I ordered a 0.3 micron replacement filter from Wynn Environmental to replace my Jet DC1100 30 micron bag.
Originally I was going to make a simple review for people to benefit from my experience with the new filter I got… but since it had gotten a bit more complicated, I figured this is blog-worthy, and the ‘regular’ review will follow once I experience more the performance of the filter.
Disclaimer: I have had nothing but great experience from Wynn Environmental, from their information advertising on their website, to the ordering process over the phone. the complication of my filter replacement is purely caused by my missing of information, and being over-excited about this upgrade that I didn’t take the time to do it one step at a time.
So… on with the story:
I got my Jet DC1100 a while back off of craigslist at a bargain price after hearing good things about it, with the plan to eventually replace the lousy 30 micron filter bag with a better cartridge filter.
After doing much research online (Bill Pentz site, Wynn Environmental site, Penn State Industries, LJ, FWW, PWW, and anywhere else I could get info) I decided that the Wynn Environmental replacement filters would work best for me. this came down based on price (~$103), filteration quality (0.3 micron), and the fact that their set was designed to retrofit single-stage-dust-collectors like mine.
I ordered the set from WynnEnv. and was awaiting patiently for it to arrive, which it did very shortly. I was so ready to just take it out of the box, take off my bag filter, pop the new cartridge filter on, and call it a day.
thats when I had to wake up and smell the coffee. the cartridge filter wouldn’t fit inside my collector easily. being excited and pumped to see this thing installed I tried to bend the top of the dust collector wider to accommodate the cartridge size to no avail. Although the diameter size difference was very minor, it was large enough to block the catrridge from going in. unfortunately the top of my dust collector is slightly bent now – minor, and only cosmetic – but still , kinda sucks.
At this point the party was over. I figured I need to research this some more, and find another solution.
After going back to the Wynn Env. site, I found out that the Jet DC1100 has 2 models.. a new one in which their filter fits easily, and an older version that has a smaller rim in which the filter will NOT fit. they suggest a fabrication of a doughnut ring to overcome this size matter. I was really hoping not to have to fabricate anything, but I guess the important thing is to have the 0.3 micron filter – so fabrication here we come.
The fabrication calls for a doughnut ring to be made that will seal the top of the dust collector and will set a platform for the filter to sit on, with an opening large enough to match the filter opening.
I have decided to make this ring out of MDF which I had at hand, which will also have a nicer look to it then plywood.
NOTE: while working with the MDF I was working with a shop-vac (set with HEPA filter AND filter bag) hooked to the router, AND a filtered face mask
I used the BOSCH edge-guide with my router as a circle jig by taking off the guides’ edges – this is an awesome edge guide and I find it very useful in many applications.
the first cut I made was a bullnose slot 1/4” deep (2 passes, taking 1/8” in each) this slot is where the dust collector top will be mounted in. Since this is not a through cut, and is located inside the finished ring, I cut this first before removing any material from the ring – giving me a more stable (larger) area to support the router (before taking any of that material out). The diameter of the slot was set to match the diameter of the top of the dust collector
After routing the slot, I added 1” to that diameter, and made a cut through (3 passes, taking off 1/4” in each pass). After I had the disk cut out, I then cut the inner opening 2” inside of the slot diameter (again 3 passes, taking 1/4” in each pass)
which left me with this doughnut adapter:
to air-seal between the doughnut and the disk I filled the slot with silicone sealer (used for kitchens/baths) and placed it on top of the dust collector, once the silicone dries it will be sealed, but can be ripped out if necessary in the future.
after the doughnut was on the dust collector, I centered the filter on top of that, and with hooks fastened it to the dust collector from the inside.
Filter part is done… now lets replace the fabric collection bag with the plastic ones – those are much better (air tight, and transparent)... alas these are simply nylon bags and are wider then the dust collectors’ body diameter, plus there is no way to clamp them to the dust collector – luckily the filter bag was clamped to the dust collector with a ring clamp which I was able to use for the nylon bag. to be honest – it was a nightmare clamping that thing to the machine as the nylon kept on slipping down while I was trying to get the clamp around it and clamp it in place. Wynn suggests to use tape to hold the bag in place while clamping it -which works, but it would have been nice if this was more ‘user-friendly’. I might opt to take the plastic bag, and place it inside the original Jet fabric collector bag for easier mounting.
so Here is the outcome:
All in all, not the installation process that I had in mind, not the look that I was aiming for (doughnut), first impression of bag replacement is kinda iffy, but we’ll see how that goes. going down from 30 micron filteration to 0.3 – PRICELESS! (and all for less than half the cost of a brand name cartridge dust collector setup that only goes to 1-3 micron)
Can’t wait to fill that bag up already!
I have painted the disk with rustoleum (appliance epoxy) and it matches (almost perfect) the Jet finish paint:
I also took the clear plastic bag from Wynn Env. and place it inside the original Jet cloth lower bag which has a rubber strip on the top to hold it in the DC – this way I get the plastic bag efficiency, with the built in ease of taking the bag off and putting it back on (no need for metal rings and clips)
