Simple fan

The ECA 100 ipro K is a simple fan with flaps without start delay and overrun time. The fan has 2 speeds for which one needs but a special switch. But also works with a simple switch then stop only at a speed. Fan is easy to install and runs very quietly. Appearance is Geschmakssache. Some rooms (bathroom, WC ..) one should consider whether it would not drauflegt the few euros and you choose the model with start delay and overrun time. Important to me was only the flap, as in winter otherwise all the heat lost by the withdrawal.
