The SYR house filter is a simple and cost-effective accessory for every family house or apartment unit. It reliably captures tiny particles of rust, metal chips, sand or sediments that reach home with drinking water. The house filter provides protection against pipe corrosion, damage to fittings, clogging of aerators, etc. The SYR DFR house filter includes an integrated pressure limiter , which protects against damage to the system by high pressure. The filter is cleaned by means of a "backwash". This eliminates the need to replace the filter element and the associated service and spare parts costs.
