AJ Manufacturing produces some of the world’s best commercial stainless steel HVAC products, specifically designed for sterile environments. Lean, just-in-time manufacturing produces custom and standard air distribution components made of 304 or 316 stainless steel and aluminum, for hospitals, laboratories, and commercial buildings. Our proven HEPA filtration technology keeps the air you breathe free of airborne pathogens, delivering purified air to a room or removing contaminated air. Our manufacturing process for products like diffusers, ceiling systems, fan filter units, air extractors, plenums, transitions, and more, is absolutely critical in environments that should remain sanitary and clean, or in buildings where ventilation and air distribution are key. There’s no room for error when it comes to clean and efficient air distribution; we work toward perfection throughout each step of our manufacturing process.
