Hi All,

I’m looking to upgrade my HVLP setup to a Fuji (haven’t decided on MiniMite 3/4 or Q3/4 Gold)

My question is in regards to the Gravity Feed (cup on top) or Bottom Feed options available with each gun. Can someone explain the pros and cons of each option so that I can make the correct decision the first time? Thanks!

Gravity gravity GRAVITY!

I have the mini mite 4 (more on that in a sec) and got the bottom feed because I didn’t like the design of the gravity gun (not the new one). Cleaning takes a lot more effort than the newer gravity gun, and requires the turbine to be on. Cleaning the gravity gun doesn’t require the hose to be connected nor the turbine to be running. Also gravity lets you get into tighter spaces. Also, make sure you’re getting the set with the newer gun. It has a much better design over the previous gun.

When I bought my MM4 the new guns weren’t out yet (GRR!!); had they been I would have jumped all over that gravity setup. Even now, when funds allow I’ll be buying the new gravity gun and selling my bottom feed guns.

Now about the MM4; I went for the 4 stage because it wasn’t much more in the long run, and it allows greater flexibility as to what can be sprayed through it. I chose the plain MM4 over the super/Q series because although the Q and super models are quieter, they vent the air to the cabinet, which can cause overheating. The MM4 is louder, but not obnoxiously so. About as loud as my shop vac. Again, not an issue since when you spray you won’t be right on top of the thing.

I put mine on a small platform with cheap casters off of an old tv stand:

Thanks for the great info…very helpful for sure. I hadn’t yet heard about potential overheating on the Q series. I definitely would not like to annoy my neighbors with noise but I regularly use a rigid shop vac. If it is not much louder than that, the MM4 might be the way to go. I currently have a setup with a 25 gallon compressor/cheap gun and am getting poor results. The compressor is the oil-free variety and is very loud. So it could actually be an improvement in the noise even if I get the MM4.

It definitely could be an improvement over the compressor; most certainly in the portability department.
I love how I don’t need oil/water filters, a regulator, etc. The turbine is a one trick pony, but it excells at what it does. I wish I had gone that route first instead of getting by on a small twin stack compressor and detail gun.

When I was researching which fuji to get I read a few reviews about the Q/supers overheating. Fuji’s customer service is amazing though.

If your vac doesn’t bother them the mm4 won’t. You spray for what, 20 seconds to a minute at a time? It’s not like it’s running constantly. My planer runs longer and louder than the mm4.

Now about the compressor/gun setup; you’re still having issues after following the advice in your other thread?

Have your say...
