Clemco Easy Load System And Closed Circuit Blasting System


hello, im Aron and I recently found and bought an older clemco easy load system and closed circuit blasting system. Has anyone been around one of these or have one? I have been looking for information on these and haven't found much about them. It has a 2452 6cf blast pot with the 6cf storage hopper on to of it with a 55 gallon collection container and a water filter. It has the big clemco air deadman valves that are like a semi truck brake chamber. Do they make parts for these?

The compressor i have is a sullair 650 cfm at 175psi which i do not think is big anuff to run the closed circuit blasting system.

Thanks for the advise

What exactly is this closed circuit thing? Does it collect the media and reload it back in to it's self? 650 cfm is a friggin monster compressor. How could it still not be big enough for anything.

Re: Clemco Easy Load System And Closed Circuit Blasting System


I will try to get some pictures of it soon.
If you look at optaminerals.com under clemco go to special application equipment and you can find the specs of this system it wont let me post a link to it
Closed circuit blasting uses a tool that has a brush and wheels on it that attaches to the end of the nozzle and has a vacuum line hook to it sucks the media back up to the storage hopper to be used again. This is only ideal for large flat surfaces. According to the specs the vacuum system will take 290cfm so that leaves me to run a 5 or 6 nozzle. I was hoping to be able to run a 1/2" nozzle but it seems like that would take 800-900cfm.

Re: Clemco Easy Load System And Closed Circuit Blasting System


If the vacuum takes 290 CFM to operate The that would leave you with 360 CFM to blast with. If you do not go over 150' of 1 1/4" blast hose you could run at least a #7 "7/16"" Blast nozzle effectively. You could run a #8 "1/2" Blast nozzle but you would be pushing it. It also depends on how much wear your 650 CFM compressor has as well. Those units are fairly old and even with 750 CFM or more of air, they were not productive. You would want to run a re-usable media such as Garnet, or Steel Grit also. Stay away from Coal Slag, Silica Sand and Crushed Glass, etc. Those units are pretty out dated and the parts are probably pretty pricey to boot.

Man! I had almost forgotten about those beasts! Schmidt did their version as a BRS ("Blast/Recover Systems). Some of those parts could be used as substitutes if all else fail.
The venturi vacuums on those machines were notorious compressed air hogs, I sure Painter has it right with something around 300 CFM air consumption when new, so you have more than enough air with a 650. You do want to check out the orifice and injector of the vacuum to make sure they are not too worn. They air consumption goes up fast as they wear.
The guy who would have the best access to info in this group would be Nate Bjornson (nbjornson), who works for Clemco. If you can’t find a way to contact him, you can look at the last blast light thread I responded to and find his input there.

I think IPEC used to make a simular system.
The Navy contractor I used to work for was pulling them apart and using the vac systems. I think because the blast tanks could not get recertified or something like that.

they were old units, but some still worked good.
The Company would blast only or vac only never ran them together at the same time. even though they had tons of air psi. I think it just didn't work right??

Re: Clemco Easy Load System And Closed Circuit Blasting System


Hello Aron,

First, please allow me to say thank you to RAM416 to dropping my name on this issue. I have not been on here for quite some time as I have been very busy. I always try to look for posts associated with Clemco equipment since I am a Territory Manager for the company. There are alot of good comments here and some that should be clarified and corrected if you will.

This system is not "outdated" first off. It is still sold and used widely today in the industry, but it is application specific. It appears to be set up for recycleable abrasive since it has a storage hopper above the blast machine. I cannot see the metering valves mounted underneath but by the way you describe it may have the PVR pinch valves installed. Now the unit you have here also is from our Aerolyte product line which is for light weight abrasive. Primarily for aircraft stripping for use with plastic, wheat starch or corn starch media. It has a 60 degree conical cone that is epoxy lined at the bottom instead of 35 degrees inverted by industry standards. It does consume 290 cfm from the factory for the vacuum plus the nozzle size plus 20-25 cfm for the helmet you are using. However, since this is an Aerolyte designed for light weight media it may very well be set up for 150 cfm at the vacuum. We do have Owners Manuals for these available through customer service and through our web site and parts are still in stock and mfg today. The wet filter installed with it was primarily designed for light use vs. more Industrial use that would be used with the optional Reverse Pulse Dust Collector that we sell.

Let me know how I can be of further help to you. Good luck!

Best Regards,
Nathan Bjornson
