The Industry Leader in Custom and Standard Stainless Steel Air Distribution Products

Since 1924, AJ Manufacturing has specialized in made-to-order air outlets for critical environments. Sophisticated equipment, the latest technology, and expert engineers who overcome even the toughest jobsite challenges result in fast turnaround on your project. Each piece of your system is designed and built with a focus on quality, precision, and efficiency.

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.
