Dave, yes, the pad is the only difference. The pads and abrasives are forward and backward compatible. The new pad works on old sanders, the old pad works on new sanders. The new abrasives work on the old pad, the old abrasives work on the new pad. Here's my article on Multi-Jetstream from December SysNotes.
Festool is in the process of transitioning to a new design for pads and abrasives on its 6" (150mm) sanders. This next step in the evolution of Festool's patented Jetstream technology, called Multi-Jetstream, continues to improve on the phenomenal dust extraction capabilities that you come to expect from Festool sanders. If you'd like to know more about the new Multi-Jetstream technology, you can view a video about it on YouTube.
Festool Multi-Jetstream Technology
The Hole Story.
Building on existing industry leading performance, this next generation design incorporates a modified hole pattern that increases airflow and results in even better dust extraction efficiency. In addition, the new pads incorporate an enhanced, heat-resistant StickFix design, extending both pad and abrasive life considerably.
Quick Facts.
* Pricing for Multi-Jetstream pads and abrasives will be the same as existing products they replace.
* Air movement is increased through and across the pad, increasing dust extraction and lowering pad temperature thus reducing wear.
* Applies to 6? (150 mm) only ? RO 150, ETS 150, LEX 150 sanders.
* New paper works on old pads ? backwards compatible.
* Old paper works on new pads ? forward compatible.
* Updated packaging for Multi-Jetstream abrasives.
Multi-Jetstream AbrasivesMulti-Jetstream Pads.
Only the pads and abrasives are changing - not the sanders. Existing RO 150 and ETS 150 machines can be converted to Multi-Jetstream by simply switching pads.
* More holes in the face, as well as channels in the pad, for increased air movement.
* Even more heat resistant than current design for longer pad life.
* Attach in the same manner as existing pads
* Work with Jetstream and Multi-Jetstream abrasives
Please note that there are new product numbers for all sanders, pads, and abrasives that have changed to the new Multi-Jetstream technology. Visit your preferred Festool dealer for more details.
