FAQ:

Q: What direction does the fan rotate?
A: Clockwise when viewed from the motor side.

Q: Can it run on 12V?
A: No. It’s designed for 24V systems (16–32V range).

Q: What is its guaranteed lifespan?
A: At least 25,000 hours; can reach up to ~40,000 hours in optimal conditions.

Q: Can I control the speed?
A: Yes, it supports PWM for variable speed control.

Q: Is it suitable for wet / dusty use?
A: Yes, rated IP68. Still avoid direct high-pressure jets or immersion.

Q: How to confirm compatibility with my system?
A: Check physical dimensions, mounting pattern, airflow / pressure demands, and electrical specs before purchase.
