NAICS 333912 – Air and Gas Compressor Manufacturing encompasses the design, fabrication, and assembly of industrial-grade air and gas compression systems, including reciprocating, rotary screw, centrifugal, and scroll compressors, along with associated controls, filtration, and drying equipment. These systems are critical for pneumatic actuation, gas storage, pressure testing, and life support applications in defense, aerospace, medical, and laboratory environments. In government contracting, this sector supports mission-critical infrastructure requiring high-reliability, corrosion-resistant, and explosion-proof compressor units compliant with MIL-STD and ASME standards. Products in this NAICS often integrate with broader environmental control, fuel handling, and emergency response systems, positioning compressor manufacturing as an essential enabler of operational readiness across federal agencies. Top contractors in this space include MGI, INC., J.P.L. COMPRESSOR SERVICE INC, ALLYANT, LLC, LINDE GAS & EQUIPMENT INC., and STARWIN INDUSTRIES, LLC, a mix of specialized small businesses and niche industrial service providers with deep expertise in custom compressor retrofitting, maintenance, and system integration. These firms often hold small business set-asides and compete for task orders requiring rapid deployment, field service support, and compliance with strict military and federal safety specifications. The Department of Veterans Affairs and the Department of Defense are the primary procuring agencies, leveraging compressor systems for medical gas delivery in VA hospitals, submarine and aircraft maintenance facilities, and hazardous material handling operations. The Department of Commerce also procures compressors for scientific research and calibration labs requiring ultra-pure gas environments. The competitive landscape is characterized by technical specialization over scale, with opportunities concentrated in maintenance contracts, replacement parts, and system upgrades rather than new-build procurements. Contractors with certified quality systems, NDT capabilities, and experience in hazardous environment compliance are best positioned to capture sustained demand.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 333912 work as a small business.

1,000 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
