Model | Blade Diameter/mm | Frequency/Hz | Electric Current/A | Input Power/Kw | Voltage/V | Rotational speed(r/min) | Noise(db) | Air Flow (m³/h) | Size/mm |
NHXL1380 | 1250(50in) | 50 | 1.25 | 1.1 | 380/220 | 44000 | ≤64 | 44000 | 1380*1380*450 |
Blades:The mirror face stainless steel blades are imported from
German,the whole machine goes through balance test.
Blade diameter:1250mm(50" ventilation fan).Blades are formed by
stamping while the angle is suitable,which can make the biggest
airflow as well as the smallest noise and not out of shape nor
rupture during long using term.
Additionally,each set of blades must be tested by balance system
before sold,which will make sure the stable and smoothy work for
the fan.
Hot galvanized sheets.The thickness is 0.8mm and 1.5mm.It increases
the intensity,life length and weight of whole machine.It improves
the stability of the fan.
The special and advanced centrifugal system assures the opening
angle of the shutter so that air flow can be kept on the smooth
high level.It is made of superior quality nylon and a litle
fiberglass,also it is used rivet,which is made of cuprum so that
they will antirust.Column-oriented is made of 304 stanless steel.It
can ensure the shutter opens with the angle of 90 degree when the
while machine runs on the rails.
Demestic motor,Siemens,we will supply according to customer's
choice and suiting for local voltage and frequency.
Installation hole of motor is six angles instead of the
roundness,which can steady the motor better.
Two kinds of belf pulley for selection:Aluminum,Cast Iron.
It is used by aluminium magnesium alloy,light weight,high
intensity.Flank is one-off injection moulded,with aluminium
magnesium alloly,which is ne aerial material,ligh and high-strength
with beautiul shape.
The spring is made of high quality 304 stainless steel,it will be
antirust and non-deformation during long term-using,which ensure to
close the shutters in place.
Being imported from Japan,the Mitsuboshi belt is of top performance
and long using terms wihout any maintaining.
Frame, frames are made of galvanized board, thickness
1.0mm,galvanizing layer 180g/square meters.
Blade, 6 pieces of blades and all the blades are made by stainless
steel, mirror face.
Impeller, casting aluminum alloy impeller.
Bearing of impeller, permanently sealed bearing, size 633313.
Venture, galvanized board, thickness 1.0mm.
Blade tip clearance, 25mm.
Inlet wind protecting net, spraying paint steel wire, thickness

Electrical motor, national-grade aluminum alloy frame motor, 380V,
1.1KW, 50Hz, 3-phase, 4-pole speed, 1410r/m, IP55, class F,
efficiency 90%, top/foot mounted, certification, CE.(motor can be
supplied as demand)
Motor bearing, national grade.
V-belt, A -type belt, imported from Japan.
Shutters, galvanized board, 0.8 mm thickness while the middle piece
thickness 1.0mm. Galvanizing layer .
Opening system, push-pull centrifugal opening system.
Rivets, aluminum alloy and stainless steel rivets.
Cable, 1 meter long, strong robber wire.
Warranty offer, 1 year for the whole machine.
High precision system is assistant by computers, which maximizes
the effectiveness of the fan. Ten strict procedures that consist of
airflow test, noise test, libration test, drive concentric test,
blade RPM test, electric current test and whole machine efficiency
test, dynamic balance test, the thickness of the galvanized sheet
test, the size of the spare parts test, They assure the quality of
the fan.
