High pressure airless paint sprayers use a high-pressure plunger pump to pressurize the paint to 3000 PSI (210 kg/cm). The paint is delivered to the spray gun through a high-pressure hose, and the pressure is released through the nozzle to form atomization that creates a dense coating on the surface of the wall. Since no compressed air is required to atomize the paint, it is called airless spraying. 1. Before using this high-pressure airless spray machine, please make sure to read carefully and strictly comply with the requirements of this instruction manual. 2. The high-pressure airless sprayer must be placed smoothly and securely during the operation.

The development of the construction industry has led to the development of modern machinery, so the use of airless paint sprayers is still very widespread, so we need to how to choose airless sprayers supplier? First of all, we all know that many modern people will think that the big brands of paint sprayers will be better, this view sometimes we can not deny, like many big brands in the world now, like Germany's Wagner, like the United States of America's Titan, these are among the world's top airless paint sprayers companies, so from the function, from the use of innovation is better, this is true, but we have to look at its price, the price of such brands is very expensive, can achieve the effect we want, but can not reach the case of our earnings, can not be affordable to buy, how to choose airless sprayer manufacturer is more critical. The first thing we all know is that we have to look at the price of airless sprayers, so we exclude many of the world's top brands, from a practical point of view, to buy cost-effective Chinese sprayers is a good choice. For example, China Fuzhou Yazhong Machinery Co Ltd, we are the source manufacturer and have our own factory, so our prices are very competitive. The second is the guarantee of quality. We have been in the field of spraying equipment for more than ten years and always insist on continuous research and innovation. Years of research and design are not as good as those of the world's top industries, but all our products have CE certification and quality is guaranteed. Then the after-sales service and guarantee is very important. The paint spraying machine is like our human body, through the continuous use of the old bad such a phenomenon, or the use of non-standard will lead to damage to the internal functions of the machinery, these are inseparable from the parts repair and after-sales protection. Fuzhou Yazhong Machinery Co Ltd not only produces airless spraying machines, but also produces a variety of spraying machine accessories, so in the after-sales maintenance has a wealth of experience and service capabilities. Finally, how to buy spraying machines or to combine their own needs. Either way, Fuzhou Yazhong Machinery is looking forward to any inquiries you may have, choose Yazhong Airless Paint Sprayers, your reliable supplier!

Airless spray machines are mainly used for spraying materials such as anti-corrosion and fire protection materials, epoxy resins, or emulsion paints. When choosing airless spray tips, we need to understand the spray width and flow rate, the nozzle flow rate is the size of the calibre.　 There are generally three types of nozzles, standard, finishing and abrasion resistant, indicated by the English symbols LTX (standard), FFT (finishing) and GHD (abrasion resistant), with the coded numbers introducing the spray width and aperture data. According to their needs, consumers can choose the model you want to buy, the following are the things we need to pay attention to when buying airless sprayer nozzles. Firstly, when the airless paint sprayers is used for spraying emulsion paint, in order to ensure the efficiency of the construction and the thickness of the emulsion paint, it is best to use a standard type of nozzle with a five-inch radius and a 0.0017-inch diameter as the best option. When spraying the corners of the walls, it is necessary to switch to a nozzle with a relatively small spray width. When painting external walls, we can use a nozzle with a spray radius of twelve inches, which will increase efficiency. However, as the spraying range becomes larger, it is best to choose a larger spraying machine to ensure uniform thickness in order to ensure the quality of the spraying. Secondly, when paint spraying machine spraying oil-based paint, we need to pay attention to the characteristics of the paint, oil-based paint density is low, strong liquidity, when the spray width is large, easy to cause the paint hanging, this time we had better use the finishing type of nozzle, this type of nozzle atomisation effect is better, can be more liquid paint spraying more evenly, in reducing the wear and tear on the nozzle at the same time to extend the use of the nozzle time. Thirdly, when using the high pressure paint sprayer to spray fireproof and anti-corrosive materials, we need to use the standard type of nozzle, as these spraying materials contain granular substances on the nozzle wear and tear is more serious, so here we still recommend that you use the wear-resistant nozzle. When spraying anti-corrosion materials, we need to consider the problem that the thickness of the anti-corrosion material sprayed is relatively heavy, it is best to use a larger diameter nozzle when choosing a nozzle, but for steel structure of anti-corrosion materials, it is best to use a spray nozzle with a spray radius of 5 inches or less, so as to reduce the waste of paint and improve the use of paint.

Why do professional contractors prefer to use airless sprayers? Because high-pressure airless sprayers offer an easy and economical way to apply coatings. The most popular reasons are the following. First, airless spray painting is faster, allowing more work to be done in less time and using less labor. Airless spraying is 10 times faster than brushing or rolling. Second, high-quality airless sprayers produce uniform paint coatings on all types of surfaces, resulting in consistent, high-quality finishes. Third, versatile electric airless paint sprayer can be used on a variety of coating materials, including interior and exterior jobs, and can be easily transported from job site to other job sites. Airless sprayers allow you to get the job done faster, stay on site all the time, save on installation labor, and get more done with less labor and the same fewer headaches. Not only that, but spray paint machine also provides a consistent coating structure for better coating performance and a smoother, quality finish.
