Venting cyclone outdoors--vent cover?

[John Stevens]

I'm in the planning stage of a ducting run to vent a cyclone through the wall of my basement woodshop. The only detail I haven't covered is the end of the duct.

I vent the exhaust from my clothes dryer, and the end of that duct has a nice, neat cover with a grate to keep squirrels and other rodents ( :eek: ) from coming inside. Does anyone here know where I can get a similar cover and grate for a six-inch 24 gauge steel duct?

Regards,

John

Heres how I did mine, 8" pvc though. Cut the screen to fit inside the coupling and tapped it on, no glue, it can be removed with patience and a hammer.

I would just do a 45 degree downturn to keep out the rain and cover the end with some 1/2" hardware cloth screen.

Hi John,
Do you have any problems with rain water blowing into the vent?

I'm in the same planning stage as you, John. If you google "6 inch wall cap" you'll find a number of different options. I'm trying to figure out which of the cap options would be the least noisy. Let me know what you decide on.

I may just be lucky, but mine just has a 45* bend down, and that (alone) has worked fine.

Just imagine if a squirrel or ?? crawled up that pipe and was relaxing when the cyclone got turned on..............................

That squirrel would learn real quickly that crawling into the pipe wasn't a good idea! I have my cyclone exhausting through insulated HVAC flex to a shop-built square-to-round that fits ito a standard concrete block vent exiting my crawl space. It already has a screen.

I like this idea, but I'm going to use it in the 45 downturn.
I will just use a 1" ring of pipe to hold it in the outer end of the 45.
Thanks for sharing!

The traditional way is to cut the pipe at a 45 degree angle (a 45 miter) with the open side facing down. Then install the screen on the face or back in the duct a little ways like Ed did it.

Why do visions of a "squirrel gun", an offshoot of the "potato gun" come to mind?? Hmm...

[john taliaferro]

I vent outside this time of year in a rural area , but cap it when heating or cooling . I pick up some flow when open . Squirrel gun was funny.

Whatever the mesh the more open area the better to minimise pressure drop. Best re. rain water to slope the duct downwards a bit towards the outlet - that way it'll drain....

A 45 or 90 would be good too to keep out wind-driven rain.

[Jim O'Dell]

If you use 6" exhaust this is what I used. 244469 This replaced the 90 degree transition on my Clear Vue to straight, then there is a metal 8-6-6 wye going to two pieces of flex hose to dampen vibrations. The flex hose hooks to these: 244470 These are 6" vents, just like 4" dryer vents. I got these at Lowes. There is a plastic grid behind the louvers that keeps critters out. Ants and such can still get it, but I haven't seen any. Jim.
