Duplex filters eliminate process disruption and facilitate continuous and uninterrupted flow. Duplex filters operate in duty/standby arrangement and switch over is achieved with 3 way valves on smaller systems and inlet/outlet butterfly valves or ball valves on larger systems. Our standard and hygienic duplex filters are available for industrial and food & beverage applications. These can be mounted on a skid or trolley for a mobile solution. We can combine any two filter housings from our standard range to offer a duplex filter housing solution. Flow rates range from 1m3/hr to 100 m3/hr. All units are supplied fully assembled with pipework and valves. We can add differential pressure measurement, pumps, and external alarm signals if required.
