A gap that engineers have worked around for years
Festo has long been a go-to for pneumatics and general automation — excellent technology, strong support, a broad portfolio. But when the conversation turned to electric cylinders and motors that needed to survive daily high-pressure washdown, engineers specifying food, beverage, and pharmaceutical lines had to look elsewhere.
"Stainless steel" and "washdown-rated" are not the same thing — and that distinction has limited Festo's electric motion portfolio in some more hygienic F&B applications. Until now.
The Festo EPRF stainless steel electric cylinder and EMMH-AS stainless steel servo motor are purpose-built for broaden - Festo's EA Portfolio into these washdown zones.
What F&B Environments Actually Require
This is one of the most common conversations we have with engineers specifying electric actuators for food and beverage lines. The assumption is that "stainless steel" means washdown-ready. It doesn't — not on its own.
Per FSMA guidelines, hygienic design has three non-negotiable requirements:
Cleanability
Smooth surface finish with no crevices for bacteria to accumulate
Drainability
No geometry that traps water, dirt, or biofilm between cleaning cycle
Material selection
Food-safe and corrosion-resistant at every contact point, inside and out
An IP69K rating alone doesn't guarantee all three. What matters is how that rating is achieved — and what materials and design principles are behind it.
What Festo Built — and Why It Checks the Boxes
The EPRF cylinder and EMMH-AS motor were engineered together as a matched hygienic system. Every design decision traces back to the environments they need to survive.
316L stainless steel housing (1.4404)
Both products are housed in 316L stainless, rated Corrosion Resistance Class 4 — Festo's highest classification for particularly high corrosion stress. 316L stainless steel provides excellent resistance to common food-processing cleaning agents, humid environments, and many corrosive washdown conditions.
IP69K Rating Sealing - dual seal technology
The EPRF uses two IP69K piston rod seals connected in series — not a single seal with a backup. A pressure equalization connection safely discharges air to the outside of the food zone, preventing condensation buildup inside the cylinder.
NSF-H1 certified food-grade grease
NSF-H1 certification means the lubricant is approved for incidental food contact. Both products utilize NSF-H1 food-grade lubricants suitable for incidental food-contact environments — not just "close enough" — which matters at audit time and in regulatory reviews.
Laser-engraved rating plates
Both products use laser-engraved nameplates rather than adhesive labels. Labels degrade under repeated washdown. Engraving doesn't. It's the kind of detail that tells you a product was designed for the environment, not adapted to it after the fact. Commonly found onon equipment intended for repeated washdown exposure.
Performance Specs — Not a Compromise Product
Some washdown-rated products achieve their environmental protection at the cost of performance. These don't. The numbers are competitive with standard (non-hygienic) electric cylinders.

- Peak torque up to 59 Nm
- Battery-free multi-turn absolute encoder (EnDat2.2) — no homing required on startup
- Single-cable solution (OCP) with integrated pressure equalization hose
- Optional holding brake for vertical axes
A Complete Servo Solution from One Source
Here's what makes this more than just two new products. Festo built the entire drive stack to match — and sourcing everything from one place removes significant engineering overhead, especially for OEM machine builders.
Everything in the hygienic servo solution:
|
Component |
Product |
|
Cylinder |
EPRF stainless steel electric cylinder |
|
Motor |
EMMH-AS stainless steel servo motor |
|
Drive |
CMMT-AS-MP multi-protocol servo drive |
|
Cables |
Food-grade hygienic motor cables |
|
Mounting |
Stainless motor mounting kits (axial & parallel) |
|
Protocols |
Profinet · EtherCAT · EtherNet/IP · Modbus |
The CMMT-AS-MP supports all major fieldbus protocols in a single drive hardware platform — integration with your existing PLC or motion controller isn't a negotiation. Commissioning runs through the Festo Automation Suite.
For OEM machine builders: piecing together a hygienic cylinder, washdown motor, and compatible drive from three different vendors — then validating the system holds its IP rating at every cable entry point — is real engineering overhead. A matched solution from one source removes it.
Industries and Applications
The most common applications are in food and beverage, but these products were designed for any environment that combines precision motion with demanding washdown or corrosion exposure.
Food & Beverage:
- Beverage filling
- Meat and fish handling
- Cheese processing
- Kitchen automation
Other industries:
- Pharmaceutical manufacturing
- Packaging lines
- Battery manufacturing
- Pulp and paper / mining
- Freezer and cold storage environments
- Car wash equipment
The common thread isn't the industry — it's the operating condition: high-pressure cleaning cycles, aggressive chemicals, moisture ingress risk, and positioning accuracy that needs to hold over the full life of the machine.

FAQ
Does IP69K mean the same thing as "washdown-rated"?
Not necessarily. IP69K is a protection rating for high-pressure, high-temperature water jets — but it doesn't speak to material compatibility with cleaning chemicals, surface cleanability, or whether internal lubricants are food-safe. The EPRF and EMMH-AS are designed to meet all of these requirements together: IP69K sealing, 316L stainless construction, NSF-H1 grease, and smooth-surface hygienic design principles that support cleaning and sanitation procedures.
Can the EPRF and EMMH-AS be used in direct food contact zones?
Yes. Both products are documented as suitable for direct food contact. The 316L stainless steel housing, NSF-H1 certified grease, and dual-seal rod sealing system are all specified for hygiene-critical zones. Application-specific requirements should always be reviewed against your facility's food safety plan.
Do I have to use Festo's drive with these products?
No. The EMMH-AS motor integrates with third-party PLCs and motion controllers. That said, specifying the complete Festo servo solution — cylinder, motor, drive, cables, and mounting kits — provides validated system performance and simplifies commissioning through the Festo Automation Suite.
Is the EMMH-AS encoder battery-free?
Yes. The EMMH-AS uses a multi-turn absolute encoder with EnDat2.2 interface that operates without a battery — no homing cycle required on startup and no battery to replace. Both are meaningful advantages in food environments where maintenance access can be restricted and unplanned downtime is costly.
What mounting options are available for the EPRF?
Six mounting options (M1 through M6) cover flange mounting with threaded holes, flange mounting with through-holes, foot mounting, rear trunnion mounting, and combinations of flange plus foot mounting. All front flanges are rotatable, so positioning can be freely selected for your specific installation geometry.
What industries use these products beyond food and beverage?
Common applications outside F&B include pharmaceutical manufacturing, packaging lines, battery manufacturing, pulp and paper, mining, freezer and cold storage environments, and car wash equipment. The Corrosion Resistance Class 4 rating — the highest available — reflects the breadth of environments they're designed for.
