Sporlan offers an exclusive concept in Suction Filter design - a filter with an optional relief feature.
When flow is in one direction, the bypass relief feature is active.
If the pressure drops across the element becomes excessive the bypass relief will open slightly to maintain sufficient gas flow and assure proper cooling of the hermetic motor.
When the Suction Filter is installed the flow in the opposite direction, the bypass relief feature is inactive and will never open regardless of the increase in pressure drop.
The "T" in the part number indicates these models are equipped with an access valve to permit pressure drop readings. The access valve will be operational provided the Suction Filters are installed with the bypass feature inactive.
