The Parker EADPF iprotect filter improves safety and efficiency by making remote operation possible. When one filter element becomes contaminated, the in-built filter condition indicator sends a signal to the duplex valve unit, telling it to switch to the other filter with a clean element. This enables effective filtration to continue without the need for manual intervention. A warning signal is provided to the local overall system controller, informing the operator that the contaminated filter element requires replacement.

To avoid excessive pressure peaks when putting the new, unused filter element in operation, an equalizing line is automatically activated before the duplex valve is switched over.
