Our company is the professional
manufacturer of butterfly cone fan in
China.
1.This fan adopts advanced frontward open
system,butterfly type,with two semicircle shutter doors,wind
resistance is small,good air-tightness and high
efficiency.
2.For the cone part,adopt new design,plug-type
connection,not need many bolts and nuts for tightening as
before,intensity of labor is reduced,also improve aesthetic
results of fan.
3.The belt tensioner device made of aluminum-magnesium
alloy,non-deforming,long service life.This device make the belt
inside tight up,effective for avoiding the belt distortions in
reverse direction,so prolong the belt life time,saving
cost.
4.When hte two semicircle shutter doors close,the rubber
sealing ring make good airtightness.In different condition,not
run all the fan,the air could pass through the space of stop
fan,use this type fan,could avoid this problem.Ensure air pass
through the evaporative cooling pads or air inlet only,so that
greatly improve teh fan efficiency,(as compared with different
type of same size fan,improve efficiency ****0%)
5.The fan motor installed on the top left
corner,effective protection of the motor.Avoid wind
resistance.And the motor panel connection is reasonable,fixing
fan frame more stronger.
1.Reasonable cone
designing, low noise, big air flow, strong ventilation, low
operating cost.
2.Imported bearing,
high-strength, low noise, durable.
3.Using air downstream
principle, pvc shutter or aluminum shutter, antioxidant, light
weight, no distortion, open and close sweeyiy, prevent backflow
of air.
4.High-strength more
high-gluten strength aluminum-magnesium alloy wheel, light
weight, high strength, toughness good.
5.6 pieces stainless steel
blades, no distortion, nibreaking, aesthetic
durability.
6.There are two types of
fan house, slant wall type, upright wall type, could satisfy
varieties need of different customers.
7.The high efficient and
energy-saving motor passed the national CCC
certification.
