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

Fitted this to my powerful vacuum dust extraction cylinder to prevent any blockage in my dust vac system collapsing the cylinder or collapsing vacuum pipes. Yesterday a hose got totally blocked by a piece of wood and sawdust. All I heard was a suction noise from this device sucking air into the vacuum cylinder to prevent any damage. I removed the blockage and all ready to go again. My advice would be to set the adjuster to kick in at as lower cut in level as possible prevent damage to any lighter vacuum hoses you may use. In summary: Easy to fit with simple instructions provided and well worth the money in my case so a very good investment. Highly recommended.

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

I was using this alongside the dust commander cyclone and this blue barrel https://amzn.eu/d/05NcqLeu, and a titan cheap vac from Screwfix. Out of the box I couldn't make it work with my setup, with the spring at its lowest tension the valve never released any air and the barrel would start to lose shape with a blockage I cut the spring in half, then was able to create the right level of tension to have it work. When it works, it's great.

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

Excellent work perfectly. Whish I had bought these years ago when I set up the cyclone collectors

Great little device, has saved me having to replace the collector when a blockage occurs and the collector (bucket) implodes.

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.

This works as it should. Cant say fairer than that.

Funciona correctamente, sin esta válvula el cubo de tu aspirador ciclónico se puede aplastar y colapsar. Puedes montar una válvula antiretorno de fontanería si la tienes, pero si no es regulable quizás el muelle haga poca fuerza. Mejor emplear esta válvula que es regulable con una tuerca con freno.

Gör sitt jobb.

Excellent device, worked like a charm, no more collpased buckets!

Schnelle und einfache Montage.
