Materials
Custom-made airsocks are in various circumstances the most durable and cost-efficient application to ensure healthy indoor air. Prihoda has a wide range of materials available to realise exactly the air distribution system that meets 100% of the client's requirements and/or legal guidelines. In the chart below you will find a complete overview of the materials, permeable or non-permeable, that can fit your project with air socks.
Bye bye condensation, bye bye draught !

CLASSIC (PMS, NMS) OR PREMIUM (PMI, NMI)
Fabric Premium is unlike Classic in addition antibacterial and antistatic. Through these properties they are predetermined to use in the environment with the highest hygienic requirements or where it is necessary to prevent arising electric voltage between textile diffuser and earthing. Although the both categories reach usually the rank for the same class according to the flammability, fabric Premium are besides equipped with the special modification for minimization of combustion and fumes.
AIR-PERMEABLE (PMS, PMI, PLS) OR NON AIR-PERMEABLE (NMS, NMI, NLS, NMR)
The only reason for usage of the air-permeable materials is need to prevent the water condensation on the surface of the diffusers. When in cooling with the temperatures under the dew point the non air-permeable material will behave like steel ducting and it is necessary to use air-permeable fabric, alternatively double or insulated ducting.
LIGHT MATERIALS (PLS, NLS)
Their lower price is balanced with shorter warranty and life-time. Compared to other fabrics, these light materials are easy to wear out by washing and they will not last more than 50 washing cycles. Thanks to extreme low weight they are pleasant to touch in manipulation.
FOILS AND COATED FABRIC – FOIL (NLF), PLASTIC (NMF), GLASS (NHE), TRANSLUCENT (NMT)
They can´t be washed in the washing machine, but on the other hand it is possible to clean them with the water flow and with wiping. Foils are the most convenient material with regard to price.
RECYCLED MATERIALS (PMSRE, NMSRE)
They are made of fibers gained through recycling of PET bottles and their usage will contribute to the protection of the environment. Every square meter of this fabric saves 13 PET bottles from the waste dump. Recycled materials aretechnically equal to category Classic.
Prihoda airsocks are available in 9 standard colours.
These are white, yellow, light grey, dark grey, green, red, light blue, blue and black.


Forms
Prihoda produces textile ducts in different shapes according to the customer's specific needs. Standard round channels, semi-circular or quarter-round, segments or sectors or even rectangular channels. All types of channels are custom calculated and made by our team!

Air distribution
Textile ducts are a universal air distribution system that can cover the entire range, at any requested flow. We achieve the required flow profile by choosing the correct discharge method. Different air delivery methods can be combined in one duct.

Airflow
The air flow always depends on the static pressure and the temperature difference, and changes whenever one of these parameters changes.

Installation
Each HVAC project with textile ducts is customised. In addition to a choice from several available textile types, the choice of mounting and/or suspension is also important. This often depends on the available space, the type of ceiling, the existing lighting, to the specific wishes of the client and engineering office. Prihoda offers many options for a smooth and safe installation. Want more information? We will gladly help you.
