Description

I wanted to clean my dryer vent, and heating ducts in my house.

This screws right into the 1/4" male NPT end of an air hose, pulls it self along the vent, blowing debris back toward you.

Here is the design for the forward facing version

Saved me $300! That's what I was quoted from the pros for a 30 foot second story duct with 8 years of lint. Similar nozzles cost $60-160. Operating Tips: -Work outside in. I removed the exterior flap/cover. -Measure how far the run is to the dryer and mark that on the hose. -Set dryer to Air Dry no heat to clear the dust as you go. -Use back and forth motion as it pulls itself into the ducting. It doesn't rotate on its own so twist the hose several turns each direction as you go. -Bends in the ducting may require more back and forth and more aggressive twisting. -Once I got to my hose mark, I went in and disconnected the dryer and it had made it all the way. -Did the full length 3x. Settings: Set 120 PSI, which gives 90 PSI working pressure with the valve open. My small compressor only supplied this for 1 min then I would wait for it to fill. Ball valve is 1/4" NPT. Skip heavy quick connects, I attached nozzle directly to a 1/4" Flexzilla hose which worked great. Bambu PLA Basic.

0.2mm layer, 6 walls, 25% infill, but where can I find the adapter to connect the valve to the hose

Worst case, how can I create these threads in Fusion 360, and is it possible to get NPT thread references

Looks like an interesting idea. Does it do a bit of a wild dance down the ductwork?

Unfortunately it does not whip or spin. just launches high pressure air back. I used it to clean the ducts in my house and, more importantly, the dryer vent along with a shop vac to suck up the junk.

Very clean print. Can't wait to try it out this weekend!

@CHCustoms

Let us know how it goes! I need to try this myself, but will wait to hear back on your success.

Hello everyone, I haven't printed it BUT I've had an identical stainless steel one for 5 years and it works very well what you need to know is to measure approximately the length of your dryer hose, mark the correct distance on your air hose with electrical tape, then insert the air hose from outside the house to the correct length, then activate your compressor to send air, then pull the hose a few inches outwards, then pull again (you can also push the hose back in a little) and so on (NB if you have a leaf blower, I disconnect and remove the dryer from the room and I attach the leaf blower (to the dryer outlet connection (dryer..) with strong tape to help push debris from the dryer hose out to the outside
