NORMAN FILTER COMPANY, L.L.C.

Norman Filter Company, L.L.C. specializes in the design, manufacturing, and supply of mission-critical filtration systems and fluid handling components for defense and industrial applications. Their core capabilities center on precision-engineered filter elements, air purification assemblies, and integrated fluid control systems, with deep expertise in high-efficiency particulate and contaminant removal technologies. The company produces custom-engineered components for aerospace, vehicular, and industrial environments, including gas turbine intake filters, hydraulic system strainers, and air filtration units compliant with stringent military performance standards. Their technical proficiency spans metallurgy, media fabrication, sealing technologies, and pressure-rated housing design, enabling reliable operation under extreme thermal, vibrational, and particulate loads. Differentiators include rapid prototyping of mission-specific configurations and adherence to military specification tolerances without reliance on commercial off-the-shelf solutions. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering mission-critical filtration components across multiple platforms including ground vehicles, aircraft systems, and fixed-site defense infrastructure. Their work supports sustainment, modernization, and field-deployed operational readiness initiatives, with recurring contracts for replacement and upgrade parts requiring exacting dimensional and material traceability. Industry focus is anchored in miscellaneous general-purpose machinery manufacturing (NAICS 333998), with complementary capabilities in industrial fan and blower systems (333413) and metal valve and fitting production (332919). This positions them as a niche supplier of integrated fluid and air management subsystems for defense-grade equipment, serving applications where contamination control is mission-essential. As a small business structured as a limited liability company based in Bridgeview, Illinois, Norman Filter Company operates without federal certifications but maintains a focused footprint in the defense supply chain through direct manufacturing and responsive logistics support tailored to military procurement cycles.
