Series 414, a 100% polyester wipe knitted from filaments, is one of the classic cleanroom cleaning wipes, for more critical areas in both microbiological controlled and exclusively particulate monitored zones. After cutting (cold cut edges), the wipes are professionally decontaminated in a cleanroom laundry and packaged under ISO 4 conditions (EN ISO 14644-1). The wipes – even though they are made of 100% polyester – have a decent absorption capacity.
The robust polyester knitted fabric shows its strength on rougher surfaces or with sharp-edged objects and/or surfaces. Due to the cleanroom-compatible decontamination, the wipes have relatively low levels of ionic and metallic contaminants. In addition, there is a low load of non-volatile residues (NVR) and good chemical resistance.

Product recommendation based on cleanroom classes
Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.
A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
