What TAMCO does

TAMCO is a manufacturer of high-end aluminum dampers and air control products serving commercial, industrial, and institutional HVAC markets across North America. Founded in 1955 and headquartered in Smiths Falls, Ontario, with manufacturing operations in Smyrna, Tennessee, the company began developing its aluminum damper line in 1980 and has since built a portfolio spanning airfoil control dampers (Series 1000, 1500, 8800), UL/ULC-approved smoke dampers, thermally insulated and thermally broken frame dampers (Series 9000), medium- and heavy-duty backdraft dampers, face & bypass dampers, multizone dampers, insect screens, and a dedicated data center damper line. Core technology centers on all-aluminum construction, silicone jamb seals tested to over 2 million cycles and 20–30 year service life, pioneering thermal break technology, airfoil blade geometry delivering the industry's lowest pressure drop, and an in-house AMCA-certified test laboratory. The company holds ISO 9001 and ISO 27001 certifications.

TAMCO operates as a core brand within SPX Technologies' (NYSE: SPX) Engineered Air Movement (EAM) segment, alongside Cincinnati Fan, Strobic Air Technologies, and Daniels Fans. Revenue is generated through hardware sales of dampers and accessories, with pricing not publicly disclosed and delivered through a direct enterprise field-sales motion: a network of over 170 sales engineers located across 56 offices in the U.S. and Canada. Customer segments are horizontal — commercial real estate, water treatment, universities, data centers, and industrial facilities — with specification-driven, project-based selling rather than disclosed anchor accounts. Recent product launches (AeroV vertical blade backdraft damper and Motor Mounting Kits in 2025; dedicated Data Center Dampers in 2024) indicate active product development focused on adjacent applications and growing infrastructure verticals.

Product overview

Tamco is a manufacturer of high-end aluminum air control dampers and related products serving commercial, industrial, and institutional markets. The company was established in 1955 and began developing aluminum dampers in 1980. Tamco is part of SPX Technologies' Engineered Air Movement (EAM) business, along with Cincinnati Fan, Strobic Air Technologies, and Daniels Fans. The product portfolio includes multiple series of airfoil control dampers (Series 1000, 1500, 8800) for low to ultra-low leakage applications, UL/ULC approved smoke dampers (Series 1000 SM, 1000 SM-M) for fire and smoke containment, thermally insulated dampers (Series 9000) and thermally broken frame dampers (Series 9000 BF) for temperature-critical applications, medium-duty and heavy-duty backdraft dampers (Series 7000/7100/7600), face and bypass dampers (Series 1000 FB, 1500 FB, 9000 FB) for HVAC coil control, multizone dampers (Series 1000 MZ, 1001 MZ) for zoned airflow control, insect screens (Series 6000), and specialized data center dampers. The products share common design principles including all-aluminum construction, maintenance-free operation, silicone seals, and AMCA-certified performance testing. Tamco also offers a comprehensive range of accessories (motor mounting kits, jackshafts, linkage plates, blade position indicators) and configurable options (elevated temperature, severe cold, moisture resistance, salt water resistance) and profiles (standard, narrow, wide) to address specific application requirements.
