From emb-papst, this centrifugal fan is reliable and efficient- ideal for when low maintenance and high performance are a must. The robust housing features a sturdy flange for convenient mounting. ⢠The speed of these centrifugal fans, when equipped with an external rotor, can be adjusted by reducing the supply voltage using a variable speed controller. ⢠The impeller is crimped straight onto the rotor. ⢠For single inlet models, the casing is made of unpainted injected aluminium. ⢠For double inlet models, the casing is made of galvanised steel. ⢠Variable speed controllers are also available. ⢠Thermal protection by thermocontact and windings. ⢠The following centrifugal fans require a motor run capacitor: 4988601 (1uF), 2183208, 2183191 & 4988617 (2uF), 4988409 (6uF) Supply Voltage = 230 V ac Blower Type = Centrifugal AC or DC Operation = AC Air Flow = 260m³/h Series = G2E120 Height = 184mm Width = 178mm Depth = 115mm Dimensions = 184 x 178 x 115mm Fan Speed = 2350rpm
