Big Blaster Cabinet Exhaust Help

[Guest]

Hi Guys,
I could look forever and find a lot of info and might take forever also

My Big Blue as I call it is like 4x4x7 upright. It was designed after one that one of our members had built and I have not ask him how it did with his set up on the exhaust that he has and he has not been on in a long time?? And I don't think he can coat any more where he had to move to? It works well but as the black beauty get used over and over it get a little dusty in it. It gets fresh air from the top left and right and that's it. I can seal if need be.

I know the picture of it is posted either here or EW but can't find the dag thing

Any way. It is outside not inside. That is a lot of space to clear dust out. I know that some of you have some big ones so thought I would ask to see what you use to keep the dust down. I can take a picture and post it Sunday so you will see where its located and that might help also?

Mine is on this design but taller. But don't build one if you like the design till you get with me. It has a big draw back that has to be corrected to fit the persons build and I screwed up and build the door to his spec and he be a lot wider at the shoulders than the average guy.

Re: Big Blaster Cabinet Exhaust Help

You could two of their blasters in my cabinet. Even the one I have from Harbor Freight that works great in a normal cabinet I would need 3 or 4 and not sure if that would do it? The only other way is to design it like I have my paint bay and I designed it to be a pressure bay. When I seal it up and cut the one blower on the bay like bulges and the only way any thing can come in is through the blower through the filter. All else goes out the 12" exhaust or any cracks. And you can see what is not sealed by the paint color that is around that area. One thing about my design is that no paint ever gets to you blower motor and if I had to and I don't I could have filters out the 12" exhaust to capture the paint. It also work OK for my powder coating as well. But paint is more in fumes and not as heavy as paint in my bay so even though you can blow on it with you own breath it does not all go out the port.
At least If I build it like that I want have to worry about any media taking out the blower motor for sure? I will just have to get an exhaust hose maybe 30' to dump into something or just dump into the air and dirt?

Hey Al do you think I have answered my own dag question to my looking for an answer??????

Re: Big Blaster Cabinet Exhaust Help

I was thinking about building a cyclone collector until I found this item...

http://www.cgallery.com/jpthien/cy.htm

I made one of these up. It works pretty good with larger chunks but I haven't completely conquered the fine dust from Aluminum Oxide. I am going to turn my air pressure down to drop the particles out of suspension a little quicker. Also, I am right handed and I have the exhaust on the upper left side of the cabinet. I may be blowing blast media directly at the exhaust. I may move it to the upper right or put a baffle in front of the exhaust.

Re: Big Blaster Cabinet Exhaust Help

That looks to work good and I saved that link. But I have to have something bigger than the norm to clear my dust. The cabinet I built does right well and I can see OK I guess but as normal when doing big parts you have to look to see if you have missed something and that is when I need the dust to go away so I can open the door and look a little sooner. I just open the door and hold my breath or walk away for a few. I really think if I build this one using a fan blowing in with a side exhaust it will work fine. I have to displace 112 cu feet of space and the average blast cabinet is like 18 + or - so I have a lot of space to clean out for sure. If I am going to build it as pressure feed thin I have to fig where to put the blower say on the left and then where to put the exhaust on the right? The blower would I think not care where its at but the exhaust would be the key to get the most dust out but leave usable media by it falling to the bottom. So I guess I need an 8" to 12" fan that was 3 speed or variable or use a dimmer so I can set it any way I want and then fig what size exhaust port I need? 4" would be a good start I guess? With a set up like this you could have a trash can with maybe water in it and a baffle to catch all the dust and its exhaust would be just for breathing. And the main thing you would not have any dag noise like using a vac This could work on any type blasting cabinet of any size as long as you get your blower sized correct and your exhaust port right.

Well as soon as this weather fig out what it going to do and when I guess I have a new project in store for me. Sounds like fun to me! I like a new challenge! You know being older than dirt you know

I hope all the Lookers and don't say nothing guys keep and EYE on this out come because it just might make your space a very quite space

Re: Big Blaster Cabinet Exhaust Help

almost. They have a cabinet the size or a little bigger that what you have. You need a fan and motor that can move a lot of cfm. Mark from the metalcraft class has a big one and he told the class if you ever get a blaster the first thing to check is to make sure when you turn it on is if your rubber gloves dont rise upward without your hands in you might as well get rid of it. I must of misunderstood what you wanted. I thought this is what you was looking for Here is the link of the fan http://littleblaster-store.stores.yahoo ... lades.html they also sell the motor also.

Re: Big Blaster Cabinet Exhaust Help

I remember some guys on the EW forum having trouble keeping media in their cabinets because they had to much shop vac hooked to it and one even said it would pull his gloves out of the unit. I also had trouble with mine because it had more pull and the inlet was to restricted. I could look down at the bottom and see the media trying to go down the tube for recapture bubbling and I said this is not going to work. So I took off the baffle cover and then I started enlarging the small 1/8" holes like playing unconnect the dots until I stopped the bubbling and then all worked fine. Now what you said about what the instructor said the cabinet should do with your gloves would only work if your excess reusable media just fell to the bottom for you to scoop up latter and reuse. That is the way my big one is. No drain at the bottom. With a normal blaster you have a hole at the bottom on most of them for the media to go back into the same media supply or either just into a pail for later use. It almost sounds like his thinking would exhaust reusable media and that is not cost effective? All you want to do is remove the floating dust so you can see better and when you stop you can open the door then and not have to wait like I do with my big one right now. When I first fired mine up with new bk beauty media I had very little dust until I started reusing it and of course with out any exhaust I get more and more dust of course. Now if I would use a new bag in the tank and keep it new all the time and throw away the media on the bottom I would have very little dust and I would also go broke buying media
So I would like to see his design or picture on a cabinet and the location of his inlet and outlet placement so it would save reusable media that is if that is what he wants with his design for it to exhaust dust and save media? I would also like to see a set up say using the motors and fan blades that you linked me to? The Blades look like pullers an not pushers and I guess the motors or completely sealed I guess? I will try to do some more looking on the net to see what I can find to help me make up my mind as to what I need I guess?

Re: Big Blaster Cabinet Exhaust Help

His had a reclaimer and was able use a small amount of media and just keep recycling it. It I thought about making one but after I seen his work and the small amount of media it took. I might just save and wait and get one like that. I cant do the kind of blasting I need to do until I get a compressor anyway. I could make one now, and I have a nice pot blaster. I just dont have a big enough compressor. Hell I cant even get a good smooth coat on a part.
I sure you will figure it out.

Re: Big Blaster Cabinet Exhaust Help

Hell just move out of Al and move here and we blast and powder the east coast????????????!!!!!!

Now what I want to know is where the Hell all the rest of the advice is on this forum? Damn I wish TNC (Todd) was up full speed he said he was going to where the experts were? And there are some that are good but I think we need to get some more expert members in on our forum to live up to his expectations! For sure we have gained some great guys with a lot of info but if we want to be #1 we need more experts!
What you think
Have a good one and thanks for all your help and links And once I fig out what it will take to do the job that i need I will let you know the findings by PM.
