American Metal Products 3018W18 Baseboard Diffuser 18 in

Product Description

The AMERICAN METAL PRODUCTS 3018W18 is a perimeter baseboard diffuser designed to distribute conditioned air along the base of exterior walls in residential and light commercial HVAC applications. Constructed from painted stamped steel with a white finish, this diffuser features a sunburst pattern face with 1/3 inch fin spacing and a 3 inch base extension. At 18 inches in length, it mounts flush at floor level to deliver horizontal airflow across the room, minimizing cold spots near exterior walls. HVAC installers and sheet metal contractors specify this type of diffuser for hydronic and forced-air perimeter heating systems where low-profile, aesthetically clean terminations are required.

This baseboard diffuser is suited for perimeter-style supply air applications in residential new construction and retrofit projects. It is typically installed at the base of exterior walls to counteract heat loss through windows and exterior surfaces. The sunburst pattern and white painted finish make it a common choice where the diffuser will remain visible after installation. It is sold in packages of 12 units, making it practical for multi-room or multi-unit projects.

Key Features

• Sunburst pattern face for wide, even horizontal air distribution
• 1/3 inch fin spacing for controlled airflow direction
• 3 inch base extension for proper perimeter wall fitment
• Painted stamped steel construction for durability and consistent finish
• White finish blends with standard baseboard and wall trim
• Sold in packages of 12 units for project-quantity purchasing

Compatibility

Designed as an OEM-style replacement or new-installation perimeter baseboard diffuser for residential and light commercial forced-air supply duct terminations at floor level along exterior walls.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Shut off the air handler or furnace before cutting into existing ductwork or repositioning an existing diffuser. Secure the diffuser to the duct boot using appropriate sheet metal fasteners, ensuring the face sits flush against the finished floor and wall surface. Local mechanical codes should be consulted for required clearances and fastening methods.
