Replacement Parts

Looking for replacement OEM parts for your control system?

Replacement main logic modules (MLMs) and user interface modules (UIMs) for ALL V-Series controllers (Vantage, Maestro Legend, ProTech) are no longer available.

Bay Controls is excited to announce the release of the Series 7 controller. While the Series 7 is a huge leap forward in air compressor control, it only takes a few simple steps to upgrade from a legacy Bay Controls Controller (ProTech, Vantage, Maestro Legend, etc.).  Retrofit kits for all old OEM controls are also available.

​Below are some common Cameron part numbers and their corresponding Bay Controls part:

  • ​AAP3798102-00031: Bay Controls MLM

  • AAP3798102-00037: Bay Controls UIM

  • AAP3798102-00036: Bay Controls UIM Backlight
