Prihoda is known worldwide for innovative products and patented developments in fabric ducting technology. But we’re most admired for our technical expertise in helping professionals design custom-engineered systems. Our robust AirTailor® software, unique to Prihoda, is the key to precision design.


Providing training in the design and applicability of air ducting and dispersion systems has been a priority with Prihoda for years. We have presented textile air dispersion courses in Denver, Atlanta, Chicago, and other cities all over the country, and a self-paced online version is now available.


Our 32-page Technical Data Catalog has details on all our air ducting products and diffusers, including specialty products, solutions for medium to high throw applications, and solutions for problematic air flow, plus information on materials, maintenance, and frequently asked questions.


Prihoda is here to support you during the design and selection process and can provide written specifications, Autocad Mounting Details, and many other items from our downloads section. If you would like a detailed selection or design, please provide us with as much information as possible here.
