Title: I have a Fuji Spray Q4 and the T70 gun and CA Tech Bandit 2 qt pot. Please Help
Post by: Mike27520 on November 22, 2017, 08:42 PM
Hello, I have a Fuji Spray Q4 4 stage turbine and the few T70 guns and CA Technologies Bandit 2 qt pot. How do I use these together. Have sprayed with the pot and ca tech guns w/ a compressor but never used with a turbine set up. Any advise would be much appreciated. Thanks in advance. Mike

I don't have a CAT pot so I looked at their website pictures.

It appears as if the pot is compressor pressurized.

Compressor to pot inlet, fluid hose to gun fluid port.

Turbine hose to gun turbine port.

Pictured is my set up using a Qualcraft pot.

ok, that makes since. I read that with a 4 or 5 stage you don't need a compressor to pressurize a pot. but your picture seems to be the way to go. Do you like that setup that you are using?

also, that little compressor is enough to pressurize the pot?

Depends on the fitting on the pot. You can pressurize the pot with a turbine.

Yes, it served me well for many years.

To answer your other question, Yes. All the compressor is doing is push fluid to the gun, turbine is supplying atomizing air.

so if you were gonna use a turbine with a pot you would just change the air in fitting to accept the hose from the turbine and use the pot like you normally would but the atomizing hose that comes out of the pot would also have to be able to hook up to the Fuji gun? wonder if it is possible to get those fittings and modify those things?

Here's a link to a picture of the Fuji pot.

I'd make an adapter to go from turbine hose to pot, then a garden hose splitter to get to the gun.

Thanks for posting the Fuji pot. I use a Devilbiss 2qt pot and one of my small air compressors to pressurize it to around 15psi.  It’s fine for stationary use but I also use my Q4 to spray all the woodwork in the new houses I build. This would save me a ton of time untangling the air hoses.

Not to change the subject, but if I were to purchase this compressor, Cali Air Tool- 15 gallon, how would this work on a pressure pot set up? Able to keep up? Or what about with just hooking it to a standard HVLP gravity gun

Have to know which gun.

A bicycle tire pump will work on a pressure pot. All you need is enough air pressure to get the fluid from the pot to the gun. Atomizing air comes from a source other than the pot.

I can run my Graco Triton off a 2HP 2 gallon CAT compressor. Just have to listen to what it's telling me.

I have this set up, well not exactly I use an XPS gun because it was easier to convert to accept the fluid line from the pressure pot.
I use a small Senco 1010 to pressurize the pot. You don't need more. Connect the fluid line from the pressure pot to the gun, the airline from your compressor to your pressure pot and set your pressure with the valve. Connect the Fuji turbine airline to the fitting on the gun and spray away.
Let me know if you need photo's.

This way more compressor than you need for the set up you referenced in your original post. It will work on a conventional compressed air system.
110 volt 2 HP compressors really can't keep up with the CFM requirements (>10 CFM @ 40psi) of a conventional compressed air HVLP gun. There are some LVLP guns that will work, but they are generally unsatisfactory for finishing large panels.
Hope that helps.

Here’s the setup I was planning on using. I have the gun already that I got from Ebay, the pot I need to get yet.
If this setup doesn’t work with the 15 gallon CAT compressor, the gun and the pot I’ll change whatever I need to. You guys know alot more about this stuff than I do.

According to California Air Tools the compressor will deliver 6.4 CFM @ 40 PSI. According to Coatings Atomization the gun requires 14 CFM. WE can ignore the pot, once it's charged it does not consume enough air to worry about.

The TomCat from C.A.T. is a conventional spray gun. My guess is you'll be spraying with atomizing air at 35-45 PSI. Call C.A.T. and find out if you should get an HVLP or a Compliant gun to go with the compressor.

Coatings Atomization Technologies is in Louisville CO.

Always fun when we have CAT and C.A.T. in the same post [eek]

I did some additional looking at C.A.T. website. Look at the FE-Line of guns. I would still call them and have a talk with them.

