I researched many HVLP and LVLP sprayers before buying this because I have a small air compressor with only 1.5 Gallon storage capacity and 3CFM at 40psi. Many discussion groups simply tell you that with such a small compressor and low CFM, you can not hope to get good atomization and spray results with any type of gun. But having used this LVLP 1.3mm gun (I have yet to use the 1.7mm nozzle), I was really amazed at the quality of the spray at just 20 PSI setting at the gun inlet with trigger fully pulled and spray pattern set to circular (but 65 PSI setting at compressor). It needs about 25 PSI if you adjust the spray pattern to fan-shaped because some air has to be diverted to shape the spray beam through the nozzle horns. The design of the gun gives you very fine control of the air volume, paint density and spray patterns. If you compare this design with some of the most expensive IWATA guns (e.g. http://store.summitracing.com/partdetail.asp?part=ast-39570) , they are similar- especially the location of the air-volume control knob. Somehow, I feel that an in-line adjustment creates less turbulence in the internal air stream than the transverse type of adjustment (e.g. http://www.spraygunworld.com/products/Titan/19200.htm). By playing around with the 4 parameters of a: Pressure at Compressor, b: Pressure at Gun inlet, c: Paint density, d: Air volume- you can get good atomization and spray results. BUT something has to give- at the fine atomization needed, the amount of materials sprayed is less than that from a higher CFM gun. I guess this is plain physics of balancing the amount of air and paint whilst maintaining atomized droplet size- less air means less paint. For the occasional projects around the house, I feel this reduction in speed of coverage is amply compensated by the nice professional results that you can get out of these LVLP guns. Compared to brushes, the results are much better and the paint covers 3 times more area approx. The guns are well made with chrome all round.

A6034 is priced low but still provides good quality spray like more expensive units. Sprayer nozziles are 1.3 mm and 1.7 mm, which can produce good quality paint.
It sprays polyurathane, stains, and all types of oil-based finish materials without having any trouble. The output quality is fairly good.

I used 1.3mm nozzle to spray urethane for bookcase finish. I could spray the stain easily and achive the very consistent output. Also I sprayed the final finish and its surface is silky smooth. That is the point I'm happy for the purchase of this gun set.

The entire finish process for bookcase was much faster than brush painting, took less than 1/10 of time. Also it uses very small amout of paint. Due to lvlp, it saves a lot of materials.
Clean up was easy too. Just pour mineral spirit a little in the cup, rinse it, and spray through the gun. It cleans up real easy. I've used this gun more than 10 times now, so far have no problem using this way.

But I've had ample problem on spraying latex paint. I dilued latex paint with water and tried floetrol also. Neither way was working well, it just spatters because latex paint needs bigger nozzle, at least 2.0mm.

I tried to contact this company and found the web site, but all facilities are in China and Taiwan. Sent emails twice to inquire about purchasing bigger nozzles, but haven't received any response from the company or their CS over a month.

So I decided to buy PC PSH1 with 2.2mm nozzle kit to spray latex paint.
Overall Ampro quality is good enough as long as you spray oil-based finishes. Also the gun set is not for automotive type fine finish. If you need that fine finish, you have get a gun, which has nozzle size less than 1.0mm.

I've been holding off purchase of an HVLP spray set up for two reasons. Fisrt, the gravity systems have required 8 to 12 CFM airflow to operate properly and two, the turbine systems are yet another item to store in an already overcrowded garage / workshop.

These guns operate nicely on 3 to 4 cfm at 30psi and they works great with my 3 gal shop compressor, even on larger furniture. I've been spraying two coats of General Finishes Milk Paint followed by wipe on Glaze with two or three coats of Water Based Poly (General Finishes). The 1.7mm tip provides a well atomized, easy to control coat with these products. I had one older can of paint that required a little thinning but otherwise I've sprayed right out of the can. These are very nice finishes and readily available.

Cleaning is easy, especially if you go buy the disposable gravity cups from Harbor Freight ($6.99 for several). I just dump out excess paint, flush out with a spray of water and take it to the sink. I've been removing the front fan piece and spray head so that I can run a brush through it but I'm not sure you have to. It only takes a minute or two so I do it.

Overall very pleased with these for much less money than I expected to pay. My only reason for the four star review is that the adjustment knobs could be smoother and of higher quality, minor issue overall.

La razón principal por la que adquirí este producto es porque dispongo de un compresor de 24lt (7 CFM), y esto me impide usar con comodidad pistolas HVLP. EN función de ello, estas pistolas son perfectas, ya que tienen un consumo promedio de 3 CFM, lo que me permite hacre trabajos a buen ritmo.

Hasta el momento, no he utilizado las pistolas, ya que espero otras herramientas para iniciar el proyecto. Sin embargo, debo decir que la construcción de las mismas es bastante sólida, y como dato adicional, el kit incluye además el set de limpieza, un filtro para copa y un anillo con conexión tipo espiga. Las copas son de gran capacidad y ademas, el acople entra la pistola y el tanque utiliza un filtro para evitar que solidos ingresen al sistema de inyección.

Si se coloca el manometro que incluye, y se utiliza toda la capacidad de la copa, es posible que se torne muy pesada la pistola, por eso puede ser recomendable no usar su capacidad al máximo (1000 cc), y obviamente puede no ser necesario ya que hablamos de una pistola de bajo volumen y baja presión.

En conclusión, recomiendo ampliamente este producto, buen precio y caracteristicas adecuadas para DIYs (Do it your selfer)o pintores a domicilio.

Más adelante añadire comentarios sobre el acabado y rendimiento.

these guns worked perfect ,used them to spray toner on cabinets,worked good with just a pancake compressor.very happy with this purchase
