Series 418, a 100% polyester wipe knitted from filaments, is one of the classic cleanroom wipes for more critical areas, both in microbiological controlled areas and in purely particle controlled areas. After cutting (cold cut edges), the wipes are professionally decontaminated in a cleanroom laundry and packed under ISO 4 conditions (EN ISO 14644-1). The wipes, even if they are made of 100% polyester, have a high absorption capacity. The robust polyester knitted fabric shows its strength on rougher surfaces or on sharp-edged objects and/or surfaces. Due to the cleanroom-compatible post-cleaning, the wipes have relatively low levels of ionic and metallic contamination.
Facts
Polyester
Knit, 100% PES, cold cut edges, robust
Properties
- 100% polyester
- knitted fabric made of filaments
- unsealed, cold cut edges
- decontaminated in a cleanroom laundry
- double bag packed in a cleanroom (air cleanliness class ISO 4)
Advantages
- very robust cleaning wipe
- more absorbent than most single-ply polyester wipes
- low ionic and metallic contamination due to decontamination
- very wide range of applications
validated sterile available
Applications
- cleaning wipe for critical and non-critical areas
- well suited for angular, rough surfaces and objects that might prematurely damage a non-woven fabric wipe
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.
