Ac fans feature smart thermal controls

摘要

A 6-in. energy-efficient ac-fan with smart thermal controls is an addition to the OA172 series of axial fans. It features a ball-bearing design that delivers airflows of 105 to 200 cfm with reduced noise levels of 37.5 to 50.8 dB. The fans provide thermal control to reduce power consumption by increasing or decreasing fan speed ac- cording to the ambient air temperature.
