Harbor Freight DC Mod Harbor Freight DC Mod No-picture-s Click the pictures to enlarge them

Hi, First time posting,Long time reader I just finished my HF DC mod.
When I first added a seperator with Thein
baffle I noticed a big drop in suction. Once I eliminated all bends and flex hose
the collector seem like I gained all suction
back. (Plus saved a lot of room) Collector
Is hung off shelf and only thing touching
the floor is seperator can. Seems Awesome. I would like to add a wynn filter at some
point when I have $$$$. (I can’t see how
any more air could flow through this thing,
At the farthest blast gate it feels like it would
pull my arm off if I stick it to close.) Debating between .5 canister / Bag,
Don’t really need anymore suction. Anyone with a measurement of the
height of a Wynn canister it would be
greatly appreciated. Thanks,Andy

The website has the sizes for the different filters available:

I also recommend you look at the 35A tab for installation instructions on your HF DC.

For the HF DC teh 35A is the correct model. I personally use the Spun Bond poly…

I like it. Where’d you get the baffle and the separator can?

Thanks for all the help. I made the baffle and the can is a salt tank for a water softener.
(33” tall x 18” w /no taper) seems good.
I just wrap a round of tape to seal lid Andy

Your lungs will appreciate the Wynn cannister. Get it as soon as possible.

I measured my 35A cannister for ya. It is about 24 inches tall.

I set it up so there’s only 1/8” clearance between
the two fittings and found a heavy duty,
3” wide rubber band that fits connection perfectly Also repurposed handle off DC and
Put on seperator ( can already had two holes
In perfect spot that needed plugged anyway!

Threw a couple chains in the old handle holes
and fastened to joist. (I wish basement shower wasn’t
in way, but it’s a necessity ) Thanks for all the help and glad
I got some comments so I can learn how to work this site.

Smart looking setup. It should serve you very well.

The Wynn filter is more about trapping the super fine 1 micron stuff, than it is airflow. It’s this invisible small dust that goes right through the bag and into your lungs.
