DUST COMMANDER DUST-SP Anti-Crushing Valve for Plastic Barrel / Cyclonic Filter

excellent little item = fitted to my collection barrel on my dust vacuum unit. Works wonderfully

The media could not be loaded. Awesome bit of kit, used it on a barrel to make a homemade dust collector system and to stop it exploding if the hose ever gets clogged up.Works brilliant and seems like it will last for a while as the parts despite being plastic are good quality. Really cheap too considering the cost of me replacing the barrel and parts.The instructions to get everything fitted is an ingenious idea by turning the box for the product into the instructions when you unfold it see video for this

Having had my waste barrel collapse due to the vacuum this is a nice little device that prevents the barrel collapsing again.Simple to fit and use though could do with a cover to mechanically protect it.

A capable relief valve that works. It arrived on time and in good condition. It has been installed and it performes very well. A good purchaase.

Works as expected. Simple to fit.

Great little device. It is small enough not to get in the way and does what it is supposed to do. It has stopped the crushing of my barrel that I have as a dust collector for my mitre saw. My shop vac is a little bit too powerful for my mitre saw. Great buy

It works as advertised but the gap that opens is not letting in enough air to stop the vacuum trying to crush my plastic bucket. I may need to buy another.

Well worth it to remove the risk of implosion. Easy to install.
