Eliminate the Haze with the Fog Buster

Tormach has partnered with FogBuster to bring the best mist (actually, zero mist!) coolant system to the Tormach eStore.


If you’ve used other misting systems before, you surely understand how quickly they can fog up the entire shop without a serious ventilation system.  For a small garage or basement shop, they’re nearly impractical.

So…what’s so great about the FogBuster?  Well, a picture or two is worth a thousand words…

Typical Mist Coolant System Most Misting systems create a dense fog because the drops are too small.

Normal Misting system = Haze

Fogbuster non-Misting Coolant system FogBuster Coolant System controls the drop size and doesn't atomize the spray

FogBuster = No Haze

No Mist!  Instead of atomizing the coolant into a vapor, the FogBuster System produces a stream of larger drops that provides all the advantages of mist coolant without fogging up the shop.   You can use it with any coolant, and since the FogBuster puts all the coolant onto the workpiece and tool and not the air, you’ll use less coolant as well.

We’ve added a PCNC mill integration kit for the FogBuster that includes an air solenoid valve so you can control with either M8/M9 commands (in lieu of flood coolant) or the flip of a switch – whichever suits your shop best.

Here’s a video from FogBuster showing the system in action.

    I have been using FogBuster products since 2001. When I had the shop, I had a dual nozzle Fog Buster on both my FADAL and my Haas.

    What’s really great about the Fog Buster is you run a airline to the unit with 100 to 125 PSI to pressureize the tankand then regulate it down to 6 to 15 PSI at the nozzles.

    I use the Fog Buster on my PCNC, band saw and drill press.

    My opinion, you won’t go wrong by adding a Fog Buster to your PCNC. It will even work on the Duality Lathe where Tormach says you shouldn’t coolant.

    Gotta love it.. Just purchased a Kool Mist system, modified it, purchased a 12v SMC valve, Parker Regulator and all the Parker poly hose and push lock fittings. Glad I didn’t install it all yet. Ebay anyone??

    This looks much better. Thanks guys for all your continued R&D.

    We’ve tried them both. Consensus here is that the FogBuster is superior. We can run it all day in our shop without even noticing its on.

    How much air (cfm) does it need when it is in operation?

    What is the best coolant to use – can a 10:1 dilution of typical coolant (say Hangsterfer S500) be used?

    It’s really great to see Tormach continuing to release products like this.

    Unit uses very little air.I never run mine over 15 # and usually much less. Have been using for over ten years and have them on my lathes and Tormach. Made one unit on portable stand that I can move to any machine when needed.
    Remember the cooling created by evaporation with the air flow and coolant really works. No need for large amounts of coolant. I’ve been using a premixed coolant from Enco. part # TP296-2347 I like it.

    Yes, exactly. It needs less that 20 psi. We use Premier 600, but any coolant will work

  • June 25, 2012 at 2:02 pm

    Thanks Andy & TnT, but how many cfm are required? At present I only have the small compressor that Tormach sells for the PDB and I suspect that 3-4 cfm won’t be enough for both the PDB and the FogBuster.

    Also, can you confirm that the coolant would get diluted with water, if that’s what the manufacturer reccomends?

    Finally how long does the 1/2 coolant reservoir last – hours or days?

    Thanks, Mike

    Mike, I don’t have exact answers for you, but anecdotally, we have run 2 ATCs AND 2 Fogbusters at the same time on one of our Syclone compressors that we sell during our CNC workshop class at our shop and it wasn’t an issue.

    Yes, definitely dilute or mix the coolant as the manufacturer recommends; we use the same mix for both flood and fogbuster.

    As far as how long it lasts, that depends on how the flow is adjusted, – to throw a number out, maybe 1/2 gallon would last 1 day, on average.

    Hi Mike,
    I’m running a lathe job now and using more coolant flow than usual because of heavy cuts on 303 s.s. In over 4 hours use I have used less than half the coolant. Not a real concern, especially when you learn how to adjust the
    unit for the work at hand. Remember more is not better.

    Would/does a mist sprayer replace flood cooling altogether or would you chose one OR the other depending on the material being machined and the operation? Can you suggest further reading on near dry machining?

  • June 26, 2012 at 1:23 pm

    Thanks for the added info. Coolant capacity seems more than enough for me and it sounds like the Syclone would suffice for the short to mid-term.

    I don’t think mist coolant works well if chip evacuation is an issue – for example, a deep pocket. Flood coolant is a much better choice in that situation. Regarding near dry machining, my understanding is that the cutting tool materials are key – check this out.

    I have used the FogBuster since 2001. I have had a 1/2 gallon tank of coolant anywhere from 2 days to 2 weeks depending on what I was cutting.
