This is the VEVOR 8″ EC inline fan with built-in digital speed controller and display. This specific EC + digital controller version is currently no longer available from VEVOR in the UK EC motor design provides higher efficiency, quieter operation and more stable speed control compared to AC alternatives. I purchased multiple units for a project. I kept a few as spares but happy to let this one go as surplus. The item is sealed in original box. UK stock – immediate dispatch.
