Product Lines
FD-Series Foil Flex Dryer Ducts
The FD-Series is Lambro Industries' line of flexible aluminum foil dryer duct for residential dryer exhaust venting. FD-Series flexible duct provides the connection between the dryer's rear exhaust port and the wall connection point, accommodating short runs and offset connections where rigid duct can't make the transition. Flexible dryer duct is intended for the short connector section, not for extended runs where semi-rigid or rigid metal duct is required.
DL-Series Semi-Rigid Aluminum Dryer Ducts
The DL-Series is Lambro Industries' semi-rigid aluminum duct product line, rated for maximum operating temperatures up to 400°F and appropriate for extended dryer exhaust duct runs where code requires non-combustible metal duct. DL-Series semi-rigid ducts can be shaped to navigate corners and offsets while maintaining the smooth interior surface that reduces lint accumulation and airflow restriction. Where FD-Series handles short connector sections, DL-Series is the Lambro specification for the main duct run.
AWV and GWV-Series Wall Vents and Exhaust Hoods
The AWV and GWV-Series are Lambro Industries' wall vent and exhaust hood lines for dryer, bathroom, and kitchen exhaust terminations through exterior walls. These products are available in plastic and metal construction, with damper configurations that close when the exhaust fan or dryer is not operating to prevent outdoor air, pests, and moisture infiltration.
ARV and PRV-Series Roof Vents
The ARV and PRV-Series are Lambro Industries' roof vent product lines for dryer and bathroom exhaust systems that terminate through the roof deck rather than an exterior wall. ARV and PRV-Series roof vents provide a weatherproof termination point with damper configurations to prevent back-drafting when the system is not in use.
AC-Series Air Connectors
The AC-Series is Lambro Industries' UL 181 Class 1-certified flexible air connector line for HVAC supply and return duct connections in residential forced-air systems. AC-Series air connectors are specified for short connector runs between the main duct trunk and the register boot, providing the flexibility needed to align differing duct center-to-center dimensions.
