By taking targeted preventive measures, you can use our drives in even the most extreme environmental conditions. A combination of interior treatment and surface protection provides optimal protection for motors and gear units. Be prepared.
Durable drives with preventive measures up to OS4
Our gear units and motors can provide additional protection against typical corrosive agents in industrial environments, such as moisture, oils, dirt and chemicals, than what is provided as standard. Additional treatments and special materials allow these devices to be used even in extreme conditions.
Select from among our optional preventive measures. Use our drives in any atmosphere, from those with low moisture and contaminants to environments with regular wet cleaning using acidic and caustic agents.
Our surface protection levels range from standard to levels OS1 to OS4, corresponding to the corrosivity categories C1 (negligible) to C5-I (severe).
It is not only our standard components for which optional preventive measures are available. Both the aseptic motors of the DAS.. series and the ASEPTICplus® drive package are already optimized for use in sensitive, hygienic production areas.
Find out more about the various surface protection options. Sample applications help you to select the right protection option for your gear unit or motor.

KS corrosion protection
Features
- All retaining screws that must be loosened during operation are made of stainless steel.
- The nameplates are made of stainless steel. Various motor parts are coated with a finishing varnish.
- Flange contact surfaces and shaft ends are treated with a temporary rust preventive.
- Clamping straps as additional measures for brakemotors
OS surface protection
Features
Instead of standard surface protection, motors and gear units are optionally available with OS1, OS2, OS3 or OS4 surface protection. This equips the gearmotors for use in different ambient conditions.
You can also choose additional special measure “Z.” This means that large contour recesses are filled with rubber before painting.
Areas of application
| Surface protection | Ambient conditions/sample applications | |
|---|---|---|
| Standard |
 |
For machines and systems within buildings and interior rooms with neutral atmospheres.
|
| OS1 |
 |
For environments prone to condensation and atmospheres with low humidity or contamination. E.g. outdoor applications under a roof or other protection device.
|
| OS2 |
 |
For environments with high humidity or moderate atmospheric contamination. E.g. applications outdoors subject to direct weathering.
|
| OS3 |
 |
For environments with high humidity and occasionally severe atmospheric and chemical contamination. Occasional acidic or caustic wet cleaning. Also for applications in coastal areas with moderate salt load.
|
| OS4 |
 |
For environments with permanent humidity and severe atmospheric or chemical contamination. Regular acidic and caustic wet cleaning, also with chemical cleaning agents.
|
| Aseptic motors of the DAS.. series OS2-OS4 as needed |
 |
Suitable for dry or wet hygienic areas with average atmospheric contamination. Also suitable for particularly dusty environments.
|
| Aseptic motors of the DAS.. series with ASEPTICplus® drive package OS4 |
 |
For hygienic areas in the food and beverage industry with permanent humidity, regular acidic or caustic wet cleaning with chemical agents and pressure cleaning.
|
| High-protection coating HP200 |
 |
Suitable for hygienic areas in the food and beverage industry with regular acidic or caustic wet cleaning. Anti-stick properties support the cleaning process even in inaccessible areas. Sample applications:
