What AJ Manufacturing does
AJ Manufacturing Co., Inc., founded in 1924 and headquartered in Kansas City, Missouri, is a privately held specialty manufacturer of custom and standard stainless steel and aluminum air distribution products for critical environments. The company's portfolio spans structural operating room ceiling systems (SS-CARES, SSLORS, OR-360), laminar flow HEPA/ULPA filter diffusers, ceiling-mounted and ducted fan filter units (Criti-Clean Ultra, SSDIL-FFU, AJ Ultrafan), HEPA/ULPA filters (99.99% at 0.3 microns / 99.995% at 0.12 microns), cleanroom ceiling grids (Micro-T), and a broad line of supply/return grilles, diffusers, dampers, and architectural grilles. Select FFUs integrate natively with BACnet and MODBUS building automation systems. Certifications include UL 900 Class I, Factory Mutual approval, and HCAI seismic certification, with product compliance to ASHRAE 170 for healthcare ventilation. The firm has 11–50 employees, is independently owned with no disclosed external funding, and reports a 100+ year operating history.
The company sells exclusively through a direct, consultative enterprise sales motion led by National Sales Director Amy VanWagner, with quote-based project pricing on made-to-order specifications (304/316 stainless steel, aluminum, custom dimensions, antimicrobial coatings, integrated LED lighting). Customers include healthcare systems (New York-Presbyterian, Walter Reed, St. Luke's Nampa, University of Kansas Hospital, Mackenzie Vaughan Hospital), pharmaceutical manufacturers (Amneal, McNeil, Baxter), semiconductor and aerospace firms (Boeing, Hewlett Packard, Saint Gobain, Ceva), and research and government institutions (National Cancer Institute, Johns Hopkins, UMKC). All fabrication occurs at the Kansas City facility; shipping is FOB Kansas City via UPS with international support.
Recent strategic direction is product-led expansion: OR-360 (Nov 2024) bundles turnkey OR design-build, Micro-T ceiling grid and AJ Ultrafan FFU (2024–2025) create a turnkey cleanroom ceiling bundle for semiconductor and biotech, and SSDIL-FFU (March 2026) extends the line into general indoor air quality for schools and offices. A 2026 flagship SS-CARES installation at New York-Presbyterian, executed with Weill Cornell Medicine and Columbia University, anchors an East Coast reference project. AJ operates on a single revenue stream (hardware sales on custom-engineered orders) with no disclosed recurring service, software, or filter-replacement subscription model.
