A main contributor to high bird stress and low bird weight is
an overheated or poorly ventilated poultry house. Even if
your building is well ventilated, inecient equipment can
blow healthy bird prots right out the window. Cumberland
ventilation systems are the perfect solution.
The BUTTERFLY FAN eliminates the need
for the traditional louver shutter which are
prone to dust buildup. During fan opera-
tion, the air forces the shutter doors open
to provide full fan performance.
• Simple Buttery style shutter structure improves fan performance
and stability.
• Uses a magnetic shutter panel ring to alleviate movement of shut-
ter doors while not in operation. In turn, the sealing area is reduced
50% or more compared to the traditional
louver style shutter, resulting in lower
heating cost during winter months.
• Easy to assemble, angeless cone panels.
A balance of performance, features, and value
come with Cumberland’s 50” & 54” Buttery fans.
