PPR Female filter 45° f/f

The PPR female filter 45° is a Y-strainer for PP-R pipework that holds back sand, scale and other coarse dirt on a stainless steel mesh before it reaches valves, meters, pumps and appliances. It joins Ø20 and Ø25 PP-R pipe by socket fusion and is rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C.

The PPR female filter 45° is an in-line strainer for PP-R hot and cold water installations. Water passes through a stainless steel mesh screen inside the body, which holds back coarse dirt such as sand, rust particles and scale. The retained dirt settles in the 45° leg, from where it is removed by opening the blind plug during routine maintenance, without cutting the pipe. The body is made of PP-R, from prime-grade polypropylene random copolymer (type 3), to EN ISO 15874-3, nominal pressure PN25. The operating temperature is 70 °C, with a maximum of 95 °C, so the filter can be used on both cold and hot water lines. The brass insert is CW617N with a lead content below 2.2 %, and threads follow the BSP parallel (gas) thread standard. The filter has female sockets at both ends and is joined to Ø20 or Ø25 PP-R pipe by socket fusion, with the same welding tool and procedure as the other fittings in the line. It welds reliably to THERMALINO PP-R pipe and becomes part of a homogeneous, leak-tight pipeline. Welding times and dimensions for each size are in the technical data sheet. The usual position is upstream of the equipment it protects: water meters, pressure reducing valves, pumps, boilers and water heaters. Isolation valves on both sides let the screen be cleaned without draining the system. The filter is supplied in white, in the Smart line series.
