Lambro Industries 606B-MLS 6 Inch Louvered Fresh Air Intake Vent

Product Description

The LAMBRO INDUSTRIES 606B-MLS is a 6-inch fresh air intake mini louvered vent designed for residential ventilation applications. Constructed from brown plastic with an integrated metal bug screen, this vent allows outside air to enter a structure while blocking insects and debris. The mini louver design provides directional airflow control and sheds water away from the opening. HVAC technicians and general contractors typically install this vent as part of a combustion air or ventilation air intake system. The brown finish blends with standard exterior siding and trim.

This vent is suited for residential construction and retrofit ventilation projects where a low-profile, exterior-mounted fresh air intake is required. It is commonly installed through exterior walls to supply combustion air to gas appliances, to ventilate crawl spaces, or to serve mechanical ventilation systems. The metal bug screen helps maintain airflow integrity while preventing pest intrusion at the duct termination point.

Key Features

• 6-inch opening sized for standard residential intake ductwork
• Brown plastic construction resists corrosion and UV exposure
• Mini louver design provides directional airflow and passive water shedding
• Integrated metal bug screen blocks insects and coarse debris
• Low-profile exterior profile suitable for through-wall installation

Compatibility

Designed as an OEM-style replacement or new-installation fresh air intake vent for 6-inch residential ventilation and combustion air intake duct terminations.

Installation Notes

This vent is typically installed by HVAC technicians or general contractors during new construction or retrofit ventilation work. Shut off any associated mechanical ventilation equipment before cutting the wall penetration or disturbing the duct connection. Follow local building codes and IFGC requirements for combustion air intake termination locations, including minimum clearances from grade, openings, and ignition sources. Seal the exterior flange to the wall surface with an appropriate weatherproof caulk to prevent moisture intrusion.
