A: The GR31C-ZID.DG.CR, with its 4200 RPM speed, is specifically designed for applications requiring high static pressure in a compact form factor. It's ideal for pressurizing enclosures, overcoming resistance in dense ductwork, or providing targeted cooling in machinery where space is limited.
A: It means the fan's motor is designed to operate on two common 3-phase industrial voltage standards: 380V (50Hz) and 480V (60Hz). You must connect it to the matching voltage and frequency supply as per your local grid. Always refer to the wiring diagram before installation.
A: This is a standard AC fan motor. For simple on/off operation at full speed, it can be connected directly via a suitable contactor. For variable speed control, an external frequency inverter (VFD) compatible with 3-phase 380-480V motors is required.
A: Yes. The official ZIEHL-ABEGG datasheet containing full performance curves, detailed specifications, and installation drawings is available for download. Please contact our support team at [email protected] to request it.
