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 collector.
I spoke with the owner of JDS on the phone today, and he explained the issue.
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:
30-micron bag: 1250 CFM 12" static pressure1-micron bag:
1115 CFM 7.2" static pressureWoodcraft and Amazon took the best specs for both and combined them. Nice.
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.
