Glory hole blowers

My blower has announced that it is going to be dead soon. High pitch wailing is not a good thing. I use it for two glory holes. One is 20 x 30 with two large Giberson heads on it and the other is 16 x 24 with one large Giberson burner on it. I want to split these up to run on independent blowers. The blower that I use is this one:

It is over $1000! I thought that I could get two blowers at a much better price. These are the ones that I am thinking of:

They have more CFM, but not as much WCI. Would they still work for my application? I am running on natural gas.

Dudley probably knows how much water column inches his burners need, I bet if you give him a call he'd have an answer on that. I'm not sure the price of the expensive blowers is warranted, but my guess is the pricier ones are designed to run longer with continuous use, which I suppose is more of a consideration for a furnace blower. But that cheap one is so much cheaper that maybe you should get 2 or 3 of them to have as backups and then it's a non-issue.

I have a few eight inch paddle type blowers from Graingers I could let you have Mark. They will not be shy about producing the volume and WC you would need. I always used to cut them down with a big gate valve. Noisy. They're just lying around from the earlier days.

I use a variable trinity blower. Charlie Correll sells them. Dial it down to exactly how much pressure you need and viola! You are using just as much electricity as you can get away with.

Thanks for the offer Pete, but I think that noise is a factor too because they are in the same room as us behind the shields. We have lots of fans going and its hard enough to hear now....

I looked at that also.... can I run both GHs on it? How does it dial down? A valve? I have everything piped in for one blower on two GHs, so if that will work, I may just go that route. How loud is it?

Charlie's blowers are not quiet. I have one and it drives me out of the room. I am simply offering up a blower at zip for cost. It ran one of our big color melters for years. A real horse.

I mounted my blower in an electrical box and then added a few layers of mineral wool board to sound deaden it. Itís not that loud.

We have ours mounted in a box also, but the noise that it is making now is just too much. I'm wondering if it just needs a good cleaning and greasing...

Air Force Audiologists can tell what plan folks flew back when by what frequencies they have hearing loss at.

Mine is more credited to my time in the fire service with the big pumps. It was all before hearing protection was viewed as really important.

I really miss it.

My left ear has gotten noticeably worse the last couple of years. I know when the damage occurred. A certain rock concert about 40 years ago had me too close stage right. Bothered me since. Had my hearing checked by the blacksmith/fab shop I worked for in Seattle 20 years ago. Noted the loss in that ear. Not too bad, but now the tinnitus has gotten to the point that I can't ignore it when there's not enough ambient sound.

Get a hearing aid. Once the follicles start to die, the brain stops checking in and then getting the aid does you little good. There's a lot of very good hearing aids coming on the market that are a fraction of what ones like mine cost. You'll never get rid of the tinnitus.

Do you have a part number(s) for variable speed Busch blowers? On a quick Google search I could only find Busch vacuum pumps
