Ducter 2.5 is used for the selection of air duct cross–section. This program will help you to calculate the air consumption in cubic meters or liters, as well as limit the speed of air in air duct. It is possible to set the level difference for natural exhaust.

Ducter 2.5 program is suitable for engineering workers, as the selection of air duct cross-section is carried out in-line. This program allows to carry out the calculation of pressure drop and air temperature in the air-duct. When entering the parameters, the program calculates the pressure on the air-duct section. There are air-ducts made of different materials in this program.
