Currently, development and improvement of ventilation and air conditioning systems efficiency is related with the use of new devices for air transportation and distribution. These include micro perforated air distributors made of textile which are installed both at the level of the indoor working area and directly near the workplace. Air terminals of this type are made of polymer composite material – fabric based on synthetic fibers. To make such a fabric, modern laser technology to produce micro-holes is used which allows burning in the fabric holes of a given diameter and pitch with melted edges. Results of studies on shape and size of micro-holes in the micro perforated textile terminal are described in this paper. A conclusion is made that the micro–holes shape is irregular and the holes boundaries have uneven edges. Data on micro-holes area range are given. Actual diameter of the micro-holes declared by manufacturer is defined more exactly.
