I purchased the Delta 50-720CT a couple weeks ago. So far it has been working great, and handles everything I have been using. I roll it around and attach it to one tool at a time using Rocklers Dust Right system, which I strongly recommend if you are doing the same. Anyways, the noise doesn’t seem to be too terrible outside of my garage, but inside is a different story. My garage has insulated walls covered with 1/4” hardboard on the bottom half and 1/4” pegboard on the top half of the walls. The ceiling is insulated as well and is covered with 5/8? drywall. The floor is concrete and my walls are covered in shelves with boxes and tools (woodworking and garden). The garage door is solid wood 1” thick I believe, maybe a little more.
I do wear ear protection, but still this thing sounds louder than my 12gal shop vac did in here(although at a lower frequency). I would love to lay down duct work and get a bigger dust collector that could sit in a closet covered in sound dampening material, but that isn’t going to happen for a long time. So in the mean time I have to roll it around, although not very far. Anyways, I was thinking of possible ways to dampen the noise for my own sanity. Since this is my first dust collector though I’m not too familiar with its noise properties. The enclosure is metal, and there is no ductwork that goes from the motor to the impeller, its just an open chute. I’m guessing most of the noise is either coming from the motor, impeller blades, or the cartridge(exhaust). What would be the best way to dampen the noise while still being able to roll it around and have it perform efficiently.
I was thinking of a closet on wheels with vents for air but I’m not sure if that would restrict CFm too much. If I make too few vents, it will get too hot in their and there won’t be enough airflow. If I make too many then the sound dampening wouldn’t be beneficial. Would a sound dampening foam lined box placed just over the motor with a few air vent slots work? Any suggestions would be great. Has anyone had experience sound dampening a portable dust collector?
