Prihoda’s textile air dispersion options, combined with a wide range of available shapes, make it possible to engineer precisely designed air dispersion systems for virtually any space.

Perforated Fabric Duct System

Large fabric nozzles

Our large fabric nozzles are constructed with an integral manual damper for precision balancing, which ensures even ventilation in large spaces with high-volume demand and long-throw distances, such as manufacturing facilities and warehouses. Large nozzles are available in a fixed-direction or adjustable version, to allow precise user control.

Prihoda’s unique, patented process for laser cut microperforations provides the most efficient and most effective air dispersion for shorter throw distances. Diffusers with microperforations ensure comfortable, draft-free ventilation for offices, classrooms and other lower-ceiling installations.

Prihoda Perforated Fabric Duct System

Small fabric nozzles

Our small fabric nozzles are ultrasonically welded to the duct and are ideal for applications with medium to long throw distances. All fabric nozzles are constructed of the same UL-listed fabric as the diffusers themselves, guaranteeing a perfect color match and full-system fire resistance.

Precision laser-cut perforations are located wherever necessary along a diffuser to provide optimum air distribution in higher-ceiling installations, such as gymnasiums natatoriums andindoor agriculture facilities.

Common Questions about Fabric Duct Systems

What industries do you serve?

We serve a wide range of industries including, but not limited to, commercial, residential, industrial, health and wellness, educational, and sports facilities.

How does a fabric duct system work?

The fabric duct system operates by dispersing air through a specially engineered duct made of fabric. It works much like traditional metal ducts, but it allows for a more uniform and efficient air distribution without the risk of condensation due to the use of permeable materials.

What are the advantages of fabric ducts over metal ducts?

Fabric ducts offer several advantages over traditional metal ducts. They are lighter, more cost-effective, easy to install, will not sweat, rust, or corrode and provide superior air distribution. Additionally, they can be laundered for hygiene maintenance, which is particularly beneficial for environments like food processing plants or hospitals.

How to clean fabric ducts?

Our fabric ducts are designed to be easy to clean. Most can be washed in a standard washing machine, but please check the specific cleaning instructions for your model.

Are fabric ducting systems customizable?

Yes, fabric ducting systems can be tailored to fit the specific requirements of any environment. This includes various shapes, sizes, colors, graphics, patterns and air dispersion options to cater to unique architectural or aesthetic needs.
