Sata HVLP vs RP

i’ve lately been considering picking up a new gun. I’ve always used sata. started with nr2000, then 3000, now 4000b. i’ve looked all over trying to find the real difference between my current 4000 and the new rp.
i’ve been to satas website and still unclear on the real difference. some people prefer it for clear but then some base. it wouldnt be that hard at all to call my jobber and get one for demo but before i do, i want your expert opinions, WHATS THE DIFFERENCE?Are you talking about the 4000rp vs the 4000hvlp? Or just rp’s vs hvlp in general?In short the difference is atomization and speed,the rp’s will use more material, atomize better,lay down a smoother coat of clear vs hvlp.
The difference in general but if I decide to get one it will be the 4000.
Are there any major differences in the new 4000 rp over previous ones?The 4000 RP is the most loved one around here. Its a little on the slow side but will lay the smoothest finish.

Slower than the previous versions of the RP.[quote=”ding” post=28891][quote=”cbhvr6″ post=28890][quote=”smooth” post=28885]The 4000 RP is the most loved one around here. Its a little on the slow side but will lay the smoothest finish.[/quote]

my jobber has a 3000 rp that i’m going to demo. wanted a 4000 but he didn’t have one available. if i like it i’ll just buy that one.
thank you all for the info
:hij: I just ordered a satajet 3000rp brand new from the UK like the ones Andy was talking which they apparently have released in anodised blue.
not that i bother much with Sata guns anymore but from what i gather the 4000 RP hasnt been recieved that well and most folk i talk to prefer the older 3000 RP model ,even my rep admited as much after being pushed but he has to sell what he has to sell 😉
as for RP guns useing more paint than HVLP it actualy depends on the paint as the reverse can be true ,higher viscosity material ie clearcoat requires more velocity to get it to the panel ,RP guns provide the added momentum to enable this , with a HVLP heavier less atomised materials can drop out of flight and not actualy transfer to the panel ,with lighter materials HVLP wins as there is less bounce back and it will also achive better atomisation than it would with higher viscosity material so it is simply not all about the finish quality when it comes to RP guns ,for clear and HS materials they actulaly save more paint than HVLP when it comes to spraying the material they where designed to spray
heres an example of just how efective higher pressure is when it comes to transfer rates and finish quality ,the latest Devilbiss JGA Pro conventional HIGH PRESSURE guns which are concidered thier finest refinishing guns [sadly not legal in a bodyshop] actualy have transfer rates of 63% ,to be compliant requires only 65%
claimed transfer rates can be very deceptive and that is how HVLP is often mis sold or mis understood ,conventional spray equipment in the hands of an experianced sprayer is not actualy the vilian it has been made out to be and from a painters point of view i would rather sacrifice a little more paint to the booth than have to sand off even more material to correct orange peel
RP overall is a good compromise if you have to choose only one gun ,for basecoats then yes definatly HVLP all the way
BTW if you want guns that will imho outperform Sata at half the price look no further than Walcom guns my old FX HA was one of the finest clearcoating guns i have ever used ,i sold my sata RP within a week of buying the Walcom ;-),currently i am useing an Optima 900i by Bersch and Fratscher ,simply sureal and agian imho superior to any Sata model i have ver used

that is pretty much the explanation i was looking for. being the only painter at my shop, there is no one to discuss things like this with. nor can i compare different guns. i can not justify buying a gun without trying one first. so i will take your recommendation and also try to demo a walcom and see which i prefer.
my old Walcom was a 1.2 FX HA, this has been superceded by the latter more easily serviced Genesi HTI or HTE or whatever they call thier compliant/RP versions lol
so basicly if its an all rounder and clearing gun then whatever you decide brand wise i would recomend the RP AKA compliant versions over the HVLP ,also i much prefer RP for waterbournes
Oh and check out both the Iwata WBX gold aircap as used by Aston Martin for clear and the new Ballaria which has a flatter more even pattern ,much more economicaly priced than Sata and imho better built ,i will be getting myself a Supernova soon WS version off a friend ,i have seen the results he gets from it and have used it for a small job myself so hopefully it will be a good gun for me ,they do however require a bit of user input to tune them in for faster aplication techniques,myself i like to work at a slower pace anyway ,finish being more important than speed for me which is why my Sata RP and my Walcom where both 1.2 set ups ,one it slowed them down to my pace and two i felt the finish was superior to the larger tip sizes

Actually I like the 2000 RP the best :stonedI don’t know if its only me that does it but, I’ve got for different clear guns with different set ups. Due to doing all different vechiles for insurance work, know I can’t say which better or worse as I don’t know what finish your trying to get. Is it for your every day car or custom builds etc. I have to match my clear fresh paint work with the clear finish that’s on the car. Over the years you seem to pick up which guns are best for the finish you need. Know I now painters that use the same gun every day but are always playing round to get the pressure rite etc to try and match the car. I ways think if you can match the car so you can’t see the difference in the clear coat between the old and new it’s turned out gd ha ha
I haven’t upgraded to the 4000 series because I dont see a need for it right now. I use a 3000hvlp for all my metallic basecoats. I use the RP for solid colors like white, black, red, and clear. I do it that way partly not to have to use solid colors in a gun that once had metallic in it, and IMO the RP lays out clear nicer than the HVLP. Although, if I was going to buy one gun to do everything, I originally used an RP for everything, but it is nice to have both.
Bottom line – Both guns will get the job done, it’s really preference. Both guns are capable of producing beautiful outcomes.
