Can I turn a dust collector over?
4/21
I have a small closet I keep my dust collector in and need to upgrade, but don't have the room to spare - I'm wondering if I can mount the base of a dust collector to the ceiling (reinforcing both the ceiling and dust collector as needed) and run it upside down. Will this harm a motor or fan on a 3hp double bag grizzly type dust collector?

Mike, cloud you not hang the collector, right side up, from the ceiling with support wires or cables?

No, the ceiling height in the closet is less than 8' - all my ducts running to the closet are right above the floor or coming out of it - I couldn't efficiently run the duct with it on the gound, or even at all probably because the inlets are close to the ground on the new DC. It's pretty cramped in there with the single bag 1.5HP DC I have now (what the closet was built around); but if I turn it upside down then the inlets are close to the ceiling, I have plenty room for the drops to run down to the ducts. I was hoping all I would have to do is swap the filter and collection bags around so the filter is on the top when it's upside down. I wasn't sure if larger motors are designed with gravity in mind holding anything in place, or if the fan might be negatively affected by the change in position. I guess if no one really knows we'll find out in due time, I'm expecting the new DC delivery today.

I have a powermatic, collection on bottom and vent bags on top. Having looked at the impellers and the way it is designed, seems to me you should be able to run it upside down. The only thing may be the spin or rotation of the impeller pushing the dust a certain way, but I'm believing not. I bet gravity has more to do with the flow of things versus the other design factors. Try it and let us know your results.

The electric motor and fan do know or care weather they're upside down or not. The motor bearings are sealed and there's no bottom oil pan or anything like that. On the two bag DC, the central metal hopper will not work inverted but just mounting the motor and fan to the ceiling should make no difference.

I mounted a 2 hp dc to my wall about 8' off the floor and it worked fine for several years in that position. I agree with the previous posts, a dust collector is just a motor and fan and doesn't care how it's mounted,....as long as it's mounted securely!
You could also re-configure it so your motor is inside the closet with the filter bag outside, allowing you to go to a bigger filter bag which also helps greatly to improve performance.
good luck,

Well it's done. And it works great compared to my old 1-1/2HP, I can tell by it picking up more chips but also the ridiculous whistling coming from some of the machines. It was a good deal to, 3HP for a little over $500 shipped. I think the only improvement for the future will be extending the discharge from the fan about 12" lower so the collection bags will sit on the ground and I can fit bigger filter bags in when the time comes.

Nicely done but...
Band-saw dust (for example) is heavy and I think would pull the bags down off the unit or eventually rip them?
Why not put a base with caster wheels back under the bags so you can easily haul them out to the dumpster?
I also hope your air compressor has a good filter on it since it's located right in your dust collection closet?

The closet was built perfectly sized for the old DC and air compressor. At the time it was built they were seldom used so I build a closet around them to make storage above and keep the noise down when I did use them. The dust and compressor have never been a problem, and if I need to I can just duct the intake to outside the the closet.
When I extend the discharge duct the bags will sit on the ground, I've toyed around with the idea of a base or wheels, but if I do something temporary it will probably end up being there way to long, so for the in between time I plan on making frequent bag dumps, this will hopefully motivate me to fix it sooner than later.
For now I am happy with the results, but I will be sure to post pictures if anything does go wrong...knock on wood.

Nice work. I thought you were crazy but the picture explains it all. I assume you did not just swap the bags, but actually rotated the assembly. My bag flange thing has a funnel on the inside that I assume needs to point down.
I really like the idea.

FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)
WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
A valid email return address must be included with each message.
Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
Subject lines may be edited for length and clarity.
"Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
