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.
Â
Â
1.Reasonable cone designing,
low noise, big air flow, strong ventilation, low operating
cost.Â
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.Â
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.
