Flex hose for dust collection--- durability gone downhill?11/6
I'm not sure if the material quality has gone downhill or if our sheer volume of dust (business/production) has increased enough that we're just wearing stuff out, but we are replacing our flex hoses a lot more than we used to.
I have hoses attached to tablesaws (ripping plywood and 4/4 lumber) that get only a couple hours of use each day, and after 6 months there are holes worn through the webbing between the wire ribs....... and it's not because of sharp turns (we don't bend our flex hose like that). I don't think it's because of excessive flow/force either because this particular saw has somewhat less airflow than I used to have on it. And this saw rarely gets any melamine or laminate cut (ie, particles aren't harsh abrasives).
Same thing on our CNC. The table is only a 4X8, and the flex hose going from the dust header to the spindle is 6" hose. We used to get YEARS out of that piece, now we maybe get a few months before it's cracked and split.
I've been buying from places that sell dust collector equipment, like Oneida, and I'm pretty sure most of it is PVC.
Should I be looking into polyurethane hose instead? I'm just shocked at the price I see on polyurethane hose, it's not uncommon to see $200-300 for a 25ft length of 4" duct.
Spend the money on the better hose, I use Air Handling Systems. I've tried using lesser dollar stuff and it never works. Once you figure out the labor time alone in replacing it every few months, the better stuff would have already paid for itself.
If a machine is stationary, use rigid pipe to make your connections. No need for the flex if the machine is not moving.
We do run rigid tubing where feasible, most of the machinery here has it.
Dustin, I'll check out Air Handling Systems, thanks!
I'm not production but run a fair bit of material through my system. I bought my hoses, (as well as most of my pipe), from dustpipe.com. I think they're probably polyurethane, though wouldn't swear to it. Anyway they're over a decade old now and no holes or signs of wear at all, just a bit of yellowing.
Now the hose the connects my Torit cyclone to the barrel is another thing altogether. I've replaced that thing twice in the last 8 years or so. Going to have to switch to something different next time. Not sure what Torit uses.... but it's garbage and won't be buying another one from them.
