What Airmo does

Airmo Inc. Pressure Technologies is a Minneapolis-based, family-owned manufacturer of patented high-pressure hydraulic technologies for tube and pipe testing, forming, and expansion. Founded in 1946 by George A. Smida and John Rodgers and now led by third-generation President Chuck Smida, the company designs and builds equipment rated for working pressures up to 60,000 psi (4,137 bar) from a 14,000-square-foot engineering and manufacturing facility in Coon Rapids, Minnesota. Its product portfolio is organized into four sub-brands: TestMaster® (hydrostatic test tools, hydraulic power supplies, burst test chambers), SelectForm® (tube end forming tools and multi-station systems), ExpanTek® (ball and hydro tube expansion systems), and NuQuip® (high-pressure accessories including pumps, valves, quick disconnects, regulators, hoses, and accumulators). The portfolio also includes a replacement parts and service plan business.

The company's revenue model is B2B capital equipment sales plus aftermarket service. Products are configured to customer specifications (pressure rating, tube size, control options) and sold through a direct sales model with quote-based pricing, supported by phone, email, and website quote-request workflows; no public pricing is disclosed. Service plans are sold on multi-year contracts with pricing tied to tool OD size and pressure rating. Go-to-market combines a digital product literature portal, social media (LinkedIn, X, YouTube), industry trade shows, and direct technical consultation. Distribution is direct to end users with no intermediaries indicated.

Airmo serves enterprise and mid-market manufacturers across aerospace, defense, subsea oil and gas, HVAC and refrigeration, tube and pipe manufacturing, and transportation, with documented customers including major space exploration companies and medical cylinder manufacturers. The company reports it supplied test tools to all five lead contractors on NASA's Artemis II crewed lunar mission and serves 12 of the top 20 global space exploration companies. A 2025 milestone of record sales, combined with 80 years of continuous operation and a small headcount of 1–10 employees, indicates an exceptionally capital-light, high-margin specialty industrial model built on proprietary patented technology and deep domain expertise rather than scale.
