The FPSA-T is FlexPak's semi-automatic control package that upgrades manual vacuum leak detectors with industrial PLC control and HMI operation. All pneumatics are integrated into a water-tight stainless steel enclosure, requiring only a single air line connection to the vacuum chamber — no electrical connections needed at the test chamber itself. The system supports both compressed-air venturi vacuum generation (0–27 inHg at ~75 psig / 13 SCFM) and electric vacuum pumps (0–25 inHg), operating from a 120–240V AC, 15 A supply with CSA, UL, and CE compliance.

What test methods does the FPSA-T support?

The controller stores two independent test parameter sets, each with its own vacuum setpoint and countdown timer. Operators can program two successive vacuum levels within a single test — for protocols requiring step-pressure exposure — or switch between two entirely different test profiles with a single button press. Standard supported methods include ASTM D3078 (bubble emission test for flexible packaging), ASTM D5094 (liquid-filled container integrity), and ASTM D4991 (rigid container vacuum testing). This two-program storage eliminates manual valve adjustment and gauge reading between product changeovers in mixed-production environments.

Is the FPSA-T compatible with existing leak detectors?

Because the FPSA-T communicates with the vacuum chamber exclusively through the pneumatic airline, it retrofits to all FlexPak leak detector models and similar competitor vacuum-style bubble-test systems without chamber-side electrical modifications. It is fully compatible with electric vacuum pumps but is not designed for use with FPIPA fully automatic controllers. The single-airline architecture makes installation a matter of connecting the compressed air supply and the vacuum chamber line — no chamber rewiring, no sensor calibration required.
