Cheapie Mist Coolant Unit- think I can get it to work?
I bought this thing for around $10 shipped direct from China.
http://i.ebayimg.com/images/g/MYIAAO...zw/s-l1600.jpg http://www.ebay.de/itm/Nebel-Kuehlmi...72.m2749.l2649 I don't need mist for most stuff, so don't want to spend a lot on it, but it would be nice to have. I have a CNC router with a high speed spindle which holds endmills up to 6mm. So far I have only tested it with water. It won't siphon up the water at all unless I run the air at very high pressure. If I lift the reservoir above the nozzle then the water flows too freely, even with the air off. I've used mist coolant in the past. The unit I had years ago worked well enough that I never had to fuss with it, and so never learned anything about how it worked. The only thing I can think of now is to keep the reservoir high, but somehow restrict the flow. Any tips, or should I just toss the thing? Thanks, |

Thanks, ***************** Looks like a pretty typical air venturi vacuum sprayer. It will probably work. I found that if I didn't set the source tank close to or above the level of the sprayer it took a lot of air to prime and then you had to turn it down to run or you would spray all your liquid out in minutes. The problem with setting the tank up high is then it acts as a syphon and continues to drip for hours after the air has been turned off. Those may be ok for your application. Since I was automating on my CNC machines I opted for flood coolant with a centripetal pump. When the pump shuts off the liquid flows back to the tank that can set on the floor or down inside the cabinet below the machine. One thing to note is that a mist is not as good as micro droplet application and puts more coolant into the air. Most of the guys I know who are running "mist" are actually running a micro droplet system. Something like a Fog Buster, except there are some DIY designs out there. I'd say ask Lloyd Sponenburgh since he has a nice setup for that, but he refuses to wade through the off topic posts in this group anymore. If you like you can usually reach him on the CamBam forums. I think Lloyd and Bubba on that forum both run DIY micro droplet applicators. |

Ah. I was hoping to do this with much less pressure. My neighbors would get irritable if I were running the compressor that much.

What about an artist's air brush? I use one to coat parts with anti-firescale juice and run it at about 10psi.

If it doesn't work properly, they'll usually refund your money and -not- ask you to spend the normal $18 it costs to return something to China. If it's a real small-diameter coolant tube and real small venturi orifice, it may take a lot of pressure, but not airflow, to get it to work. For mist, it should be teensy. If it's large, you have an HPHV paint sprayer on your hands. (Oops, China.) I picked up some misters for my garden from Chiwanese vendors. They're very fine sprayers, not misters/foggers or the "atomizing nozzles" as touted. Not too bad, but not quite what I expected. 20 for $3.49, delivered, so I'm not too upset. -- However beautiful the strategy, you should occasionally look at the results. -- Sir Winston Churchill |

A simple carpet-insulated (interior) box/shack around it can cut much of the noise from reaching irritable ears. (That includes mine.) He Who Always Replies To Trolls was right, too, that adding capacity to your air tank might help. It'll take longer to fill but twice as long to come back on. Better yet, do both. P.S: If this is the one you bought, you overpaid. g http://tinyurl.com/yc7nwrtd "Grades: 1. Clean the fluid should be used. 2. Do not use corrosive liquid. 3.

Well I'm guessing that the DIY droplet sprayer will use a modest amount of air, and not cloud up my 400 ft^2 shop. So, I'm just gonna go with that. Thanks Bob!

Larry, you seem to have a different customer service experience than me with Chinese Ebay sellers. There are never any instructions, and when you write them they write back with some nonsense which is completely irrelevant to your question. Sometimes they give a refund. Sometimes they even try to bargain when you get something totally defective. "Is it OK to refund half? After all, we did pay the shipping..." Anyway, for ten bucks it's not worth getting into it with them. In this case I would say that the unit does work, but just not as I had hoped. I would have to run my compressor continuously to supply the needed air, and I would fill my shop with fog in a short time. |

