Schaefer BD72-208460-3 Big Dog Industrial Air Circulation Fans 72 Inch

Schaefer 72 Inch BIGDOG can move a massive amount of air at high speeds.

Typical ceiling fans move lots of air at a low rate of speed which results in minimal cooling. The Schaefer Big Dog provides summer cooling that employees need to work safely and more productively, while DE stratifying (warm air is pushed down from above) in winter to keep employees warm and reduce energy costs.

Misting Control System

Control misting along with your BIGDOG circulation fan by installing the mist control system. Schaefer's MCS will sense ambient humidity & turn off your low pressure mist system as humidity rises to ensure that the floors won't get wet & the air won't get oversaturated.
