Square Plaque Diffuser The Square Plaque Diffuser (SPD) has a flush appearance, making it ideal for architecturally-conscience commercial spaces, and provides industry-leading low pressure drop and sound generation with a 360° radial, horizontal air pattern for rapid mixing and optimal thermal comfort.

This versatile diffuser is easy to maintain, with little to no ceiling smudging and a tool-free removable face for quick access to dampers, accessories, and ductwork. The SPD is compatible with a wide variety of ceiling systems, and is designed to deliver architectural appeal without sacrificing performance. The SPD is an excellent choice for VAV applications, providing a tight, horizontal airflow pattern, even at low air volumes. Steel (SPD) - Standard Aluminum (SPD-A) - Optional
