In a previous post two days ago, I spoke of the difference in the
advertised specs vs. the specs in the manual on the JDS Dust-Force dust
I spoke with the owner of JDS on the phone today, and he explained the
Woodcraft and Amazon are advertising the specs on the machine as
equipped with the standard 30-micron bag, but the version they are
selling has a 1-micron bag upgrade. This upgrades filtration but
degrades airflow performance. JDS has given them the new specs for the
1-micron bag...they are just not using them.
The proper specs are as follows:
12" static pressure
7.2" static pressure
Woodcraft and Amazon took the best specs for both and combined them.
As to the db rating (87 vs. 77), he said the proper figure is 77, and
that the manual has a misprint. (I think I believe him here, too,
because the first shipment of motors had current draw of 24 amps
stamped on the motor plate.)
While I am still not particularly happy with my transaction, my beef
lies with Woodcraft, not JDS.
