Non-permeable material is used when heating with Prihoda fabric ducting so that all of the air exits the diffusers to travel to the occupied zone. Prihoda offers a range of diffusers which suit a large variety of applications.

Most popular are laser-cut perforations, which start at Ø4mm and can be cut at any size above this. So Prihoda can make a range of diameters, many rows or few, can change the distance between the rows to allow for more entrainment of ambient room air (or less), and can change the position of the rows on the circumference of the duct. An infinite range of variability allows the company to search for and create the optimum air pattern for every application.

Fabric nozzles are available for medium air throw distances. These throw the air in a targeted direction over a longer distance, allowing for wider temperature differences or higher mounting heights. These are available in Ø20, Ø30 and Ø40mm in any number of angles and configurations on the duct.

For very long throw applications, high bay warehousing or sports halls and large swimming pools, large diameter fabric nozzles start at Ø80mm and increase to any required diameter. This delivers a high air volume targeted air pattern with high entrainment.
