Baltimore Aircoil Co., Baltimore, Md., has launched a Whisper Quiet Fan option for the Series 3000 cooling tower. The fan is CTI certified and reduces sound levels up to 19 dBA.

The axial fan blades are constructed of high-grade marine alloy aluminum for rugged construction and corrosion resistance.

The fans require minimal maintenance, making them a good choice for use in cooling tower applications that benefit from extremely low sound operation.
