Deep pleated rigid box filters set the benchmark for commercial and industrial air filtration, featuring a deep pleated design that maximizes surface area while maintaining a compact profile. This construction enables superior particulate capture without restricting airflow, ensuring efficient operation. Built with robust frames of galvanized mild steel, stainless steel, or aluminum, these filters endure continuous use in demanding settings. The filtration media, including high-quality glass fiber or non-woven felt, is supported by stainless steel or aluminum separators that preserve pleat integrity under pressure fluctuations. With efficiency ratings from F5 (40-45%) to F8 (90-95%) per EN 779:2002 standards and EU5 to EU8 under Eurovent 4/5, they deliver reliable performance across a wide range of applications.
