Thread: Fog machine "tune up" and maintenance

Tweet

I'll probably putz around with a bit, maybe see if I can take the pump out and clean it. I think the pump might just be failing though.

I was just checking target.com, they sell a few 400watt units. They also sell a remote timer for $10. It is just like the one I have on mine. Does anyone know if their $19.99 or $39.99 unit can use this timer (the one they sell)? I ask because I spent $9 for a some 3 conductor power tool cord at Home Depot and replaced the cord on my timer with a 20 foot one. If I could buy another cheap machine and use my timer, that would be great.

The website doesn't say if the fog machines can use the time, or on the timer page, what machines it can be used with....

I bought the target machine and timer last year and they work fine for small areas. The machine housing is plastic and on the flimsy side, but they work.

cleaning PRIOR to storage is always good.

BUT.....

If your 1200 is clogged... chances are you can just goto Wallwart and get a replacment pump out of one of those $19.95 400w machines...swap the pump, and yer back to foggin'!

I took it apart last night, drained the tank, took off the high pressure line from the pump, put some water in the tank and jumper-ran the pump. Some water dribbled out, but I could easily stop it by putting my finger over the pump outlet. I would expect this to be a pretty high pressure pump. Anyone ever test one like this?

I have another non-timer fog machine that I may see if I can scavenge the pump out of. Looks like a similar manufacture and design (so far).

Anyone ever test a pump like this? The sporadic, bursty and low output of this machine could be explained by a bad pump....

I dont know why I never thought about pulling pumps from cheap 400w machines (after halloween sales) to replace my higher wattage pumps when they go out.. /facepalm


but just to say whatevery one else is saying, I have owned many many many foggers over the years and I never clean them, the only time I will clean them is if the fog output starts to diminish.

I kill mine when I have several running at once and one (or more) run out of juice on me.. ive tossed a few in my day

I cleaned the first fog machine I bought years back, using the instructions you read about, after I used it then it never worked again. I never cleaned any of the others I bought since and they kick of fog year after year.

I am responsible for maintaining a bunch of fogger units. We run them year round, roughly 14 hours a week. We use three models. Chauvet 1250, v-940, and Jem ZR33. I have seen lots of articles talking about cleaning with distilled water and vinegar. DON'T DO IT! Hopefully the attached picture uploaded OK. This is what the inside of your machine will look like if you do.

The pumps are not high pressure at all. The pressure is from the oil heating up. I have had a few pumps "sieze" on me after 6 months on the shelf. Taking the pump apart and cleaning it up seems to do the trick. I have never had to replace a pump.

If you still have a little bit of fog coming out, jumping the pump and running straight simple green through the unit works wonders. Make sure the unit is not hot when you do this though. Once you get a little simple green out of the nozzle, turn the pump off and let it sit for about 15 minutes. Do this a few times then run straight fluid through the machine. Now you should be ready for business.

If you have zero fog output, you may be done for. The chauvets and the v-940 can be taken apart. If you need some pics and instructions, send me a message. I am not sure about the box store units though. If you have a blocked ZR-33 you are out $389 bucks for a replacement heat exchanger.

Hmmm. I have never cleaned my fog machines and they have always worked. I would buy the small ones during the after-season sales. My maintenance technique was not planned just a combination of a lack of will to read the manual and laziness... I guess that's kinda the same though.

It's odd that in this situation, neglect is your friend. I never got around to cleaning or dumping the fog out of my machine last year... and apparently that was a good decision. Looked in the fogger tank today and saw some mold though...

Is'nt "fog juice" just glycerine? Glycerine is water-soluable and it's non-toxic (and is used in many foods). I have a fog machine that was exposed to water and it caused the pump/motor to clog up. I am not sure how to dilute it yet since water isn't working.
