psprøyte

psprøyte is a device used to apply liquids as a spray. It ranges from small handheld models used in home gardening to larger backpack or knapsack sprayers used in agriculture, cleaning, and sanitation. Operation relies on pressurizing liquid inside a tank so that liquid is expelled through a nozzle as a spray.

A typical psprøyte consists of a tank, a pump or electric pump to generate pressure, a hose and wand, and a nozzle. The nozzle can usually be adjusted to produce a fine mist or a coarser jet. Many models include features such as a pressure relief valve, a filter, and chemical-resistant seals to handle different liquids. Normal working pressures for consumer sprayers are around 1 to 3 bar (15 to 45 psi); professional models may operate at higher pressures.

Common liquids applied with psprøyter include plant protection products like pesticides and fungicides, fertilizers, disinfectants, and cleaning solutions. Nozzle selection affects droplet size and drift, which is important for effective application and minimizing environmental impact. Types of psprøyte include handheld trigger sprayers, pistol-grip pump sprayers, and larger backpack or knapsack sprayers, as well as cordless electric variants for larger areas.

Safety and maintenance are important. Users should wear appropriate personal protective equipment, keep liquids separate and clearly labeled, and avoid spray drift onto people, animals, or waterways. After use, rinse or flush the system with clean water, clean the nozzle, inspect seals, and relieve pressure before opening. Store emptied and cleaned sprayers in a cool, dry place away from direct sunlight.
