Performance & Testing Videos
Smoke tests & diffuser demos
A collection of videos showing how air moves through different types of fabric ducting and diffuser options.
Our patented Directional Microperforation provides highly efficient, draft-free air distribution for low throw distance applications.
Directional Microperforation Smoke Test
Our patented Directional Microperforation provides even, efficient, draft-free air distribution for short throw distance applications.
Uniform Microperforation Smoke Test
Our patented Directional Microperforations uniformly distributed along a diffuser provide completely even, draft-free air distribution in short throw distance applications.
Directional Microperforation vs Permeable Fabric
Short throw distance applications with old design fabric systems rely on permeability of the fabric for air distribution.
Induction of Air From Permeable Fabric
Our Premium and Classic permeable fabrics are typically used in any application where cooling will be below dew point.
Fabric Nozzle vs Plastic Nozzle – Fire Resistance
Old design fabric duct systems use plastic nozzles for long throw distance applications.
Small Textile Nozzle Smoke Test
Our small textile nozzles are used for long throw distance (up to 45 feet) applications. They are made from the same UL/ULC listed fabric as the diffuser body to maintain perfect color matching and full system fire resistance.
The opposite flow dynamics of cold and hot air make comfortable air distribution from a single fabric diffuser difficult, if not impossible.
SquAireTex Swirl Diffuser
Our SquAireTex line of lay-in diffusers extends the benefits of fabric–lightweight, precision air distribution, ease of maintenance–to lay-in ceiling applications.
Diffuser Vibration Scale
Poor diffuser design can cause fabric vibration that is annoying to occupants and detrimental to the diffuser itself.
Prihoda’s Diffuser Winch system for fast, convenient removal and re-installation of diffusers from the inlet of the system.
Textile Air Control Pockets
Our patented Textile Air Control Pockets correct natural deflection of air through perforations to eliminate dead spots and ensure complete space ventilation.
