Although I have many spare pressure tubes,  my first one has seen more action and is crystal clear unlike yours which looks like it's been through three wars!

 [big grin] [big grin] [big grin]What's the purpose of this tube? I didn't use solvent to clean it because I'm afraid of breaking it. Once the gun is leaking, it is a mess everywhere and very hard to clean.

I am still getting air bubbles. If the weather is nice and material is thin enough, I was able to get smooth finish but still with bubbles no matter how far/near I put my gun to the surface or how thin or thick the coating is. What's the possible solution to get rid of it without respraying the whole board? Thanks a lot!

The gun is broken, you'll never get a good finish with defective equipment.

Call Fuji, tell them bout the problem. Hopefully they'll send you a replacement gun.

Agreed.
The gun is not operating correctly.
Call Fuji, they are really good to deal with. I believe @JCLP knows the name of the guy to speak to.

I contacted fuji and they asked me to mail to a place they have contracted with and no one is there @1pm to receive the package. So I expressed my concern that I need this thing fixed as soon as possible. CS suggested me to buy  a m-series gun.  [sad]  At this point I am idling.

BTW, I found it is so hard with bottom feed to spray anything close to the ground. Any suggestions?
Another issue is how to spray up inside of the cabinet as the board is not movable and visible when look up.

Thanks a lot and best

Add the PPS system to the gun, you can spray with the gun upside down.

In time you'll learn to spray blind.

You need a #18 adapter. Make sure the cups you order are HO style. I believe the "most confused"[big grin] one has a post with all the variations in this section of the forum.

Here is a link to what you will need for the T70 bottom feed gun.

PPS for T70

I believe you can order from these guys. Or just call them and they will guide you. Fuji Spray also recommends dealing with them.
Cheers,

You can't convert your bottom feed to top feed ( gravity). You will have to purchase another gun. The T75 gun. The needles and cap set for the T70 is compatible with the T75. If you go with the M series or GXPC gun you would need to purchase additional needles and caps as they are not the same as the T series.

Yes, it will still be a bottom feed, but you can flip the gun over, spraying with the cup and hose pointing up (the gun will now spray in any position, (this is true if you're connected to a separate pressure pot also). You cannot do this with a conventional cup on the gun.

The PPS system uses a flexible material liner so when start off, you bleed the air in the liner above the material.  That being, it allows spraying at any angle as there is no air pocket to deal with.  If you ask me, if the cup is above or below the gun, either way it'll be issue in some situation.

If you want the best "all angle" setup, you'll have to go with a pressure pot system.

Thank you all. So PPS can let you spray more difficult angles and provide easier cleaning. Does it provide better finish result? I am debating whether I should spend $200.

I found amazon has cheaper price and wonder whether I missed anything. Below is all I need for PPS system, right?

3M 16054 PPS Adapter 18 $28.05

3M 16124 PPS Type H/O Large Pressure Cup $66.75

3M 16024 PPS Large Kit with 200 Micron Filters $62.70

Thank you!

Finish quality is ultimately in the hands of the person holding the gun.

Did you contact Fuji about the T-70?

I got the gun back today. They changed a nozzle and screwed the new nozzle super super tight. No leaks anymore yeah! But should I do the same? I just don't want to damage the gun.
