New Fabric Ducting Makes Ventilation a Breeze

Prihoda is a Czech company who truly understand air temperature and air movement. They have developed textiles that are cleanroom quality, strong, flame-resistant, and have a 10-year warranty. Every air distribution system is designed from scratch specifically for each site and application. Recycled fabric options are also available and are manufactured from used plastic bottles, with reduced consumption of energy by 66%, water by nearly 50% and greenhouse gas emissions by over 34%. Fabric air ducting and diffusion can cater to a diverse range of industries such as indoor pools, schools, laboratories, food, sports, light structures, offices, restaurants, cinemas, retailers and many more.

Fabric ducting has considerable advantages over other types of HVAC ductwork. It provides more controlled air velocity and a comfortable environment with lower noise levels than rigid ducting. Greater safety is offered by the higher fire resistance of the material over plastic ducting. No seismic restraints, other than the cable system that supports the very light weight of the duct, are required to meet NZ standard (NZS4219:2009) for earthquake safety. Maintenance is also arguably much easier with fabric ducts as they can be removed (unzipped), machine washed and re-installed. Fabric ducting systems cost less than rigid ducting and the associated grilles, especially if that system has to be insulated. It also takes less time to install.

Perhaps the greatest feature of fabric ducting for those who are creatively minded is a customisable look that has the ability be fashioned using any colour or with printed graphics that make this product a uniquely artistic ventilation option.

Earthquake safety:

No seismic restraining is required to meet the NZ standard NZS4219:2009. Fabric ducting is not covered in the code as it is very light weight. No further restraints other than the cable systems that support the duct are required.

High Rigidity and Strength. Prihoda basic Classic, Premium and Recycled (PMS/PMSre/NMS/NMSre/PMI//NMI) fabrics demonstrate optimum rigidity of 1800 N/10mm in the texture and 1000 N/10mm in the weave. These parameters make tearing of the material in normal use almost impossible.
High Fire Resistance. The PMI/NMI/PMS/NMS fabrics are certified to European standard EN 13501-1 with excellent results. Fabrics achieve B-s1,d0 classification, which means prevention of spread of fire, minimum smoke production and no burning drops. Glass (NHE) fabrics in fact meet class A requirements. Classic, Premium and Recycled (PMI/NMI/PMS/PMSre) fabrics are also certified to US norm UL 723.
Negligible Fibre Shedding. Due to the use of endless fibres, all Prihoda fabrics can be used in cleanrooms up to ISO Class 4. Independent laboratory tests demonstrate that there is practically no particle shedding from the material during operation.
Antistatic Effect. Woven carbon fibre in Premium (PMI/NMI) and Durable (NMR) materials removes any build up of electric charge from the surface of the fabric.
Antibacterial Effect. Utilises a special treatment which guarantees that no bacteria can survive if settled on to the fabric Premium (PMI/NMI) and Durable (NMR). This treatment remains effective after multiple washing. Tests for the European standards found that after ten washes there was no reduction in the efficacy of the treatment. This allows Prihoda to offer a 10 year warranty on the basis of the minimal maintenance requirements.
Easy to maintain. The fabrics, which are manufactured using endless fibres, are very effective and minimise settlement of impurities from the supply air. This supply air is distributed through the diffuser perforations, and the Fabric Ducts remain relatively clean inside (in a normal environment). They do not require any other maintenance than outer dusting. Washing is normally only required for either hygiene or aesthetic reasons.
Stable Appearance. Thanks to Prihoda's endless fibre technology, the appearance of the fabric does not change over time, or with multiple washing cycles, unlike materials made of basic fibres. The Premium, Classic a Recycled (PMI/NMI/PMS/NMS/PMSre/NMSre) materials remain aesthetic after many maintenance cycles

10 year warranty is given on medium weight polyester fabrics such as Prihoda Regular, Prihoda Premium and Recycled Material. This is 99% of the material specified in most cases.

Fabric is typically unzipped and cleaned in a washing machine then reinstalled
