Industrial Nanofiber Production Line (INFL)

FNM Industrial Nanofiber Production Line (INFL) is a polymeric/ceramic nanofibers producer machine in industrial scale for various applications. INFL uses 4 to 8 electrospinning units, based on the customer requirement. In the industrial production line, the electrospinning parameters and conditions such as spinneret and collector parameters, working distance, linear movement speed of the used substrate, working temperature and operation time could be controlled using an integrated advanced control system. The machine offers excellent safety for users with respect to the handling of high voltage power supplies and chemical solvents.
Using this production line, nanofibers could be deposited on different substrates in industrial scale. INFL is widely used for producing nano-filters and nano-respiratory facemasks. Depending on the number of electrospinning units, nanofiber coating rate will be about 50-800 square meters per hour.
