Micro Matic PRO-MAX Replacement Spring – FOB Detector Component

Description

The Micro Matic PRO-MAX Spring is a precision replacement component for the PRO-MAX series Foam-On-Beer (FOB) detectors. This specialized spring provides the necessary tension for the internal float and reset mechanism, ensuring that the beer line is instantly shut down when a keg runs empty. Constructed from high-quality stainless steel, it is resistant to corrosion from beer and cleaning chemicals, ensuring the responsive and reliable performance required in high-volume draught systems.

Technician’s Repair Tip: If your FOB detector is failing to reset or the float is “sluggish” after a keg change, the internal spring may be weakened or fouled with “beer stone.” When performing a chamber rebuild, inspect the spring for any signs of deformation. Clean the internal assembly with a mild acid-based line cleaner before installing the new spring to ensures friction-free movement.
