Do you offer installation and/or cleaning services?
Yes in certain circumstances we will be able to offer a Prihoda Approved installation. This ensures that the duct is installed to all of the best installation practices and recommendations. Our installation teams have all of the necessary site qualifications and certifications and are also certified and qualified to operate a wide range of plant […]
What shape does the Fabric Duct take when the air is turned off?
Please click on the picture above. The Fabric Duct system can be designed to take on a variety of shapes to suit the circumstances, by either using additional support rails or by adding rings that maintain shape when the duct is deflated.
This is difficult to answer as it depends on the environment in which they are installed and how well they have been installed and are looked after. Most of the materials we supply in the UK have a 10 year warranty so we would expect 10 years life as a minimum. The material is rugged […]
Click on the picture to view There are 9 stock colours with our standard and premium products all of which are available at no additional charge. Our Recycled Fabric Duct is available in 4 colours as standard (White, Light Grey, Dark Grey and Blue). Non standard colours and printing on the ducts are also available […]
It’s pretty much the same as rigid duct. We don’t like to go higher than 8.0m/s if possible, but generally we’ll design at velocities much lower than that for most non industrial applications and of course 2.0m/s or less for really quiet areas. We provide noise data calculations for most selections so it’s easy to relate velocity/diameter/noise within […]
In a well designed straight diffuser there is almost constant static pressure throughout. The laser cut perforations are calculated (size/quantity to create the diffusion area) to match the available static pressure. In other words the Fabric Ducting system is designed based upon the available static pressure of the system. Bends and other shaped pieces create […]
Do you have an Extract Fabric Duct (Negative Pressure Duct)?
Yes we do. This is usually rectangular and held in shape with a rigid suspension system…. please see further details on the Innovations page and also contact us for further information and a selection.
What about commissioning / balancing the system(s)?
Typically a Fabric Ducting system is designed to match the volume and pressure of the AHU system. It’s designed to deliver a certain volume of air for each branch which has been designed and calculated as part of the overall system design. Assuming no branches to other systems or non fabric diffusers exist within the […]
As every duct is made to order average delivery time is about 3 weeks from date of agreed design following order – plus a day or two shipping. During winter months when there is less production pressure this may reduce to two weeks delivery time. Conversely during summer we may be quoting 4 weeks delivery […]
