FANJET — Fan Filter Unit (FFU)
A self-contained HEPA/ULPA fan filter unit. Air is drawn through a G3 pre-filter by a powerful, quiet motor-fan and filtered by a HEPA (ULPA option) absolute filter; the MONOBLOC construction guarantees box integrity. ECM versions allow automatic flow regulation and centralized PC control (Modbus / BACnet). Available as the MONOBLOC version, whose welded construction guarantees full box integrity, and as the FANJET SP, whose absolute filter is interchangeable directly from the clean room — without dismantling the unit.
