Series 304-1, a polyester-cellulose non-woven wipe, is versatile, both in microbiological controlled areas and in purely particle controlled areas. Although it is made of a non-woven fabric, the wipe has a certain abrasion and tear resistance (even when wet).
The cloth material combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a happy medium in terms of costs. The hydro-bonded non-woven fabric is not quite as clean in direct comparison to the series 300 and the series 302. In addition, the wipe has good chemical compatibility with different solvents and cleaning agents.
The blue dyeing enables the user to check how far a possibly aggressive liquid has spread in the 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.
