Before I recommend the sprayer, I need to explain why we now recommend the sprayer machine instead of the roller brush or brush.

At present, the paint machine on the market greatly improves the efficiency of the contractor, because the spraying speed of the sprayer machine is 5 times that of the rolling brush and 12 times that of the manual brush, so we recommend the use of the sprayer machine when spraying in order to improve the efficiency of the project and reduce the labor cost.

Then when you can't choose the sprayer machine you want in the many airless spray machine brands, maybe below tips can help you.

1. Firstly，you need to determine how much paint your project will need per week.

Here I will use our AEROPRO airless machines 515 or RONGPENG R520 as an example, which like the Ultra Max PRO series on the market, can meet 50-100 gallons of spray per week in medium residential, repaint/remodel, property maintenance, light commercial.

2. Secondly, you need to make sure your main spraying paint types, like AEROPRO 515, Ultra Max PRO series they can not only spray for example DULUX, PPG, NIPPON, SKSHU, Carpoly the Lacquers and Stains, Interior/ Exterior Latex, Enamels, Acrylics of these brands, It can also be sprayed with BASF,SIKKENS,PPG,NIPPON and other brands of Oil-Based Primers, which is more suitable for multi-scene applications for contractors.

3. Consider machine performance. Under the same spraying application and the same working pressure of 3300PSI, the machine flow rate of AEROPRO airless paint sprayer 515,RONGPENG R515 are 3.5L/M, and the flow rate of Ultra Max PRO series around 2.3L/MIN. The Ultra Max PRO series are priced around USD$2000 per unit on Amazon in the United States, while the AEROPRO 515 is priced around USD$450 per unit on Alibaba . The AEROPRO professional paint sprayer 515 more cost-effective.
