Air Distribution Terminals

Return air grilles are divided into louver-face and mesh-face designs, in aluminium, stainless steel or treated mesh. The square model is classified separately by function as an exhaust air grille.

Construction & specifications

Grille and plenum box assembly

A complete terminal combines a visible room-side grille with a concealed plenum box and duct connection. Each unit shown includes a medium-efficiency filter behind the face; the treated-mesh return air inlet also has an air-flange connection.

Project coordination: Airflow direction, volume, filtration grade, pressure-control accessories and connection geometry must all be settled by the project HVAC design and the standards that apply to the facility. Terminals are scheduled against that design, not the other way round.

FAQ

Frequently asked questions

What is the difference between a return air grille and an exhaust air grille?

A return air grille collects room air and sends it back to the air-handling unit for recirculation. An exhaust air grille removes air from the room and sends it outdoors or to a designated exhaust system. They can look identical, so selection follows the duct it connects to, not the face pattern.

Why choose a treated mesh face over a standard louver face?

The treated high-resistance mesh carries a coating intended to reduce static build-up and dust adhesion, which suits areas where cleaning intervals are long or airborne particulate is a concern. Standard louver faces are the general-purpose choice and are easier to match to neighbouring finishes.

Are the plenum box and filter included with the grille?

Yes. Each terminal shown ships as an assembly — the room-side face, the steel-sheet plenum box, a medium-efficiency filter and black mesh behind the face. Duct connection geometry is matched to your HVAC drawing.
