What is the full redundancy for ventilation for the enclosure for ESD protected machinery spaces ?
Direct Answer
Option A: 2x100% capacity fans from different electrical circuits
IGF Code Section 15.8 requires that ventilation systems for ESD-protected machinery spaces maintain a negative pressure and provide full redundancy. This necessitates two 100% capacity fans powered by independent electrical circuits to ensure continuous gas dilution and safety, even in the event of a single power or fan failure.
