Making a hot job bearable changes the whole mindset and increases the care with which a worker does their job. Adding a dock or truck cooler fan to your loading/unloading areas is the key to worker attitudes of enthusiasm or indifference. This 16 x 16" fan powered by a Select Voltage, 3/4 HP motor moves 2800 cubic feet of air per minute with an air throw distance of 60' feet - plenty of air movement to keep heads cooler and clearer.
