Economical, Practical, Effective
Coolair’s 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. Coolair’s
Type NBF fan is today's best investment. Coolair
uses only the most efficient totally enclosed ball
bearing motors available.
