HS74CA-3/4AD

Honeywell Fully automatic combination water supply unit with automatic reverse rinsing actuator, HS74CA

HS74CA combination water supply units integrate pressure reducing valve, reverse rinsing fine filter, non-return valve, and automatic reverse rinsing actuator in one appliance. Therefore, these units comprise all armatures needed for private water supply systems and ensure continuous supply of filtered water. The pressure reducing valve prevents overpressure damage and reduces water consumption. The fine filter stops the ingress of foreign bodies. The non-return valve protects the mains water system. The automatic reverse rinsing actuator operates with batteries, therefore, there is no need for a bus bar in the area of the water supply. It is responsible for the fully automatic cleaning of the fine filter. All individual units correspond to the requirements of current DIN/DVGW specifications.
Approvals: DIN/DVGW for filter combination FK74C and for non-return valve RV277
