Air Socks

High-quality materials

Tailor-made solutions

Air Socks can be of various shapes, dimensions, lengths, airflow distribution methods or suspension types. We make our products from various fabric types of different colors. We offer solutions for every situation that always correspond to demanding customer requirements.

Cross section

Positive pressure only

C – CIRCULAR

The standard shape, easy maintenance, preferentially recommended.

H – HALF-ROUND

For use where there is not enough space for circular diffuser and aesthetic applications.

Q – QUARTER-ROUND

For use where there is not enough space for circular diffuser, in aesthetic applications and if the diffuser is to be installed in the corner of a room.

SG - SEGMENT

For use where there is not enough height for
a half-round diffuser.

SC - SECTOR

Available if the room corner construction requires a different shape to quarter round.

OVER PRESSURE AND NEGATIVE PRESSURE

S – SQUARE

This shape requires a special suspension structure (provided) to clamp and support all corners.

Sizes and Diameters

We manufacture fabric ducting and diffusers of all dimensions from 100 mm to 2000 mm, each designed to specific requirements. The duct inlets and connection spigots are always manufactured 10-15 mm larger than the specified size/diameter for ease of connection.

Length

Determining the length of Fabric Ducting & Diffusers depends primarily on the availability of space. We can manufacture a fabric diffuser to deliver the same air volume whether the duct is short or long, the precise design depends on the material type, perforation designs and system pressure.

A – beginning (edge /zip) – length  100mm – 200 mm
B – continuous part (zip/zip) – length 5000mm –10000 mm, these are multiplied to create the correct duct length
C – blind part (zip/end) – length from 100mm to 11000 mm

Individual parts are connecting with zippers; the number of zippers (or the distance between them) is flexible and can be specified by the customer.

Pressure

Pressure losses of Fabric Ducting & Diffusers are very similar to those in the traditional ducting. Calculating a more complex fabric distribution system is achieved using similar methods to those for sheet metal ducting. The minimum static pressure necessary to keep the correct shape of a Fabric Duct or Diffuser depends upon the weight of the fabric used. A minimum of 20 Pa is sufficient for light materials and 50 Pa necessary for medium and heavy ones.

The pressure distribution along Fabric Diffusers is different from traditional sheet metal ducting because with declining airflow longitudinal velocity decreases. To verify the design of your fabric distribution system, please contact us.
