no previous part Part 1 of Air Quality series Part 2: Harbor Freight DC with Super Dust Deputy modifications: Parts List »

Started build today with parts I’ve collected so far.

• Attached 6” flange to HD Rubbermaid Trash Can lid and cutout hole
• Sized ducting to Super Dust Deputy –missing 5”-6” and 6”-4” adapters
• Loose fit output port components ( 5”-6” adapter, 6” 90 elbow, and another 6” flange to connect filter support shelf (to be cut to size)

The Harbor Freight blower will attach directly to the SDD via 6” connector and 5”-6” adapter supported by closet wall. The SDD will be bolted to a supporting shelf and a flange below to connect via 6” flex tubing to the trash can mounted on a dolly.

Considering making closet double wall with baffles to reduce noise (saw a similar approach to enclosing compressors to reduce noise a few years ago)



Orientation of blower to be bolted to supporting walls in to be built closet. Should work equally well on a mobile cart setup.

The output port will be connected to a .5 micron filter from Wynn Environmental and have a Gamma Lid collection bucket from Home Depot per Dick Wynn’s suggestion. Expect this system will come in less than $600 for a 2HP Cyclone DC. Not bad! If I need more HP to drive the planned shop ducting, since its modular I can R&R the HF Blower without too much trouble :-)

Very Nice.

Just completed something very similar.

Key points of difference:
1) Blower output remained rectangular. Built a 24” radius curved section to feed the filter. From memory, recall that it is a 6×4” tube.
2) Built a “collet” to direct connect the output of the SDD to the blower input. Required cutting out the HF input port/flange (was able to reuse that piece as the connection port to the collection bucket,

Note these two changes made the solution viable without any piping. Intent was to obtain highest flow rate with minimal resistance.

3) Built vibration isolation system. Used a rubber hose cut to 1” lengths to isolate the blower on all three sides (bolt head to flange, flange to support, and support to nut). Works like a champ. No vibration. Very little noise (have not measured yet). Conversation quiet. Can still hear the background music.

Here is a almost done picture showing the above.

As for performance. Measured at the input to the SDD (5” port) was reading about 5,000 F/M. Have a 5” by 25’ flexible hose. Had no problems in cleaning up the the shop when done. Need to put it through the paces to see if it was worth it.

Have your say...
