Just a little feedback.
My DC setup is now set up in a closed chamber so virtually all the filtered air returns to the shop. I have a Wynn filter I got before the ones with the internal mechanism to knock dust off the filter was offered. I always recommend the newer type filter, Grizzly makes one.
I have shortened all hoses, but for practical reasons, still have the 27 foot flex hose, however, all my tools are within 10 feet of the DC so the hose is rarely fully extended except for shop cleanup There are no longer any sharp turns in the hoses and connectors. The space is too tight to use pipes or tubes. I take the point about other brand DC units, but have yet to have any need to upgrade from the basic HF unit. It works fine for me, and for lots of us. I have a split shop, my (Laguna) band saw, jointer, planer and track saw are in the garage, where I have the second HF unit with the Rockler chip collection setup. This rolls outside for use. So for me, buying two brand name units, such as the Jet, is prohibitive given my present (lower) income.
I have not made any modifications to either DC unit. They both work well for me as is. I mention the possibility of a different impeller only because it is available and some members have made that modification. I suggest the HF to anyone for whom cost is an issue. I believe, as a throat cancer survivor, that any dust collection is better than none, and that it should be an early addition to every shop. I also know that given a choice between an expensive DC unit an another important tool, that the DC usually loses to the tool.
Please note that I suggest placing the basic bag filter unit outside (in a dry area). In my shop shed, it is in an enclosed space next to the shed, with a 4 inch Rockler through the wall tube going through the wall. And yet, I still wear a simple dust mask even though the return air is filtered twice.
I recently added a Super Dust Deputy to my shop shed system, which has further enhancet the DC efficiency. The hoses are all shortened and straightened. The picture I post still shows the longer hose. I lost my camera so haven't taken a new picture yet.
FYI, the Wixey now uses two AAA batteries, has very long battery life (still on my first set after 2 years) and shuts off just fine, although I routinely turn it off manually. It also now has a rear illuminated readout, which makes it easier to read. I don't know the other brand but assume Stick's recommendation is good. Wixey changed the battery source in most of their digital tools several years ago because button batteries go dead so fast. I also use my Wixey to tune up my sliding miter. And the Wixey unit for planers also uses the AAA batteries now.
In addition to my small Rikon band saw (which I use all the time), I have a Laguna 14/12 in the garage, which is mainly for resawing. The jointer is a 6 inch Powermatic, the planer is a DeWalt 735. I also have a Laguna 10 inch hybrid table saw in the shop. Great tool maker. Each tool puts out lots of sawdust and a DC unit is a must.
I'm posting this because I felt a bit attacked a few posts back. My shop, tools and skills have evolved over time and I've done my best to get the best performance I can given my budget.
I like the Jet 650, about $560, which has the 1 micron filter and the crank to clean it. It also has a smaller footprint than the HF. With a chip collector it is a fine unit. The 1100 model is very similar to the HF unit and has a 5 micron bag (same as HF). I think it has a little more hp than the 650. You can get the 1200, 1100 but with a canister filter for about $800.
On sale, the HF was $162, the canister filter is about $180 or so for a total of $342. My two HF units, one with canister filter the other without, added up to $504, and they work just fine.
No one is making anyone buy anything, it's completely each member's choice. Most of us are posting about gear we actually have and use.
