For professional paint sprayers, airless sprayers are a necessity, and they get the job done at least three to four times faster than traditional brushes. There are many factors to consider when choosing the right airless sprayer for your job, and we introduce some necessary parameters here. Among the many professional sprayers, RONGPENG airless paint sprayer R750 is the recommended choice.

Professional paint spraying contractors are responsible for the anti-corrosion of large building steel structures, internal and external surfaces of ships and factories, and large-area spraying. They usually use light to medium thickness coatings such as stains, varnishes, enamels, and latex paints, or slightly thicker coatings such as thin putty, epoxy paint, and anti-corrosion paint. If you also have such needs and are still looking for an airless sprayer, now is the time.

Rongpeng R750 has a 5HP (3800W) motor and a maximum pressure of 3300 PSI to provide the necessary power. Low MoCr2 independent steel bushings are very wear-resistant and easy to clean. Low per minute 2000 unique inductive intelligent recognition nozzle technology, from water-based paint, latex paint to epoxy resin and thin putty and other coatings can help spray large projects uniformly, ships, factories, large building steel structures and housing surfaces to the greatest extent.

Key considerations when choosing an airless sprayer

Nozzle selection
The nozzle is one of the most critical components affecting the airless sprayer because it directly controls the spray pattern, atomization and material flow. The standard caliber of Rongpeng R750 is 0.025-inch nozzle, and the maximum supported nozzle size is 0.031-inch, which can flexibly meet various project requirements. Generally speaking, smaller nozzles are used for light to medium-weight coatings such as latex, stains and varnishes, while larger nozzles are used for heavier coatings such as primers and block fillers.

Flow rate and throughput
The flow rate determines how much paint the sprayer can spray per minute, which is critical for large projects. The 6L/min flow rate of Rongpeng R750 makes it a high-capacity machine that can handle large jobs efficiently. Large throughput is especially beneficial for contractors who need to cover large areas quickly.

Pressure and Horsepower
Pressure is another key factor as it determines the sprayer’s ability to atomize paint into a fine mist. The Rongpeng R750 has a maximum pressure of 3300 PSI, which combined with its 5HP motor ensures that it can handle the thickest coatings, such as anti-corrosion materials and thin putty.

Hose Length and Mobility
The length of the high-pressure hose directly affects the operating range and convenience of the sprayer. The RONGPENG R750 is equipped with a 30-meter high-pressure hose, which allows it to work flexibly in a large space without constantly repositioning the power unit. This extended range is especially useful for large-scale spraying, such as spraying multi-story buildings or large outdoor structures.

If you have an airless spray machine. To protect the sprayer and extend its service life, make sure to use a filter to filter the paint, which can effectively prevent clogging.
