RK DuoLine Clean – linear actuators for use in cleanrooms
Tested to EN ISO 14644-1
RK Rose+Krieger has optimised its RK Duoline profile linear unit for use in cleanrooms and now offers spindle and belt-driven RK Duoline Clean linear units, with or without vacuum suction, in the popular sizes 60 and 80. A total of eight different versions passed EN ISO 14644-1 testing to be awarded cleanroom certification in the global classifications 1 (RK Duoline Clean 60 SU with 0.5 m/s vacuum suction) to 5 (RK Duoline Clean 80 Z without 0.5 m/s vacuum suction). All the requisite cleanroom suitability tests were conducted at the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) in Stuttgart.

Cleanroom axis design to the sizes 60 and 80
Cleanroom production is an essential aspect of the manufacturing process for industries such as the semi-conductor industry, photovoltaics, microelectronics, aerospace technology, not to mention the automotive industry. Naturally the requisite cleanroom classifications vary as a result. Since cleanroom production rarely involves moving heavy loads, RK Rose+Krieger has dedicated its cleanroom axis design to the sizes 60 and 80. The result is a total of eight different linear units, each tested at three different speeds:- RK Duoline 60 S – RK Duoline 80 S
- RK Duoline 60 SU – RK Duoline 80 SU
- RK Duoline 60 Z – RK Duoline 80 Z
- RK Duoline 60 ZU – RK Duoline 80 ZU
