When working in a cleanroom, it is of the utmost importance to have and keep the room free of dust particles. Score chairs have been tested by the Fraunhofer Institute and comply with the directive DIN EN ISO 14644_1, ISO class 4 (Class 10 according to the US Federal Standard 209E). These chairs are available in ESD leatherette or polyurethane, which will not disperse or attract dust particles. If necessary, the Score chairs can be equipped with a Hepa filter. This filter ensures that, when you sit down or move on the chair, the dispersed air is always filtered and no dust particles will be released in the room.
