Economical, Practical, Effective
NBF fan provides the ideal solution to fresh air ventilation in most types of greenhouse buildings. 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 two-speed totally enclosed motors. Coolair has developed a complete ventilation package by combining the NBF fan with an all aluminum shutter (Type LRW) and a heavy gauge galvanized steel wall housing (square box or slope) for exterior mounting, allowing a maximum of unobstructed interior space.
The fan panel is fabricated of heavy gauge steel and features an all-welded construction. The uprights which support the motor and propeller are formed from heavy gauge steel for maximum strength and rigidity. Painted parts are coated with a thermosetting epoxy coating to provide a protective coating rated excellent for hardness, impact resistance, adhesion and chemical resistance.
Exclusive Drive Assembly
Our engineers have developed an innovative drive assembly for the NBF fan. Our use of quality materials and precise engineering techniques in constructing wheel assemblies assure you of years of quiet, trouble-free service. 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 and users alike.
Performance and Efficiency
When economy is measured in terms of cubic feet of air per minute per dollar invested, the NBF wall fan exhaust unit is unsurpassed. Coolair’s Type NBF fan is today's best investment. Coolair uses only the most efficient totally enclosed ball bearing motors available.
