Flexible ducts for ventilation and air conditioning
Using unique technology and accessory with modern equipment allows producing semi-flexible air ducts with ultra strong triple lock made from aluminum (ALUVENT ??), stainless and galvanized steel strip (Thermovent ??) with thickness 50 to 120 micron. Besides them we produce elastic (frame-film) non-isolated (POLYVENT ??) and isolated (ISOVENT ??) air ducts. Both types of air ducts are widely used in the ventilation, heating and conditioning systems.
choose, corresponding to diameter in mm(event 200mm)
find cross point to this lines with vertical line of the required volume of the air in m3/ch (in event 500 m3/ch) Through cross point these two films passes horizontal line, showing value of the loss of the pressure in pascal (Step) on one metre
The Multiplying values of the loss of the pressure (in event 2,4 Steps/m at the temperature of the air 200?) get fat length given area, get the general value of the loss of the pressure. For calculation of the loss of the pressure at presence, each equales to one metre.
