Is the Daikin outdoor unit protected against corrosion?

Yes — every model in our catalogue has anti-corrosion protection: DNNS coating, BTA oil treatment, and Blue Fin coating are all present across all 78 real models, not just premium ones. This matters most in coastal or high-humidity areas where salt air and moisture accelerate wear on an outdoor unit.

Since this protection is universal across the current lineup rather than a differentiating feature between models, you don't need to specifically shop for "anti-corrosion" as a filter — every real model already has it. What still varies by location is how much it matters: a coastal installation benefits from this protection far more than an inland one, even though the hardware itself is the same.
