    Features of MP Filtri LDD filters:

    • Integrated changeover function to allow the filter element to be replaced without system shut-down
    • Female threaded connections up to 1 1/2” and flanged connections up to 1 1/2”, for a maximum flow rate of 330 litres/minute
    • Balancing valve integrated in the changeover lever, to equalise the housing pressure before the switch
    • Vent ports, to avoid air trapped into the filter going into the system
    • Drain ports, to remove the uid from the housing prior the maintenance work