The FE is designed for spraying stain and toning where a light mist is better than a heavy stream. I have an FE gun. I wouldn't use it for production spraying. Not sure that gun will help unless @JBag09 is using this system primarily for that purpose.
He either needs to get a compressor capable of higher CFM's (>13 CFM), buy a AAA,  or use the turbine driven with the small compressor pressure pot set up  both of us favor.
It would help if we knew what kinds of coatings @JBag09 was spraying, how often and where (in shop, on location or both) then we could advise the best system.

C.A. Technologies makes a FE-LCFM gun

CFM is going to depend on the material sprayed - this is from their pdf
[attachimg=1]

You can also bundle the gun, compressor and pot together

Ok, the FE-LCFM gun ships with two different air caps so you can spray higher viscosity coatings. It a good gun, but the best 1.5Hp compressors still struggle to keep up with the demand when you need anything over 5-6 CFM. This makes spraying large panels or many larger pieces extremely time consuming and compromises the overall finish as water bourne coatings in particular flashing off very quickly and you loose your wet on wet edge.
The OP wants to spray KemAqua which has a viscosity rating of 28-32 seconds #2 Zahn Cup which means you are going to require a minimum of 6 cfm with the LCFM cap but realistically probably closer to 7-8 which means the compressor is running all the time and never really putting out enough CFM to cover your requirements. the LCFM cap essentially makes the gun a LVLP sprayer which reduces the amount of coating it is spraying.

The ideal portable budget spray set up for the average person is;

Turbine (pick you poison)

Pressure pot

Small compressor.

C.A. Technologies makes some pretty decent spray equipment (IMO) and a couple of years ago, Wagner purchased the company.  Their 2hp compressor is supposed to put out 7 CFM at 40 psi.  I guess it would depend on what kind of things your spraying 'on site' but if you look at the kit that I posted, priced out at $1,365 - that is very competitive with a Fuji Q5 and Fuji doesn't even include the pressure pot

California Air Tools - sounds like their trying to ride on CA Technologies coat tails....

I am pretty sure it is Tom. I compared the two and they are very close with a little cosmetic differences...except for the higher CFM rating of the Coating Atomization Technologies compressor. Not sure how they are getting that extra 1 or so CFM that the California Air Tools don't.

They look very similar but the specs are different
http://www.californiaairtools.com/industrial-series-of-ultra-quiet-air-compressors/cat-4610alfc/

You may be right or this maybe a case of a 'knock off' being produces by the same factory in China and resold under different names in the US

[attachimg=1]

real quick comparison - didn't put a lot of time into this;  Look at the red squares.  CA Technologies on the left - I would imagine these are the actual pumps that sit a top the motor.  Note the size on the California Air Tool compressor on the left and the extra 'plumbing' on top circled in red.  The C.A.T. is mounted to what looks like a full metal plate on the bottom, the California Air Tools looks like it is mounted to metal 'straps' and the bolts that hold the motor case together are cleary visible and they are not the C.A.T. Compressor

I am sure it will do 7 CFM at peak, but press the trigger on the gun and you are not gonna have that much air on a continuous basis, but the practical realities of a single phase 110-15 volt 30 amp circuit may have a bigger impact. I have a Bosch 2 Hp compressor. It must run on a 30 amp 110-15 circuit or it will blow the fuse.
It's cheaper to just get an airless and spray Advance.

They (California air tools) used to have one with almost identical  CFM specs. There was a .4-.6 difference maybe.

California Air Tools

I sent an email to C.A.T to ask about the similarities between the compressors...

UPDATE - You guys were right, here is their reply:

"we actually get our compressors from the same supplier who manufactures the compressors for California Air Tools. So essentially they are identical, except we have about a dozen at a time private labeled for us"

Sorry for reviving an old thread but I'd like to ask Tom what kind of whip hose are you using? I am wanting to add a 2.5 gallon pressure pot to my setup and am concerned about the original fuji 25' blue hose being too stiff during spraying. The yellow whip hose you have in this photo looks like something that would provide a bit of flexibility. Thanks!

I don't have a CAT pot so I looked at their website pictures.

It appears as if the pot is compressor pressurized.
