Our questions

  • Why taking a HVLP system into account?

    At least for three reasons:

    • Higher transfer efficiency. You will use a smaller varnish quantity compared to a traditional system.
    • Limited overspray. Pressure is so low that the paint is gently applied without bouncing off on the surface, thus avoiding any product suspension in the air.
    • No humidity in the device. The heat developed by air compression in the fans can eliminate humidity. No device is required to eliminate humidity or reduce its quantity. This results in a better finishing and a corresponding cost reduction.

  • I have never spray painted so far. How long does it take to learn how to use HVLP system?

    Beginners do not need to get out of any bad habit, just as it occurs for expert painters. If you are accustomed to using high pressure guns, it will take some time for you to get accustomed to the HVLP system because the technique is a bit different. It is recommended to exercise with the material you intend to use for about an hour so that you get familiar with the various techniques described in the manual.

  • Advantage and disadvantages of the heat produced by HVLP turbines?

    The reason why turbines deliver hot air can be found out in their structure. Fans rotate at 18/22,000 rpm. in a motor. This will increase the speed rate of the air molecules coming into contact one with the other, thus giving origin to heat as a result of friction and compression. Dry air is also produced as a result of humidity evaporation.
    This phenomenon helps avoiding any halo that could be seen only once the product has dried. No dehumidifier is required to dry air just as in the case of traditional compressors. The disadvantage of this heat could be represented by the tendency to let evaporate also the products, such as the diluents, which are mixed to the paint in order to facilitate the coming out of the varnish to the surface. If there is not enough diluent in the material to be sprayed, the drying process will cause the so called "orange skin" effect. This situation is solved by adding more diluent in order to balance the loss caused by the heat produced by the turbine.

  • Why should I use a turbine if I can purchase a HVLP conversion spray gun?

    You would still have humidity and oil leakages out of the compressor and you would not have the efficiency, practicality and flexibility a turbine could offer to you. A conversion spray gun enables you to paint at low pressures, but it is driven by a compressor that would cause many problems you would not have if you used a turbine.

  • What does "STAGE" of a turbine mean?

    The stage of a turbine can be compared to a fan moving an air flow. When speed increases, the air flow is also increasing. Let us assume that the fan speed is at the maximum. How can we further increase the flow? By adding a second fan near the first one so that it can work in sequence with it, thus doubling the flow. The more stages you add, the more air flow is developed.

  • What are the advantages of a three-stage turbine compared to a two-stage one?

    A 3-stage turbine can deliver a higher pressure. As a matter of fact, the increase in bar/psi will break the particles of the covering product into smaller drops, thus achieving a better and more precise finish. The advantage also results in the possibility of spraying thicker products with a correct dilution and without any waste. Moreover, you can move more rapidly on a surface compared to a turbine with a lower pressure since paint can flow better. A 2-stage turbine requires more know-how and experience in order to achieve the same results of a 3-stage turbine.




  • When should the filters of a turbine be replaced?

    You shall always check the filters of a turbine before starting any work in order to achieve maximum efficiency. If they are dirty, they shall be replaced.
    Attention, not replacing filters causes the engine get burnt not being able to “breath”. This problem is being found regarding all types of the existing turbines for painting.
