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

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

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

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.

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 😂

This valve was easy to assemble and fit to the lid of my dust collection drum. Valve gives assurance that drum won't collapse under vacuum. Would recommend 👍

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

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.

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.

ممتاز جدا جدا

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.

als Unterdrucksicherung, funktioniert prima

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