NAICS 333413: Industrial and Commercial Fan and Blower and Air Purification Equipment Manufacturing — Federal Contracts

What NAICS 333413 covers

The North American Industry Classification System (NAICS) is the standard the federal government uses to classify the industry of every contractor and every procurement. NAICS 333413 identifies businesses primarily engaged in industrial and commercial fan and blower and air purification equipment manufacturing. When a contracting officer publishes a solicitation on SAM.gov, they tag it with the NAICS code that best matches the work — which is why getting your NAICS portfolio right inside SAM is the single most important step for showing up in agency searches.
