A media folding machine is the second machine used to make HEPA or ASHRAE cell/box type filters. Aluminum separators are staged on each side of the machine and the operator inserts them as this pleater makes the large folds and the table descends to hold the large pleat pack.
Aluminum mesh or stainless steel can be run on a GMD gear pleater to make strainers and other mesh type filters.
Industrial air filters, off road heavy equipment air filters or pool/spa filters need to have the pleated filter pack seamed together to form a cylindrical element. With our side seaming machine hot melt glue or ultra-sonics can be used to bond the pleat pack ends.
