Air intake grill ALNOR USAV-200 — aluminum construction, circular duct connection

ALNOR USAV-200 is an aluminum air intake grill designed for HVAC systems with circular duct connections. The unit offers a corrosion-resistant inlet for fresh air or supply air distribution and is suitable for integration with air handling units and round ductwork in residential and commercial ventilation installations. Its simple circular connection and lightweight aluminum construction make it a practical choice where durability and compatibility with round ducts are required.

Advantages

The aluminum construction provides good resistance to corrosion while keeping the weight low for easier handling and installation. The circular duct connection ensures a secure fit with round ducts and standard ventilation components. The grill’s design supports efficient air intake with minimal obstruction, and the plain finish allows compatibility with a variety of installation environments.

Suitable for

• Fresh air intake to air handling units
• Supply air connections in residential ventilation systems
• Commercial ventilation installations with round ducts
• Replacement or retrofit projects requiring an aluminum circular inlet

Key specifications

• Material: aluminum
• Connection type: circular duct connection
• Application: intake for fresh or supply air in ventilation systems
• Mounting: designed for integration with round ductwork and compatible fittings
• Finish: plain/aluminum surface suitable for painting or covering if required

How to use

Install the grill at the intended intake location and secure it to the ductwork or mounting frame following standard ventilation installation practices. Ensure the circular connection is properly seated and sealed to prevent air leaks. Check alignment with the connected duct and air handling unit, then fasten with appropriate clamps, screws, or sealants as required by the installation environment. Perform an airflow test and inspect for gaps after installation.

Usage recommendations

Regularly inspect the intake grill for accumulation of dirt, debris, or corrosion. Clean the surface with a soft brush or damp cloth; avoid abrasive cleaners that could damage the aluminum finish. Ensure sealing and attachment points remain secure to maintain system efficiency and reduce the risk of infiltration.
