggressive cleaning agents, and strict hygiene requirements. With an IP69K protection class and a smooth, contamination‑resistant surface, the EPRF‑BS is suitable for direct food contact and cleaning‑in‑place (CIP) procedures.
Key hygienic design features include:
- Smooth, easy‑to‑clean surfaces with no sharp corners
- Dual IP69K piston rod sealing technology
- Integrated pressure equalization connection to prevent internal condensation
- NSF‑H1 certified grease for hygiene‑critical applications
These features work together to minimize bacterial growth, reduce downtime, and ensure long service life in harsh production environments.
Stainless Steel Construction
The EPRF‑BS has 316L / 1.4404 stainless steel housing, delivering corrosion resistance even in highly corrosive washdown zones. The robust yet compact design eliminates the need for additional protective shielding, helping manufacturers maximize performance in limited spaces while maintaining compliance with hygiene standards.
Flexible, Compact, and Easy to Integrate
Festo’s EPRF‑BS offers integration flexibility, making it ideal for both new designs and pneumatic cylinder retrofits.
Design flexibility includes:
- Six mounting options (M1–M6)
- Axial or parallel motor mounting
- Rotatable front flanges for custom positioning
- Laser‑engraved rating plate for long-term durability
All of this allows engineers to quickly adapt the EPRF‑BS to individual machine layouts without compromising hygiene or performance.
A Complete IP69K Servo Solution
Together, the EPRF‑BS and EMMH‑AS form a powerful, fully washdown‑ready electric drive system that delivers:
- Precise and reliable motion control
- Simplified installation with coordinated components
- Consistent IP69K protection across the entire drive assembly
This integrated system helps reduce engineering effort, speeds commissioning, and ensures long‑term reliability in hygiene‑critical zones.
A Smart Upgrade from Pneumatics
For manufacturers looking to move beyond traditional pneumatic cylinders, the EPRF‑BS offers clear advantages. Electric actuation provides greater motion control, improved efficiency, reduced air consumption, and enhanced repeatability, all while maintaining the hygiene standards required in sensitive production environments.
