The Resideo F78TS flanged reverse rinsing filters are designed for installations that require a high demand for water. These filters are ideal for large residential buildings, central water supply systems, and various commercial or industrial applications. The F78TS models feature the same advanced reverse rinsing filtration system found in our range of household fine filters. Additionally, they can be retrofitted with the Z11AS fully automatic reverse rinsing actuator and the DDS76 differential pressure switch. This fine filter effectively prevents the ingress of foreign materials, such as rust particles, strands of hemp, and grains of sand, thereby minimising the risk of corrosion.
