The Fomtec ZF-series represents an extension of the existing line of BFZ-inductors, designed especially for use in fixed installations at lower system flow rates. Thanks to the fixed shunt (compared to membrane) it is less sensitive to pressure peaks that can occur in pipe systems. The built in non-return valve prevent water from reaching the foam concentrate storage tank.
The Fomtec ZF inductor can be specially calibrated with following optional settings or accessories:
Each inductor is factory machined to match the specific system requirements. The possible calibration point for the ZF fixed flow inductor is typically between 100 and 600lpm, depending on system parameters. To ensure that the correct performance is achieved, the following parameters must be defined at the order stage:
