AJ Manufacturing produces custom and standard stainless steel and aluminum air distribution products purpose-built for critical and sterile environments — hospitals, laboratories, and commercial buildings where air quality and contamination control can't be compromised. 

Their product range spans supply and return grilles, ceiling diffusers (perimeter slot, flat radial, hinged radial, and laminar flow), fan filter units, and HEPA-filtration equipment engineered for operating rooms and cleanrooms. 

Built from 304/316 stainless steel with made-to-order finishes, their equipment integrates built-in LED lighting options into clean-air ceiling systems, giving facilities a single modular solution for air distribution, filtration, and lighting in spaces where sanitation and precise airflow control are non-negotiable.
