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

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.

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

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

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

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.

This little blighter is so strong on its lowest point, it deforms my solid and rigid blue grease bucket. Works a treat after I'd found a way of improving the opening of the inlet vent for less pressure. The pressure was only a big ol' Henry hoover but the system had no excess air to leak in. All of a sudden the combination of to much suction and close fittings where an issue 😂

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.

The media could not be loaded. Prefect little thing. Does exactly what it's meant too. Adjust per your needs. I used some sealant around mine as I ended up drilling the hole a little too big. Even though I have a steel bin, best to make life easy.
