Clean Room Preparation
There is no clean room ‘rating’ for motion control products just individual compatibility with class of clean
rooms. The compatibility is also dependant on measurement location. A point directly below a component
may have a different particle count than at a side location. In an effort to clarify the class of clean room
that our products can be used in with out affecting the overall rating of the clean room, Daedal provides a
Clean Room Class Compatibility chart for product intended for use in such environments. Due to the
moving magnet design of the MX80L, minimal particle generation occurs during operation. MX80L tables
with clean room preparation were tested in Daedal’s vertical laminar flow work station which utilizes ULPA
filters to produce an environment having a cleanliness of class 10 prior to testing. Tables were tested in a
variety of orientations with sampling both below the table and at the carriage mounting surface with a
particle counter capable of measuring 0.3 µm diameter and larger particles. Based on results from testing
following the 209E Federal Standard, the following chart shows the expected clean room compatibility of
the MX80L with Class 10 clean room prep. Consult factory for details on test methodology and results.

* Compatibility is defined as not affecting the clean room class rating with the addition of this product for classes shown.
For example a MX80L with 50mm travel with a velocity of 500mm/sec will not effect a class 10 clean room or higher.
The Class 1 rating in the table refers to class 1 levels of 0.3µ and larger particles detected in Daedal’s Class 10
chamber. For complete class 1 compatibility, the particle count for the 0.1 and 0.2µm particles would also need to be
taken into consideration.
