Industrial duplex filter with remote and automatic switchingParker Hannifin is introducing an innovative duplex filter system for use in a wide range of industrial applications. Designed to improve both safety and filtration performance considerably, the EADPF iprotect filter incorporates Parker’s hydraulic solenoid valve technology, making it possible to switch between filters remotely and, therefore, optimise productivity.

While conventional duplex filters require the main duplex valve and equalising line to be operated manually, the new Parker EADPF iprotect filter improves safety and efficiency by making remote operation possible. Furthermore, this process can be fully automated, thereby cutting maintenance requirements and machine downtime.

When one filter element becomes contaminated, the built-in filter condition indicator sends a signal to the duplex valve unit, instructing it to switch to the other filter with a clean element. This enables effective filtration to continue without the need for manual intervention. At the same time, a warning signal is provided to the local overall system controller, informing the operator that the contaminated filter element requires replacement. Routine maintenance can then be carried out at a convenient time.

To avoid excessive pressure peaks when putting the new, unused filter element in operation, an equalising line is automatically activated before the duplex valve is switched over. This eliminates the risk of human error associated with carrying out this process manually, ensuring safety and avoiding damage to system components and seals.

Parker's EADPF iprotect filter is fully compatible with the company's patented filter elements for proven effective filtration, and is backed by Parker's global supply and support network.
