Installing evaporative air cooler air duct need to take attention to the high quality air cooler. It can ensure evaporative air cooler air duct ventilation cooling effect! Evaporative air cooler air duct installation is not flat, center offset, uneven flanged interface , which will impact effort. Two buildings air duct system is too large, resulting in ventilation cooling not well effect!
Hearing the outlet roar is the best way to check no leakage ! We need to reserved holes and embedded boom when installing evaporative air cooler air duct avoid the elevation and the coordinate position offset horn.
After duct installation, do not let the large wind horizontal and vertical deviation. As well as in the installation of evaporative air cooler air duct need to be careful. The surrounding air cooler embedded steel casing and duct gap is not equal to the outer casing. Partial section needs to be consistent! The gap between the duct and the flange as small as possible when the air cooler running.
