With the development of China’s coating market and the continuous improvement in the quality of coating equipment, these products have earned widespread recognition and praise from consumers. Below, we will introduce… Airless sprayer A detailed introduction to its superior performance.

　　 First, it has a wide range of applications.

　　Any paint suitable for air spraying can be used. Airless sprayer It cannot be used for high-viscosity paints or thick-film paints applied by air spraying; however, due to the high air‑spraying pressure, it can still be employed for spray application.

　2. High coating performance

　　Color tiles and steel spray guns can cover 3–5 square meters per minute, making them especially well suited for painting large areas and sizable objects. This significantly boosts labor productivity—10 times faster than manual painting and three times faster than air spraying.

　 3. Excellent coating quality

The high spray rate and strong penetration of the paint enhance the interfacial adhesion between the coating and the substrate. Moreover, when applying latex paint, steel coatings, or color-coated tiles, high-pressure airless spraying eliminates the adverse effects of moisture and particulate contaminants in the compressed air on coating quality, resulting in excellent adhesion and superior surface appearance.

Four , good coating performance

The paint mist deposition rate exceeds 85%, whereas conventional air spraying achieves only 60%. For substrates with complex geometries, the paint application process does not rely on compressed air flow, thereby eliminating the shielding effect that causes paint mist to accumulate in corner joints and other hard-to-reach areas due to airflow rebound, resulting in excellent coating performance.

　As the saying goes, a fine horse deserves a fine saddle. We provide you with top‑class airless spraying equipment, but did you know that using the right tools to maintain your equipment can significantly extend its lifespan and efficiency? The following sections will show you how to care for your airless sprayer and how to choose the appropriate maintenance tools.

　　 1. Maintenance Method for the Throat Seal Ring of an Airless Sprayer

　　The throat seal is a critical component of the spray plunger pump, designed to seal the gap between the piston rod and the cylinder liner. When worn, it can allow paint to leak into the oil cup.

　　Proper maintenance of the throat seal can significantly extend its service life. With each spray cycle, it is recommended to use a dedicated throat‑seal‑lubricating fluid (TSL) to service the equipment. The primary function of TSL is to prevent paint from adhering to the piston, thereby prolonging the lifespan of the throat seal. Solid Ruike TSL is a clear, specially formulated product that does not affect the spraying or application performance of paints.

　　2. How to maintain airless sprayers that will not be used for an extended period

　　So, how should you properly store an airless sprayer that won’t be used for an extended period? We recommend using pump‑protectant fluid. Its primary function is to fill the pump’s internal cavities, effectively preventing moisture from corroding the metal components.
