Pihustit

Pihusti (pihustit as plural) is a device or system that disperses liquids into a fine mist or spray. In Finnish usage it covers consumer spray bottles, garden sprayers, and industrial spraying equipment. Pihustit are used to apply liquids such as water, pesticides, disinfectants, cleaners, fragrances, and coatings.

A typical pihusti consists of a reservoir, a pump or pressurized chamber, a nozzle, and an atomization mechanism. Liquid is forced through the nozzle and broken into droplets. Droplet size and spray pattern depend on nozzle design, pressure, and flow rate.

Types include manual pump sprayers (squeeze bottles), compressions sprayers, backpack sprayers, and battery-powered sprayers. In coating or painting contexts, analogous devices are spray guns or air-assisted sprayers, with terminology varying by region.

Safety and environmental considerations include avoiding drift, using appropriate personal protective equipment, calibrating dosage, and following label instructions for any chemicals. Cleaning, storage, and disposal of residues and containers are important to prevent contamination.

History and development: Spraying devices evolved from simple bottles to sophisticated pressurized systems during the 19th and 20th centuries, enabling broader use in agriculture, sanitation, and industry.
