Yes. Tape all joints with UL Listed Foil Vent Tape.

Can I use it for dryer vent?

Asked by Mario July 21, 2020

Answers

Absolutely! In fact it is much safer to use as a dryer vent than those collapsible tubes, which can be a fire hazard. Just be sure to have some tin snips on hand to cut down to size :)

Yes, with a slab floor, this is the only way to do it. Make sure you size the pipe correctly and balance the system when you are finished.

Can this product be used for a vacuum system in a wood working shop?

Yes, strong enough but you may need to seal the joint

can this be used for a dust collection system of 1400 CFM?

Asked by Robert April 30, 2019
6
Answers

This product can be used for dust collection systems, but that is a lot of air to move through a 5 inch diameter duct. Most likely, the throughput of the system would be significantly reduced. For an efficient transfer of 1400 CFM (which is almost a cubic yard per second), I might suggest using 8 inch duct (SKU# 148695) for the main runs and short segments of 5 inch for the drops to the tools. This way, the negative pressure differential at each tool will be enough to evacuate the swarf, but still have enough flow through the main lines to service several tools simultaneously. Depending on the number of drops, you might need to damper some ports to keep the flow velocity high enough in the main line. Some experimentation should allow you to get a feel for it.

Sorry for the late reply, but here's my take. VTR (Vent through Roof) should in my opinion be avoided whenever possible. The pipes commonly are clamped rather than screwed. Depending on location and code it may require it. Duct tape would be hard no. Perhaps a metallic aluminum tape may be used. Again code would dictate. This line shouldn't condensate enough to bother. If you do insist on insulating in some way a common 4' fiber based white insulation wrap may be used.

Can i use this for airconditioning ducts under a house

Asked by Tim January 11, 2019

Answers

yes BUT -- The larger diameter pipes 6", 8" 10" and 12" will handle greater airflow at a lower velocity. This pipe has seams where there is potential for air leaks. Apply a sealant to cover this seam. When you assemble the pipe make sure the ends are not opposed to the air flow, Seal the joints with a 4" wide duct tape or similar long lasting adhesive tape. (Metal air Duct Tape). . INSULATE! Unless you are planning on heating or cooling the crawl space. Insulating this pipe "for a crawl space" is a multiwrap task. Begin with Wrapping the pipe with overlapped spiral of a quality plastic. (Tight wrap with decent overlap.) Next spiral wrap at least 1" insulation around the pipe. Not too tight. Last, wrap over the insulation with a real good cover wrap of heavy plastic. Critters like to be warm in the winter too! Try not to compress the insulation, or it won't insulate. If you can use a thicker insulation do cover pipe than the 1" insulation. Flex duct comes insulated in a similar fashion, but flex duct is more restrictive to airflow. (The inside isn't as smooth as straight metal pipe.) I only use flex duct for air take off's from a trunk duct line to a baffle or air box for a register. (Short lengths.) Be sure to use some pipe hangar material to suspend your duct work off the ground. Use good clamps to connect the duct. No fun if the fittings fall off in winter! Metal fittings to an air box or baffle. Metal fittings are great, but thermal expansion will generate "Creeks and groans" in the air distribution system. Metal to metal connections will bring these noises into the living area. Use a short section of flex duct to join the "trunk" or extension duct to the air baffle to reduce the noises. Economy versus cost. It will cost more to buy all the materials and the labor you put in to create a crawl space duct. More expensive in the short run. Over time, the extra insulation and more efficient airflow will save some money, and possibly improved comfort Unfortunately nobody will see your good work because it's in a crawl space! But YOU will know it's there, and done right.

Is it okay to use this right from the back of the dryer (not inside of wall). Thank you

The county inspector here in Upstate South Carolina told me code states it must be 28 gauge for a dryer vent. This is 30 gauge. So, I need to replace this. And of course, Home Depot doesn't have 28 gauge in stock, and that I'll likely have to go to an HVAC supply house.

This pipe is easy to put together and cut to length as needed. I used this in my attic space to replace a dryer hose that had been used for a bathroom ceiling vent. dramatically cut down on the vent noise and increased the air volume of the vent.

It is a little hard to work with; some pieces fit together easier than others to make the cylinder. Connections can be a little tricky too, once you tape it up though it works just fine.

Great for relocating dryer vent.
The 5 ft. sections are nice when you have to run a long distance and need a rigid vent. I used this on a recently acquired rental house that someone had relocated the dryer connection on, but did not run a new vent.
