UFS746
Unico’s Cleanroom Foam Swab FS746 uses a medium-sized sponge head and handle. The sponge head is made of 100PPI open-cell polyurethane, which has good liquid absorption and locking ability. The handle is constructed of 100% polypropylene and provides strong support during cleaning. The sponge cleaning swab FS746 is cleaned in a Class 10 clean room facility, and hot-press lamination technology can avoid adhesive contamination. It is a good choice for cleaning hard-to-reach areas, cross sections and key parts of the machine. FS746 wiper can be used to clean and wipe the lens of laser marking machine, it can effectively remove the oil stain, dust and residue on the lens.
