A pressure piston is a mechanism that uses a piston system to create a constant and high pressure in the spray system. This type of pressurization is ideal for professional or commercial applications where sustained and stable pressure is needed for large-scale spraying jobs. The pressurized plunger is often used in sprayers for large gardens, agricultural applications or industrial applications where a strong and even spray over large areas is required. The plunger system offers high performance and is very efficient when applying chemical sprays or pesticides.
