Polyaire Diffusion Fitting

The PDF is designed to split the airflow from the fan coil into 2, 3 or 4 separate ducts and allow ‘tuning’ of the flow from a central point which greatly reduces installation time.

The PDF also allows convenient fitment of motorized dampers and/or a Zone Control system with the main module attached to the PDF and motorized Dampers surrounding this. All components are in one place for ease of wiring and maintenance.

The outlets in the molding are clearly numbered to prevent confusion. Inlet dimensions come in either 350mm or 400mm diameter, while outlet dimensions range from 250mm to 300mm in diameter. The fitting is versatile, designed to accommodate 2, 3, or 4 outlets, each of which can be controlled through manual or electronic dampers compatible with Zonemaster systems. Its folded metal damper blades ensure extreme strength and pressure resistance. Duct fitting is facilitated through duct ties or draw bands. Please note that this product requires pre-ordering.

The PDF offers numerous advantages, saving considerable installation time while providing fully insulated, leak-proof fittings. It facilitates quick tuning of the system from a central point and allows for easy fitment of Zonemaster motorized damper systems. Furthermore, it decreases the chance of duct blow-off due to faulty taping and ensures easier, quicker, and more secure joining with cable ties. Additionally, ongoing maintenance is made easier with this solution.
