WORKSHOP Wet/Dry VacsVacuum Accessories WS25025A Muffler Diffuser Wet/Dry Shop Vacuum Attachment for Wet Dry Vacuum Cleaners, Fits Most 2-1/2-Inch Wet/Dry Vacuum Exhaust Ports

Buena compra y funcional

El dispositivo "muffler" asilenciador para la aspiradora queda exacto en mi aspiradora, y viene con un adaptador para entradas mas grandes.Lo unico que no me gusto es que realmente la disminucion del ruido es realmente poca, apenas se nota la diferencia con o sin el mofle

Lost the attachment that came with my shop vac and this is definitely needed and it works.

I’m so glad I came across this…I’ve been through so many shopvacs and never found a good solution to this problem until now! Cheap too!

I bought this for a small Shop Vac which has 2.25" / 58mm diameter intake & exhaust ports. With a 2.25" diameter vac you will not need the red tabbed 2.25" to 2.5" adapter to connect the diffuser. Models like the Rigid will need to use the adapter with the diffuser, and it will stick out further from the base. My model doesn't have a lip for the tab on the top of the diffuser to fit into, but the fit was snug and the tab didn't interfere with the connection. I'll probably make an indent for the tab using a multi-tool later if needed.I couldn't tell any difference in noise with or without the diffuser installed. I think that's why it's called a diffuser and not a muffler. I bought this to reduce exhausting dust back into the environment while vacuuming. I think it only does an OK job, but it's better than nothing and I don't regret the purchase.
