NBF Fan

American Coolair’s Type NBF fan provides the solution to fresh air ventilation in most types of farm buildings. 

Type NBF fans are built to give you years of heavy-duty trouble-free service. 

The rugged, belt-driven construction operates in any position, has permanently lubricated ball bearings, and is available with single- or tw o-speed totally enclosed motors. 

Coolair has developed a complete ventilation system for farm use combining the Type NBF fan with a Type LRW all aluminum shutter and heavy gauge galvanized steel wall housing (square box or slope) for exterior mounting, allowing a maximum of unobstructed interior space. 

EXCLUSIVE DRIVE ASSEMBLY. Our engineers have developed an innovative drive assembly for the Type NBF fan. 

Power is applied through V-belts directly to the propeller with blade load concentrated directly over the bearings to eliminate overhung bearing load. 

The exclusive, time tested design has been widely acclaimed by engineers. Our use of quality materials and precise engineering techniques in constructing wheel assemblies assure you of years of quiet, trouble-free service.BASIC
