Topic tags/keywords: dust collector

I bought a Delta 50-720 1 HP Dust Collector 650 CFM recently and assembled it together and turned it on. It is so loud that it feels like a jet engine taking off right in my garage. Worse than a regular shop vac. I am wondering if the motor can be shielded for noise (if that is the source of noise). If anyone has any ideas on DC noise control, I would love to hear about it.

That doesn’t sound right to me. I put on ear muffs when I run the shopvac but not the dust collector.

If you have the room you might do Like I did, and make a small room in the corner of the shop.

Check and make sure you put the impeller on correctly. If its facing the wrong way it will be noisy

Gary – I do the usual safety things – ear muffs, goggles. My concern is really for others in the family and neighbors who are like 12 feet away. I might look into building an enclosure similar to yours.

Marc, I will double check but the impeller was mounted correctly.

Mine had a fair amount of noise also but probably not as bad as yours. If the ‘suck’ is good the impeller isn’t on backwards. Could be some of the packaging came loose and is stuck in the impeller, that would cause a lot of noise and probably some vibration.
I built a small enclosure outside and ran the tube through the wall, easy to just drill a 4 inch hole with a circle cutter. Another small hole would get the electricity outside and a remote control is almost a requirement for these whether inside or out.
That made it easir on the ears, freed up shopspace, and makes emptying it a more dust free experience.

if you don’t have a hose attached, it will be quite throaty

Well, I had the hose attached at one end to the DC but the other end was free. I would like to connect it to my table saw as a test, but don’t have the necessary ducts on hand yet.

Many of you have done something to contain the noise and it may just be that dust collectors are very noisy. I seem to have everything installed correctly and it sucks well! So, stupid user errors can be ruled out.

I think I will deal with this by building a somewhat soundproof enclosure. Thanks for all your comments and suggestions.
