Pressure loss curve 

The universal roof duct UDF made by CasaFan is designed specifically for handling supply and exhaust air in all ventilation systems with a wide open cross-sectional area and low pressure loss. It is made of weatherproof galvanised steel sheet. On top of that the openings for the air circulation are equipped with bird screens. The roof mounted air outlet/inlet is suitable for installation on ventilation pipes with standard sizes: Currently, seven models with a diameter ranging from 125mm to 400mm are available in our creoven online shop. Another plus: All models are available with a slate-grey or a brick-red cowling to match the roof.

The UDF series can be mounted to any flat or gabled roof without any problems. No matter what type and shape the tiles come in, this roof duct is mounted easily to many different kinds of building materials on-site. A wide circumferential, rolled lead belt withstands storm, heavy rain and seasonal variations in temperature. The detailed dimensions of each size is listed in the chart, the diagram shows the different data about airflow and pressure loss.
