Fog Machine overhaul

Well my poor old fog machine, after so many hours of use was pumping no where near the amount of fog it used to. So I took my toolkit to it. The idea is simple, a small pump from a tank, feeds the fog juice through a very small diameter tube through a heating element.

All pipes seem to be clear, so I tracked down the fault to the pump. Although working it was just not pumping enough fluid to produce a lot of smoke, so feeling a bit brave, I disassembled the pump. It consists of an AC coil with a springloaded plunger and several o- ring sealed chambers, stacked above each other. Fog fluid or Propeleyne glycol, is a syrupy sugar type of chemical and crystals and a sludge had formed in the tiny cavities that fill each chamber. I took the whole pump apart and soaked and cleaned each component in isopro alcohol and reassembled.

WOW, this thing is now kicking out more fog than when it was new, I recommend this to anyone whose fogger is a bit tired or seems to have given up. DO NOT use a vinegar solution as I have read on some web sites , as this will corrode the very delicate O ring seals. I thought I would share this with you.

Very very interesting to hear! You should have taken some pictures while you were at it! Oh well, maybe when someone else is as brave they will take a fex pictures.

hey that is EXACTLY what happened to my fog machine! it used to sputter, and sometimes the fog didn't come out untill like 5 seconds of pressing the remote! although the pump wasn't clogged up, it just stopped working, so i had to order another pump, and now it works perfectly! the pump was only $23, so i was really happy that i didn't have to buy a new fogger!
