Barberi® impurity collecting filters are components with cylindrical cartridge, which can be easily extracted and inspected for normal cleaning and maintenance operations. They are normally used in domestic water installations, booster pump systems, heating systems, central heating systems, heat generators (wall-mounted boilers, solid fuel generators, heat pumps), thermal solar systems, generic industrial and agricultural water systems. In case of applications with high temperatures, the P21V series filter can be considered. P22 series filter and P23 fitting are normally used for the installation of drain taps or probe-holder pockets.
Acceptable working temperature range (peaks):
-20 (see suitable fluids)110 °C (P21, P22, P23)
-20 (see suitable fluids)175 °C (P21V, P23V)
Working temperature range:
0 (no frost)95 °C (P21, P22, P23)
0 (no frost)150 °C (P21V, P23V)
Max working pressure: 16 bar
Suitable fluids: water for thermal systems, glycol solutions (max 30%, max 50% P21V, P23V), domestic water
Threaded connections: ISO 228-1
