sprayar

Sprayar is a term used in some languages to denote a device that discharges liquids as a fine spray. It is commonly a loanword from English "sprayer" and may be used to refer to manual pump sprayers, compressed air sprayers, or electric sprayers. Sprayar devices range from small hand-held spray bottles used for household cleaning to large backpack or tractor-mounted sprayers used in agriculture and landscaping, as well as airless or pneumatic paint sprayers employed in coatings and construction.

The design typically includes a tank or reservoir, a pump or air chamber to create pressure, a nozzle or spray head, and a trigger or switch to control flow. Some models include adjustable nozzles to vary spray patterns, filters, and pressure relief valves. Operation involves pressurizing the liquid inside the reservoir and releasing it through the nozzle, which atomizes the liquid into droplets.

Common applications include applying water or fertilizers in gardening, applying pesticides in crop protection, cleaning and sanitizing surfaces, coating or painting small or large areas, and humidification through misting systems. Safety considerations emphasize using the correct chemical compatibility with materials, wearing protective equipment, avoiding inhalation of aerosols, and proper storage and disposal of containers and residues.

Etymology varies by language; in many languages sprayar is a loanword from English or a native adaptation. The term broadly covers devices designed to deliver liquid sprays rather than a single specific model.
