Re: ? Members with Grizz 2 HP DC
I don't have this cyclone, so I can not comment on my experiences (I have a 2HP JDS Cyclone). You'll want to replace this unit's 2.5 micron filter bag with a 1-micron filter for your health's sake. 2.5 microns is better than the 5+ micron bags that many single-stage DCs ship with, but still not adequate. For optimal performance you'll really want to replace the felt filter material with a 1-micron canister filter, then you should have a decent single-stage dust collector.
If your wallet allows, I would encourage you to seriously consider a 2HP cyclone DC. The upgrade to a cyclone is well worth the money and you will never regret the investment.
A well-built cyclone DC will always out-perform a single-stage DC. Plus, with a cyclone you won't EVER have to worry about the consequences of large debris (including wood, screws or nails) getting sucked into your DC. With a single-stage DC these large debris items have to physically pass through the impeller (fan), with a cyclone they just make a little racket as they bounce against the cyclone funnel before falling harmlessly into your primary waste bin! You also benefit from an increase in static pressure, and thus suction, with a cyclone (more efficient impeller), which means more airflow through the same hose/opening. My 2HP cyclone can keep up with my 13" planer with 25ft of 4" flexible hose between it and the planer or my 8" jointer with 10ft of flexible hose.
If you have not already done so, this is also a great time to look into an ambient air cleaner for your shop. A dust collector (with 1-micron filter) of any type and a 1-micron ambient air cleaner really complement one another. The dust collector keeps most of the dust out of the air to begin with by capturing it at the source, preventing it from becoming airborne, while the air-cleaner mops up the fine dust that does escape primary capture. I use a JDS 750-ER (750CFM filtered, 1050CFM w/o filters -- mentioned because many manufactures specify maximum CFM with filters removed, which is a pointless number really).
