The W1G250-BB21-01 from EBM-Papst is an EC axial fan with a wall ring, designed for efficient and energy-smart ventilation. The fan comes complete with an ESM housing made of PP plastic and an integrated protective grille, ready for installation in demanding environments. Thanks to the built-in EC motor M1G055-BI, it offers two speed modes and soft start for smooth operation.
The fan is ideal for ventilation and cooling applications in industry, cooling units, and air handling systems. Its selectable mounting position and robust IP55 housing make it equally suitable for indoor use and tougher outdoor environments.
