The RECTORSEALA2904530X30 A2904530X30 is an aluminum fixed-bar return air filter grille designed for sidewall or ceiling installations in residential ventilation systems. Part of the A290-45 series, this grille features fins set at a 45-degree angle to promote consistent airflow distribution across the opening. The unit measures 30 inches by 30 inches, making it suited for larger return air openings. It ships with a white powder coat finish that blends with standard interior wall and ceiling finishes. HVAC technicians and mechanical contractors typically install this grille as part of a ducted forced-air return system.
This grille is intended for use in residential ducted HVAC systems where a fixed-bar return air grille is specified for a sidewall or ceiling opening. The 30 by 30 inch size fits larger return air rough openings and is appropriate for central air systems in homes or light commercial spaces where return airflow capacity is a priority. No moving parts or damper blades are included, as this is a fixed-bar design.
Designed as an OEM-style fixed-bar return air filter grille for residential and light commercial ducted HVAC systems requiring a 30 by 30 inch sidewall or ceiling return air opening.
Installation is typically performed by a licensed HVAC technician or mechanical contractor. Power down the air handling unit at the disconnect before removing or installing any grille in the return air pathway. Secure the grille to the surrounding duct or wall framing using the appropriate fasteners for the substrate. Verify the rough opening dimensions match the grille size before installation to ensure a proper fit and seal.