Cause yes..they certainly WILL raise a hellish fog when you have several of them running at the same time, once you go past a certain point of liquid in the tool. http://koolmist.com/coolant-systems http://koolmist.com/formula-78-for-light-duty Improved Coolant for Mist Systems New formula improved after years of research, Formula "78" is a chemical base mist coolant that dissolves in water to a clear solution. It is the most universal mist coolant available. It can be used on any metal or alloy, and displays high efficiency in the cutting of exotic metals and alloys such as Monel, Inconel, Titanium, etc., as well as all non-ferrous metals. Formula "78" meets all OSHA standards. It is free of halogens and sulfides. It is safe for operators whether in liquid or mist form. Our proprietary formula completely prevents dermatitis and rancidity, and the formulation contains no irritants. All components for Formula "78" are dissipated into the atmosphere by cutter heat except on; a chemically compounded lubricant that clings to the tool to reduce friction, the prime cause of heat. Formula 78 - For Light Duty Service Part Number: 78-1 = 1 gallon (in plastic bottles) Part Number: 78-4 = Case (four 1 gallon plastic bottles per case) Part Number: 78-5 = 5 gallon pail Part number: 78-55 = 55 gallon drum Kool Mist Universal Flood or Mist Coolants The Kool Mist unique formula of coolant is safe for people, working materials and the tools used to shape them. The cost to use Kool Mist is about $.03 per operating hour. Because Kool Mist comes in concentrated form, it may be diluted with water in solutions up to 32:1. One gallon therefore makes 33 gallons of mix, or enough for 33 eight hour shifts at typical usage. Both Kool Mist coolant formulas are biodegradable, greatly reducing storage and disposal concerns. Spent coolant requires no special treatment and will have no adverse environmental effect. The improved Formula "77" is highly recommended for mistcooling any metal or alloy where tougher machining condtions require greater lubricity. It is particularly useful where tool pressure is exceptionally great or where the material is very abrasive. Formula "77" provides the extra lubrication needed to protect the cutting edge of the tool. Formula "77" has been reformulated to provide the same safety for use as Formula "78" where incorporating additional lubricity ingredients for more demanding machining applications. In addition, Formula "77" provides excellent service in most general purpose flood cooling applications. One coolant-Formula "77" - will fill most of your general mist and flood coolant needs. Formula "77" eliminates double coolant inventory, cuts storage space requirements and reduces your costs. Formula 77 - For Tougher Service 77-1 1 gallon (in plastic bottles) 77-4 Case (four 1 gallon Plastic bottles per case) 77-5 5 gallon pail 77-55 55 gallon drum Formula "77" - like Formula "78" - will not cause dermatitis, rancidity, or buildup: and creates no rust or corrosion when diluted with clean water. Workpieces and machine parts remain clean and unstained." There are a number of makers of misting compounds ..all with their own claims Gunner --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Also, I usually ask questions to half a dozen vendors at a time, then compare any replies. Write it up, Ctrl-C, Ctrl-V six times, and send 'er on. If the average price is $10, look for the vendor selling it for $27 and ask him. He'll find the answer for you. Sometimes they give a refund. Sometimes they even try to bargain when you get something totally defective. "Is it OK to refund half? After all, we did pay the shipping..." Yeah, I've had those, too. I ordered a nice black backpack and got a pink and green camo. First he offered $6 back, then $9, then $16, but I finally asked him to either send the black one or refund the entire amount. I'd already wasted 5 weeks. He caved. All that exchange added up to about ten minutes of my time. Anyway, for ten bucks it's not worth getting into it with them. In this case I would say that the unit does work, but just not as I had hoped. I would have to run my compressor continuously to supply the needed air, and I would fill my shop with fog in a short time. I consider a few minutes worth of email exchange a fair exchange for a $10 (r $36) refund. YMMV. Obviously, the thing was built for a much larger setup than you have. Hey, you have a machine shop and an example of a too-large mister. Care to make one yourself, on a smaller scale? I think all of these would fill the shop with fog pretty quickly, though, and I'd want an air source and outlet fan for when I was using it, I think. It's messy enough to make a fella want to hover over it with a hand mister, I tell ya. -- However beautiful the strategy, you should occasionally look at the results. -- Sir Winston Churchill |

Cheapie Mist Coolant Unit- think I can get it to work?

Mine's a 3HP. Yes, it's louder than a cooling fan but you can still carry on a conversation without raising your voice while in the same room, can still talk on the fone and/or watch tv. Outside you can't even hear it. -- for full context, visit http://www.polytechforum.com/metalwo...rk-641660-.htm |
