Pressure Gauge for Astral Cantabric Filter Tank

The pressure gauge for the Astral Cantabric filter tank is a diagnostic element that informs the operator of the current working pressure inside the filter tank. An increase in pressure of 0.3–0.5 bar compared to a freshly washed filter signals the need to backwash the sand.

The original part fits exactly into the pressure gauge connection of the Cantabric tank without the need for reductions or additional sealing. The scale covers the typical operating pressure range of pool filtration of 0–4 bar.

A damaged or non-functional pressure gauge should be replaced immediately, because without correct pressure indication it is not possible to reliably control the backwashing, and there is a risk of overloading the filter tank or damaging the pump.
