Inverter	1,SAJ brand integrated inverter 2,with phase-lacking and overload protection. 3,Easy control panel,more efficiency. 4,Heat dissipation hole design,anti-dust and prolong the service life. 5,Hidden-type switch,small body great function and nice looking. 7,Removable heat dissipation fan,easy to replace and maintenance
Blade	1,Adopt 6061 aluminum and magnesium alloy integrated molding ,T6 heat treatment.anti- corrosion,high strength,good toughness, fatigue resistance. 2,blade single layer thickness no less than 2.0mm,with 5 extra reinforcement ribs inside, ensure the saftey working.
conection of fan blade and basement	1,Fan blade and basement's connection adopt 45#high strength steel plate with 10mm thickness,anti deformation and breaking. 2,The connection between fan blade and the inserting plate adopts closely insert connection, then fasten by screw bolt,to make sure the safety of fan's working.
fasten part between ceiling and fan	customized fasten part between ceiling beam and fan, adopt 6mm thickness steel panel ,difference ceiling with diffrence fasten part design,make sure 100%safety connection. (T-steel structure:each side fasten two pieces of screw+each side one pieces of screw to avoid moving) (cement structure:each side 3 pcs of M10*100 screw fasten into the cement beam,avoid the vertical force makes screw loosening)
connection safety between motor and motor basement	adopt 11pcs of strong screw to fasten the motor with basement
first protection for avoid blade falling	inside the blade have insert stainless steel rope,the rope will be fasten on the fan blade and basement's connnection part.in case the blade falling still have a rope hanging,will no falling down directly.
sceond protection for avoid blade falling	the stainless steel strips screwed on each fan blade to make a cirle to connect all blades together
fan's falling protection	4 pcs of stainless steel rope connect ceiling with motor at 4 sides,to keep the blance and avoid the fan's falling.
Safty design	1,customized fasten part between ceiling and fan,adopt 6mm thickness steel panel 2,full considerate of the connection safety between blade and motor basement 3,full considerate of the basement's connection safety to avoid any risk of falling 4,adopt high strength fasten screw,load level reach to 12.9 5,4 pcs of stainless steel rope connect ceiling with motor at 4 sides,to keep the blance and avoid the fan's falling. 6,inside the blade have insert stainless steel rope,the rope will be fasten on the fan blade and basement's connnection part.in case the blade falling still have a rope hanging,will no falling down directly.
advantage of 5 blade HVLS fan	1,fan blade in odd number is better for balance. 2,In terms of working efficiency,the less blade quantity the better in efficiency and less operating load

FAQ

FAQ
Q1:Are you a foreign trade company or a manufacturer ?
A: We are a manufacturer, Our factory established since Year 2003,  we specialized in HVLS Industrial Ceiling Fans, cooling fan ,Exhaust Industrial Fan and so on. 

Q2: HVLS fan is joint launched with GREE,what is GREE?
A: Gree is short writing of GREE Electric Appliances Inc of Zhuhai, which was Founded in 1994, listed in Shenzhen Stock Exchange in November 1996, Global Top 500 enterprise and the best air conditioner producer in China. Motor is the motor production department of GREE,also famous for industrial motor's production.

Q3: Why use GREE internal rotor PMSM? What's the difference with external rotor PMSM ?
Internal PMSM: More safety structure:
(1)NdFeB(neodymium iron boron) is inlaid ,structure is stable.  (2) High Anti Grade, IP64   (3) installation has 5 force bearing point, makes the fan stable when there is external force interference.
External PMSM: Less safety structure:
(1) NdFeB(neodymium iron boron) is fixed by glue,easy to fall off.  (2)Motor with heat dissipation holes, unable anti water and dust. (3) wirerope installed on the central pole, all bearing point only in the pole.

Q4:What's the advantage of your HVLS industrial Ceiling fan ?
A: (1) GREE brand intenal rotor PMSM, quality assurance. 
(2) Good quality motor perfect match with special design blade, high efficiency with low energy comsumption. 
(3) blade is R&D with GREE research institue, big and confortable natural wind feeling.
(4) Intelligent intergrated control system , maximun control 48 sets of fan at the same time.
(5) Saftey strcture
(6) excellent after sale service with 5 years warranty.
