Plenum Grille Boxes

Plenum and grille boxes are essential components in HVAC systems, connecting ductwork to air vents, diffusers, or grilles to ensure controlled airflow into living or working spaces. They are widely used in residential, commercial, and industrial environments to regulate and diffuse air, enhancing comfort and air distribution. Available in configurations with top entry for vertical duct connections and side entry for horizontal connections, these boxes accommodate various design preferences and space constraints.

Constructed from materials such as metal and plastic, plenum and grille boxes cater to different installation needs and environmental conditions. Metal boxes, typically made of galvanised steel or aluminium, offer durability and strength, making them suitable for high-pressure and high-temperature environments. In contrast, plastic boxes, often composed of HDPE or PVC, are lightweight and corrosion-resistant, ideal for residential settings or areas with high moisture levels. Choosing the right plenum or grille box involves considering ductwork layout, HVAC system requirements, and environmental factors to ensure optimal performance and efficiency for your project.
