NBF Fans

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.

Basic Components

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. Our Type NBF fan is today's best investment. We uses only the most efficient totally enclosed ball bearing motors available.

Screen Houses

The placement of a very thin screen reduces the entrance of pests and diseases and also creates a drop in pressure of the air passing through the screen which reduces plant transpiration. The physical exclusion of the insects from the greenhouse reduces the incidence of direct crop damage and also of insect-transmitted virus diseases. There is also an independent roof layer of polyethylene film which keeps the rains out, while allowing maximum passive ventilation.
