On designing the EFB, the main focus was finding the optimal performance mix between high airflow and low energy consumption. As a proof of the excellent results obtained, each fan carries a BESS LAB test report. This series is characterized by a strong orifice with an externally square shape, perfectly suited for suspended type installations.
Four suspension hooks are provided when ordered the sk2 kit.
