The Big Dog Fans

The BIGDOG Fan from Big Fogg provides massive air-movement to provide the most industrial cooling for plants, factories and facilities. Unlike high volume & low speed industrial fans that can move a lot of air BUT ‘very slowly’. These slow paced industrial fans like Big Ass Fans just don’t provide enough industrial cooling. , Schaefer’s 72″ The BIGDOG Industrial Fan & ventilator from Big Fogg moves massive amounts of air with over 45,000 cfm of power.

The 72″ BIGDOG Fan ventilator is a 72″ diameter, 3 Hp, belt-drive, fiberglass, 6-wing (aluminum), variable speed circulation industrial fan fitted with 6 fully adjustable fiberglass air deflectors, allowing the air stream to be aimed wherever it is needed.

The optional variable frequency drive allows a smooth speed adjustment from 300 RPM to 50 RPM. Power consumption ranges from 2,200 watts to 300 watts depending on the industrial cooling needs.

The BIGDOG fan from Big Fogg can be hung from the ceiling or post/wall mounted using optional post/wall mount hardware. The BIGDOG fan from Big Fogg should be mounted at least 14 feet high, for optimal air distribution, and at least four feet from the ceiling to avoid choking the fan’s air supply. The BIGDOG from Big Fogg can be mounted horizontally, with the deflectors spreading the heat both left and right, or can be mounted on an angle with the deflectors pointing in the same direction the industrial fan is already pointing.

At full power, the air speed at the industrial fan outlet is approximately 1,500 FPM (feet per minute) with total airflow of approximately 45,000 cfm (cubic feet per minute) and with an efficiency of greater than 20 cfm/watt. High efficiency results from the shape of the industrial fan’s venturi (cone) and the air straightening effect of the galvanized motor mounts. Air speed at ground level is dependent on the orientation of the deflectors, but can easily be in excess of a refreshing 100 FPM over an area 200′ long by 35′ wide, or 7,000 square feet.

At full speed, the BIGDOG fan from Big Fogg is a large area personnel or equipment cooler. At lower speed, the BIGDOG fan from Big Fogg is an air de-stratifier, redistributing tapped hot air from the ceiling and dramatically reducing heating bills. The BIGDOG fan from Big Fogg is easy to install and is extremely quiet and efficient at all speeds.
