30x17cm Grate Fitting for 125mm Tube | Reference ALI_EMB 30-125

The 30x17 cm grille inlet with a 125 mm duct connection is an essential component in any HVAC, air conditioning, or forced ventilation system. This adapter allows for a tight and efficient transition between rectangular grilles (whether fixed or adjustable) and 125 mm diameter circular air ducts.

Made from high-strength materials, this component ensures low pressure drop and constant airflow, optimizing the performance of your air conditioning unit or extraction system. Its design facilitates installation in false ceilings, walls, or exposed ducts, guaranteeing a perfect fit that prevents air leaks and unnecessary noise.

Main Product Features

• Universal Compatibility: Designed specifically for grilles with nominal dimensions of 300x170 mm, for both supply and return models.


• Duct Connection: Circular rear opening adapted for flexible or rigid ducts of 125 mm diameter.


• Durable Material: Constructed of high-quality galvanized steel, which gives it excellent corrosion resistance and a long service life in indoor environments.


• Flow Optimization: Its internal geometry is designed to minimize turbulence, allowing for quieter and more efficient air distribution.


• Product Reference: ALI_EMB 30-125.


• Easy Installation: Allows for quick assembly using mechanical fixing or standard sealing in the air conditioning sector.

Advantages of use in Air Conditioning and Ventilation

Using the correct duct inlet is key to maintaining the energy efficiency of your home or business. By ensuring a tight connection between the duct and the grille, pressure losses that force the system to work harder are eliminated. It's the ideal solution for domestic ducted air conditioning installations and controlled mechanical ventilation (CMV) systems.
