Duravent Group, a Detroit-headquartered leader in the venting and air movement industries with roots tracing to 1901, announced on March 18, 2026 that it has secured a significant strategic growth investment from Bain Capital. Bain Capital will partner with Duravent's leadership team — led by President and CEO Simon A. Davis — and existing investor Egeria to accelerate the company's next phase of growth, deepen its category leadership, and expand its platform through both organic investments and strategic acquisitions.

Duravent Group unifies 14 established and respected brands that collectively make up one of the most comprehensive venting and air quality product portfolios in the HVAC industry: Duravent, Hart & Cooley, Selkirk, AirMate, AmeriFlow, Amerivent, AMPCO, Heatfab, Lima, Milcor, PortalsPlus, RPS, and Security Chimneys — a portfolio that touches virtually every venting application in residential and commercial HVAC, from pellet stove flue systems to commercial kitchen ventilation.

Who Is Duravent Group?

Duravent Group is North America's largest provider of venting solutions and air quality products, with a manufacturing and distribution footprint spanning the United States, Canada, and Mexico. The company's heritage goes back more than 125 years — predating the modern HVAC industry itself — through predecessor companies that established the technical standards for venting systems that are still foundational to building codes today.

Matt Evans, a partner at Bain Capital Special Situations, characterised the investment thesis: 'With a market-leading platform in the venting, filtration, and air quality industries and a more than 100-year legacy of engineering excellence, Duravent is renowned for delivering the most reliable, cutting-edge HVAC systems for homeowners, contractors, and industry professionals. Simon and his team have done an impressive job of deepening the company's value proposition rooted in a customer-first mentality.'

Bain Capital's March 18, 2026 strategic growth investment in Duravent Group — a Detroit-based company unifying 14 HVAC venting brands with heritage tracing to 1901 — partners Bain alongside existing investor Egeria and CEO Simon A. Davis to accelerate organic growth and strategic acquisitions in the North American venting and air quality market.

The Venting Market Context — Why Bain Sees Opportunity

Venting is one of the most structurally important but least glamorised segments of the HVAC supply chain. Every gas furnace, boiler, water heater, and fireplaces requires a venting system — and the requirements for those systems are becoming more complex as the HVAC industry evolves:

• High-efficiency condensing equipment: Modern 90-plus percent AFUE furnaces and condensing boilers produce cooler, wetter flue gases that require polymer or corrosion-resistant venting materials rather than the single-wall metal flue systems that served older equipment. Duravent's broad material portfolio — galvanised steel, stainless steel, aluminium, and polymer systems — covers the full range.

• Heat pump and electrification growth: As heat pumps displace gas heating, the venting market shifts — fewer gas flue applications but more fresh air intake, ERV/HRV ventilation, and exhaust systems. Duravent's air movement product portfolio positions it in the ventilation growth segment that benefits from electrification.

• Indoor air quality: The post-pandemic IAQ awareness that has driven growth in air purification, filtration, and ventilation also benefits Duravent's air quality product categories.

The Bain Capital Special Situations Angle

The Bain Capital Special Situations group — rather than Bain's traditional buyout fund — made this investment. The Special Situations group targets complex, value-creation opportunities that require creative capital structuring alongside the operational expertise that Bain's private equity platform provides. The involvement of Special Situations rather than the core buyout fund may reflect the specific capital structure of the Duravent-Egeria existing relationship, which is characterised as an 'Evergreen investment approach to remain invested in companies over the long term.'
