United McGill

What United McGill does

United McGill Corporation is a family-owned industrial engineering and manufacturing company founded in 1951 in Columbus, Ohio, currently headquartered in Groveport, Ohio. The company operates five wholly-owned subsidiaries — McGill AirClean (air pollution control equipment including electrostatic precipitators, fabric filters, scrubbers, and regenerative thermal oxidizers), McGill AirFlow (commercial and industrial HVAC sheet metal ductwork and the Duct Express fulfillment service), McGill AirPressure (autoclaves and vacuum dryers), McGill AirSilence (noise control solutions), and McGill AirSeal (HVAC sealants and adhesives) — each operating its own manufacturing plant and sales engineering offices.

The company generates revenue primarily through one-time engineered system sales and construction product distribution, with project sizes ranging from approximately $1,000 to over $10 million. Customers span aerospace (Boeing, Lockheed Martin, NASA), automotive (Ford, GM, Goodyear), pharmaceutical (Pfizer, Eli Lilly, Merck), chemical (DuPont, P&G), glass (Corning, Owens-Illinois), pulp and paper (Georgia-Pacific, International Paper), and several thousand HVAC sheet metal and mechanical contractors. Distribution is conducted exclusively through direct sales engineering offices, with no digital channels identified, and products are sold throughout North America (all 50 US states and Canada) supplemented by technology licensing agreements outside the U.S.

The business employs approximately 150 Associates and reports annual sales of approximately $30 million. Manufacturing is concentrated in Ohio and four other states (Iowa, South Carolina, Texas, Vermont), with no external institutional investors, no funding rounds, and no parent company. The go-to-market is enterprise field sales supplemented by the Duct Express small-ticket fulfillment service; pricing is project-based and not publicly disclosed. United McGill's competitive position is built on 75 years of continuous operation, pioneering spiral duct technology (1950s), multi-decade domain expertise in air pollution control, and a diversified product portfolio that allows cross-selling across air quality, HVAC, pressure processing, noise control, and sealing categories.

Broad incumbents

• FLSmidth: Supplier of equipment and services to mining, cement, and process industries, including air pollution control and filtration systems. Comparable to McGill AirClean's industrial process APC business in cement, lime, and refractory kiln markets, though at substantially larger scale and broader scope.
• SPX Technologies: Diversified industrial manufacturer with HVAC and detection/measurement businesses serving commercial and industrial customers. Overlaps with United McGill's HVAC ductwork and air handling offerings through a much broader product portfolio and global footprint.
• Carrier Global: Global leader in HVAC, refrigeration, and building automation with a broad commercial/industrial product portfolio. Comparable as a major commercial HVAC equipment manufacturer; United McGill sells into the same commercial construction channel as Carrier's downstream contractors.
• Trane Technologies: Global HVAC and building solutions provider for commercial, industrial, and institutional customers. Comparable at the system/contractor level — Trane's commercial HVAC systems are installed using ductwork and accessories similar to McGill AirFlow's product lines.

Direct peers

• Donaldson Company: Diversified industrial filtration manufacturer providing air pollution control, dust collection, and industrial air filtration systems across similar end-markets (manufacturing, aerospace, chemical). Comparable as a North American filtration/APC equipment OEM with a broader product portfolio and substantially larger scale.
• Hamon: Global supplier of air pollution control, cooling, and heat transfer equipment for power and industrial customers, including electrostatic precipitators, fabric filters, and scrubbers. Comparable as an industrial APC OEM with overlapping technology portfolio and similar project-based engineering model.
• CECO Environmental: Provider of air pollution control, industrial ventilation, and noise control solutions including dampers, scrubbers, and acoustic products. Directly comparable to McGill AirClean and McGill AirSilence as a focused APC/acoustic equipment manufacturer serving industrial and process customers.
• Babcock & Wilcox: Supplier of environmental and steam generation systems for coal-fired, biomass, and waste-to-energy plants, including electrostatic precipitators, fabric filters, and scrubbers. Directly comparable to McGill AirClean's electrostatic precipitator and APC business in the boiler and power/process industry verticals.
• BWF Envirotec: European-based manufacturer of industrial fabric filter media and complete baghouse/fabric filter systems for industrial air pollution control. Comparable to United McGill's fabric filter product line within McGill AirClean, especially for incinerator and boiler applications.

Emerging players

• LS Industries: Manufacturer of industrial ovens, paint finishing systems, and environmental control equipment for metal processing and industrial customers. Partial overlap with United McGill's industrial processing and air-handling businesses in metal finishing and industrial process markets.
