Equipped with a fan rotation detection feature! It can issue an alarm in case of a malfunction that causes a decrease or stop in rotation!

The "Variable Airflow Fan Unit" is a device designed to efficiently introduce cold air from under the floor into server rooms that utilize a free access floor. By installing it at the front of the server rack, it forcibly draws cold air from below and sends it to the intake side of the servers, achieving high cooling effectiveness. Using multiple fans allows for a high airflow supply. The poor flow and stagnation of cold air caused by underfloor cables and racks are also forcibly directed into the room by the high airflow fans. 【Features】 ■ Variable airflow ■ High airflow ■ Compatible with standard-sized free access floors ■ Rotation detection alarm circuit (contact alarm) ■ Durable fans (expected lifespan: approximately 40,000 hours at maximum airflow) *For more details, please refer to the PDF document or feel free to contact us.
