What IP rating do I need for outdoor fan installation?

Outdoor fan installations require minimum IP54 (dust-protected + splash-proof). For exposed locations: IP55 (dust-protected + water jet resistant). For washdown/food processing: IP65 (dust-tight + water jet resistant). For submerged or high-pressure wash: IP67 or IP68. Common scenarios: - EV charger (sheltered): IP54 - Telecom cabinet (exposed): IP55 - Food processing (washdown): IP65 - Marine/offshore: IP66 or higher with salt-spray corrosion protection.
