Spraylers

A sprayler is a device designed to release liquids in a fine spray for applications such as surface coating, irrigation, or humidification. The term is not as standardized as sprayer or sprinkler and can refer to a range of nozzle assemblies used in agriculture, horticulture, industry, or consumer products. In irrigation and gardening, spraylers are often called spray nozzles or spray heads.

Most spraylers consist of a nozzle body orifice, a connection to a fluid supply, and a mechanism to regulate flow and pressure. They operate under pressure generated by a pump, gravity feed, or compressed air. The design of the orifice and the operating pressure determine the spray pattern (cone, fan, or jet) and the droplet size, which influence coverage, drift potential, and application efficiency.

Common applications include applying pesticides, herbicides, or fertilizers in farming; distributing humidity or cooling in greenhouses; and coating, cleaning, or heat transfer in industrial processes. Household spray bottles and garden sprayers are small-scale examples of spraylers used for domestic tasks and plant care.

Important selection considerations include material compatibility with the liquid, corrosion resistance, flow rate, spray angle, and droplet size distribution, as well as ease of cleaning and maintenance. Safety and regulatory concerns focus on correct use, minimizing drift or overspray, and ensuring proper handling of chemicals in accordance with local guidelines and product labels.
