ABSTRACT:
A filter appliance including a dilution device, wherein the diluted portion remains largely constant when the entire volume flow is modified. Said filter device is characterized in that the flow characteristic—defined by the pressure loss function ΔpB({dot over (V)}B)—of the constituents of the dilution line B is adapted to the flow characteristic defined by the pressure loss function ΔpA({dot over (V)}A)—of the constituents of the filter line A, in such a way that the dilution condition holds good for at least one diluted portion X where X={dot over (V)}B/{dot over (V)}A+{dot over (V)}Bfor volume flows between be {dot over (V)}1=10 liters per hour and {dot over (V)}2=120 liters per hour, first volume flow range, for at least one second volume flow range of at least 5 liters per hour inside the first volume flow range, ΔpA({dot over (V)}A) designating the pressure drop over the dilution line B according to the respective volume flows {dot over (V)}A, {dot over (V)}Bin liters/min of the water in lines A and B.
