What are air socks?

Air socks from Prihoda are one of the most innovative air diffusion products on the market. Also known as fabric socks, fabric ducting or textile diffusers, they are a form of diffuser that uses a duct made out of fabric material to deliver air into a space.

A Prihoda air sock diffuser is made from flame retardant polyester material and delivers the air into the room via a variety of methods (micro-perforation diffusers, laser cut perforations or fabric nozzles) depending upon the application. The choice is influenced by how far we want the air to travel and the velocity needed in the occupied zone. As air sock manufacturers, we design and produce your air socks exactly to your application’s requirements.

Which applications are best suited to an air sock system?

Because all our air socks are designed and manufactured on a custom basis, it is fair to say that almost any application is suitable for an air sock system. Fabric ventilation socks suit some applications particularly well, including:

  • Food manufacturing facilities – air sock ventilation can provide low air velocity for large volumes of chilled air, easy maintenance
  • Laboratories – make up air at low velocity for fume cupboards, easily cleanable
  • Large open architecture spaces – more cost-effective than traditional ducting, better air distribution
  • Retail premises – accurate air patterns, cost-effective, great branding and promotional opportunities with Prihoda Art
  • Sports halls – large flexible ducts good at distributing air evenly, even in badminton courts
  • Swimming pools – material unaffected by chlorinated environment (no need to protect), more cost-effective, opportunity to use Prihoda Art for branding and aesthetics
  • Any one off bespoke architectural space – always custom designed with a range of shapes, colours, printing options, suspension solutions, etc.

What are the benefits of using air socks for ventilation?

Air socks for ventilation offer a cost-effective purchase price and a fast installation time. Alongside this, they can achieve superb performance in air delivery, as air socks have a large surface area in the room, allowing delivery of air equally and efficiently all over the space. The air sock material is rugged and long-lasting and comes with a 10-year warranty.

How do fabric air socks work?

An air sock ventilation system inflates using the external static pressure created by the fan from the air handling unit, fan coil unit or evaporator fans. It uses this energy to maintain its shape and deliver the air through the fabric duct and into the occupied zone (or process).

To ensure that the textile ducting delivers the correct velocity, we have software that creates airflow graphics for each unique fabric air sock system, showing how far the air travels and its velocity as an air pattern.
