Installation and connections
The module is placed always under a raised floor in a horizontal position. The air, supplied by the air conditioner (Fig. 1 and 4) after being treated, is conveyed under floor and, by the FAM, to the Users (Racks)
Description of FAM 3000 PV
The module is made by a structure of sheet steel, oven painted that includes: a) Axial fan, directly coupled to a variable speed motor (0-10 VDC) to obtain heads and flow rates suitable for the application in place. It is equipped with internal thermal protection, with automatic reset, that intervenes in case of malfunctions of ventilator. b) Air supply through grilles placed above the safety net fixed to the FAN. c) Air intake, through perforated protective plate located under the FAN.
