The PLI is a square ceiling-mounted supply air diffuser designed for flush installation in modular false ceiling systems. It is intended for use in offices, schools, healthcare facilities, and other similar indoor environments where both discreet appearance and reliable performance are required. The diffuser features a circular front slot in combination with an aerodynamically shaped back connection section, enabling smooth 360-degree horizontal airflow. This design promotes even air distribution and efficient mixing with the room air. The airflow adheres to the ceiling surface (through the Coanda effect), reducing the risk of draughts in the occupied zone, even at lower airflows or when supplying cooler air.
The PLI maintains a uniform visible design regardless of spigot size and is suitable for both supply and extract air, without requiring modification. This ensures a consistent appearance across different areas of a building. The diffuser is connected to a TLM or TK commissioning box, which includes sound-absorbing insulation, an air deflector plate, and an integrated damper module with measuring tubes and cords for proper airflow adjustment. The PLI can handle temperature differences of up to 12 °C below room temperature, making it suitable for cooling applications while maintaining thermal comfort and air quality.
The PLI diffuser is ideal for ventilating spaces where discreet and efficient air distribution is required, such as offices, schools, hospitals, restaurant and retail stores. It is effective for both supply and extract air, making it versatile for various building types.
The front diffuser plate is made of galvanized steel, the back section is made of sheet steel. The unit is powder coated in
standard RAL 9003 white color. The air connection features an EPDM sealing.
