Air cushion pad
1. Air cushion integrated into the sanding pad
The sanding pad is designed as a tub into which an inflatable cushion is inserted. It is covered by the sanding pad insert, which consists of a steel strip, felt and a graphite cloth. The sanding belt runs across the graphite cloth.
It is primarily used in solid wood processing. Thin veneers, lacquer finish etc. are preferably processed with electronic sanding pads.
2. Free air cushion AEROSTAT
In this method, compressed air flows against the sanding belt through nozzles in the sanding pad. Thus, it is inflated by up to 3 mm. According to the manufacturer Johannsen's information, better sanding results occur than with integrated air cushions. This method is a worldwide patent of Johannsen.
