Filter device test apparatus, filter integrity testing method and computer program product

A valve unit (77)

• fluidly connectable to a filter device (3) having a fluid inlet (7), a fluid outlet (9) and a venting port (11) and
• connectable to an external filter integrity testing device (15) having at least one of a pressure sensor (17) and a flowmeter (63), wherein the valve unit (77) comprises:
• an inlet connector (19) fluidly connectable to the fluid inlet (7),
• wherein the inlet connector (19) is fluidly connected via a wetting liquid supply valve (V4) to a wetting liquid supply, and
• wherein the inlet connector (19) is fluidly connected via a drainage valve (V3) to a first drain (45);
• an outlet connector (21) fluidly connectable to the fluid outlet (9), wherein the outlet connector (21) is fluidly connected via an outlet valve (V2) to the first or a second drain (49);
• a venting port connector (23) fluidly connectable to the venting port (11),
• wherein the venting port connector (23) is fluidly connected via a measurement gas valve (V5) to a complementary measurement gas connector (85), which is fluidly connectable to at least one of the pressure sensor (17) and the flowmeter (63) of the filter integrity testing device (15),
• wherein the venting port connector (23) is fluidly connected via a venting valve (V6) to a venting pipe (53), and
• wherein the venting port connector (23) is fluidly connected or connectable via the measurement gas valve (V5) to a measurement gas source (59);
• wherein the valves (V2, V3, V4, V5, V6) comprise communication means (71a-71g) for communicatively connecting the valves (V2, V3, V4, V5, V6) with the filter integrity testing device (15) allowing the control of the valves (V2, V3, V4, V5, V6) by means of the filter integrity testing device (15).
