Industry Overview
Industrial & Commercial Fans & Blowers & Air Purifing Equip
SIC 3564 covers makers of industrial and commercial fans, blowers, and air purifying equipment that move, filter, and condition air for factories, data centers, healthcare facilities, cleanrooms, commercial buildings, and food and pharma plants; typical customers include OEMs, HVAC contractors, and end users retrofitting for energy and indoor air quality goals. Core offerings span axial and centrifugal fans, variable-speed blowers, HEPA and activated carbon systems, UV-C disinfection units, and smart controls with IoT monitoring. Key risks involve volatile steel and electronics supply chains, tariff exposure, compliance with OSHA airflow/noise limits, EPA and DOE efficiency rules, UL/NFPA safety standards, and evolving building codes. For 2024-2025, demand is driven by data center cooling tied to AI workloads, tighter IAQ expectations, electrification and heat-recovery retrofits, and predictive maintenance using sensors and analytics, while buyers press for lower lifecycle costs and documented ESG benefits.
