Blast Cabinet and Compressor Inquiry

[nitroracer20]

Morning

I acquired ablast cabinet this weekend along with a skat blast dust collector. The gentleman also has a compressor I'm thinking about buying.

Does anyone have any info on these Brunner compressors? I heard they are no longer in business. It was shoe horned into a corner so I couldn't get too many pictures. I believe its 80 gallons. Runs well. Do you think this would provide enough CFM for mostly consistent blasting? Motor specs and compressor casting stamps also attached, if they help. The pump is massive compared to most that I have seen - would this help in maintaining high CFM?

I paid $100 for the blast cabinet and dust collector. He wants $100 for the compressor.

Thank you. Looking forward to using this setup soon!

Anytime someone is giving valuable things away for pretty much free that are not stolen I get everything they have.

Wow nice score. A hundred busks for the compressor is a great deal. Jump on it.

I can't identify the specific compressor/pump model, but based on the size, age, and the motor, you're probably looking at a 15 - 20 CFM setup assuming the pump is functioning normally (no valve issues, etc.)

Will that run your Skat cabinet? I'm sure it will. But how "constantly" will depend on the the setup. Different guns have different air requirements and even for a given gun, you can run different jet/nozzle combos that will increase or decrease the air required.

For example, Skat's own jet/nozzle combos come in small, medium, and large with 4-8, 10-15, and 20 - 25 cfm air requirements respectively. If you get everything hooked up and dialed in and you find the compressor can't maintain pressure for the type of blasting you're doing, try a size smaller jet/tip. The trade off is that the smaller combo you run, the less material you can remove at a time. You'll still get the job done, it'll just take longer.

Lol. Joking, right?

Heck of a score

If it was near me I'd have jumped on that deal already.
Pay him quickly before he changes his mind

The only question is whether you have a 230 volt, 30 amp circuit to power it. If it runs, though, I'd buy it anyhow. For $100, you could sell it on for a profit, either way. That's incredibly cheap for a compressor that size.

 

[nitroracer20]

Phew. Okay Ill grab it! Didn't have enough room in the truck. Its all part of an estate cleanout from my FIL's friends father. Tons of great stuff for cheap.

This is an A414 pump.

 

[MacMcMacmac]

Looks like it was built in 1971 or so. You are possibly dealing with a 50+yr old tank. Give it a good once over.

 

[nitroracer20]

Mac - thanks for that helpful info on the pump! Can you PM me that manual, if its pertinent to my application?

Pump has good oil level. Tank itself is pretty robust. Not like the tin metal **** in many modern compressors. But that was my first concern (pin hole leaks). When i go to pick up ill pressure test it for a little bit first. Drain valve was open when i went there.

 

[nitroracer20]

Some stuff i got with blast cabinet… Also got some black beauty media. He has another 5+ 5 gallon buckets of media i can grab. Should i be concerned about moisture content on the old media? Is it trash?

Suckage OP. I have been looking for a deal like that. As mentioned you may want to replace that tank and clean everything else up and you should have a great set up…

 

[nitroracer20]

Compressor secured! Heads heavier than tank. Holds good pressure no leaks.

You **** + nice score!

Hello again,

Compressors working well.

I wanted to change the oil.

Does anyone have a recommendation for oil?

Thank you for your time!

 

[Speed-Racer]

That is quiet the bargain you found. Would go back if anything else remotely interests you.

Most compressors use 30w non detergent oil . Non Detergent, so any junk drops to the bottom. Need to check your manual if synthetic or conventional and if they list a oil weight.

 

[nitroracer20]

I ended up ordering a 30 wt conventional non detergent. Saw someone recommended running 20wt hydraulic for these Brunner pumps. Also seen some people saying their compressors struggled with 30 wt on cold days.

It Should be here today, ill report back once I swap. Hopefully im just overthinking a simple fluid change.

Attached a cut sheet from Brunner for oil recommendations - if it helps someone.

 

[Jswain]

Some compressors will trip the breaker depending on how it's sized using conventional oil when it's cold.

I use amsoil sae30/40 synthetic, my old compressor wouldn't start up in extreme cold until I switched to it
