What Lambro does

Lambro Industries, Inc. is a privately held US manufacturer of HVAC ventilation components, founded in 1967 in Amityville, New York, and now operating from a 50,000 sq. ft. headquarters and production facility at 115 Albany Ave. The company designs, manufactures, assembles, and distributes over 270 metal and plastic ventilation products and HVAC components — with the broader catalog reported at 803 active SKUs across 25+ product series — for residential and light commercial applications. Core product families include Foil Flex Ducts (FD-SERIES), UL 181 Class 1 Air Connectors (AC-SERIES), UL 181 Class 0 Air Ducts (AD-SERIES), Semi-Rigid Ducts (DL-SERIES), Vinyl Ducts (PVC-SERIES), UL 2158A Clothes Dryer Transition Ducts (TD-SERIES), Aluminum and Plastic Roof Vents (ARV/PRV-SERIES), Galvanized Wall Vents (GWV-SERIES), Snap Lock Pipes (SL-SERIES), and Adjustable Elbows (AE-SERIES). Components are organized into consumer-facing category lines for dryer, bathroom, and kitchen venting, plus washing machine pans and fresh-air intake vents.

Underlying technology centers on sheet metal forming (aluminum, galvanized steel), plastics extrusion/injection (ABS, PVC), and multi-layer laminated flexible duct construction with steel wire helix reinforcement. Select SKUs carry safety-critical third-party certifications: UL 181 Class 0 (zero flame spread, zero smoke developed), UL 181 Class 1 (flame spread index ≤ 25, smoke developed index ≤ 50), and UL 2158A for dryer transition ducts — qualifications required for code-compliant residential construction.

Lambro operates a channel-only business model. The company does not sell direct to consumers; instead, products flow through an authorized US dealer network, big box home improvement retailers, hardware stores, wholesale distributors, and online channels including Amazon, with a "Where to Buy" dealer locator on lambro.net as the primary consumer touchpoint. Pricing is quote-based and not publicly disclosed, with a stated multi-year contract posture for B2B dealer accounts; sales are coordinated through [email protected] and a toll-free number. Customer base spans HVAC contractors, plumbers, electrical wholesalers, lumber yard buyers, and large-format retailers, with end users being homeowners and small-commercial building operators who purchase through these intermediaries. The company is 100% family-owned, with founder Edwin L. Berger having assumed sole ownership in 1986, and reports 101–250 employees.

Products and services

• Foil Flex Ducts (FD-SERIES) Flexible aluminum foil ducts made from layers of aluminum foil and steel wire helix, used in HVAC systems for kitchen exhausts, bathroom fans, and general air circulation in residential and commercial buildings.
• UL 181 Class 1 Air Connectors (AC-SERIES) Flexible, factory-made conduits for air transfer meeting UL 181 Class 1 standards (flame-spread index not over 25, smoke-developed index not over 50), composed of aluminum/polyester layers with fire-retardant adhesive and galvanized steel wire helix.
• UL 181 Class 0 Air Ducts (AD-SERIES) Flexible air ducts with zero Flame Spread Value and zero Smoke Developed Index, the highest UL 181 Class 0 rating, providing superior fire safety for residential and commercial HVAC air handling.
• Semi-Rigid Ducts (DL-SERIES) Flexible metal air ducts (typically aluminum) that can be bent to specific shapes and retain their shape, offering more durability and heat resistance than flexible foil ducts.
• Vinyl Ducts (PVC-SERIES) Flexible PVC hoses with steel wire helix for general ventilation and exhaust in residential applications such as bathroom fans or fresh air intakes.
• Aluminum Roof Vents (ARV-SERIES) Durable aluminum roof-mounted vent components used to vent air from buildings, preventing moisture and heat buildup, commonly used for bath fans, range hoods, and attic ventilation.
• Plastic Roof Vents (PRV-SERIES) Ventilation caps made of durable ABS plastic designed for installation on pitched, shingled roofs to expel moist air from dryers, bathroom, or kitchen exhaust fans.
• Galvanized Wall Vents (GWV-SERIES) Wall-mounted ventilation components made from galvanized steel, available in configurations including hood vents, dryer vent hoods, and bath fan vents.
• UL 2158A Clothes Dryer Transition Ducts (TD-SERIES) Short, flexible pipes connecting a dryer's exhaust port to main rigid ductwork, built with fire-resistant materials and meeting UL 2158A safety standards.
