Through Air Dryers

Through-Air dryers will push or draw the drying air though a porous web that is supported by an open mesh conveyor belt or chain. Web widths have varied from 10” to 200” (5 meters), yet all require an even distribution of drying air in the machine direction and cross-machine direction. ASI Through-Air dryers can be found in many industries including fiberglass mat, filtration media, abrasives and non-woven products.


Roll Support

A multi zone Through-Air dryer used in the production of fiberglass mat. It is designed for high speed production with a very low temperature variation in the cross-machine direction. The product web is first dried and then cured.
