The NAPT is a circular supply air diffuser featuring a perforated front plate and a back section with a spigot air connection. Due to its efficient ventilation properties, the NAPT is suitable for a wide range of applications. Designed for ceiling mounting, the diffuser can be directly installed into an air duct system or connected to a TK or TLM commissioning box. This setup ensures uniform and balanced airflow to the diffuser. The maximum recommended temperature difference (Δt) for optimal performance is 10 °C.
The NAPT diffuser is best suited for comfort environments, such as offices, schools, hospitals, restaurants and retail stores.

The perforated NAPT front diffuser plate is made of galvanized steel, the back section is made of sheet steel. The air connection features an EPDM rubber sealing. The diffuser is powder coated in standard RAL 9003 white color.
TK: The NAPT can be mounted in the TK commissioning box, featuring environment friendly sound absorbent insulation, a supply air distribution plate and a removable damper module for commissioning and measuring of the airflow. The low build height is possible by the internal socket design of the diffuser connection, minimising the total height of the diffuser and box.
TLM: A compact commissiong box for airflow regulation with supply air diffusers. The product is designed for ceiling installation and ideal for flush mounting in suspended (false) ceilings. The TLM commissioning box is recommended for applications, where there is a requirement for a low noise level performance.
