Compared with hydraulic spray nozzles, also known as single-fluid nozzles, which spray liquid by pressurizing it with a pump, pneumatic spray nozzles can <span style=\"font-weight:bold\">produce finer mist<\/span> and are well suited to <span style=\"font-weight:bold\">low-volume moisture application<\/span>.\n<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n        <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/09\/nozzle-paper-002-image_4.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n    <\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">In dry conditions, corrugated-board base paper loses moisture and shrinks, increasing the risk of warping.
