in close cooperation with a number of scientific research
organizations, Some of these fans have been tested by
Manchine_Building Industry General Machinery Product
Inspect Institute with good performance characteristic and
were recommended by China Refrigeration and Air
Conditioning Industrial Association, and by Chinese
Refr igerat ion Associat ion. Two types of fans are
nominated as national key new products; one type of fans
was listed into Nation Torch project. SYD and SYH Series
fans are licensed to bear the AMCA Seal. "Yilida" was
nominated as Zhejiang province famous trademark. The
products are presently being supplied to more than one
hundred air conditioning equipment manufacturing
companies in China, these companies include York, Trane,
Mcquay, Dunham-Bush, Sinko, Gree, Midea, Hitachi, LG
electronic, Changhong, Bing Shan, Tica, Tong Fang, King,
DunanKangda, Emoson and tecak. They are also being
supplied to customers in Europe, America, Middle East
and Southeast Asia countries. SYP series fans have more
than 55% share of Chinese market and the drain pan
products have more than 45% share of Chinese market.
The Company's guiding principle is to satisfy customer
requirements and expectations by providing them with high
efficiency and high reliability ventilators that are based on
designs using the most advanced technologies and on
manufacturing processed using the most advanced
production equipment. Zhejiang Yilida Ventilator Co., Ltd.
stands ready to cooperate with new and old customers
alike, at home and abroad, in order to promote the

Explanation of
SYB Series Ventilator products
1) Direction of Rotation
SYB Series ventilator can be devided into two direction of rotations, left-hand
rotation(LG) and right hand rotation (RD); Viewing from motor outlet terminal, if the
impeller rotates clockwise, it is called right hand ventilator; If the impeller rotates
anti-clockwise, it is called left hand ventilator.
2) Direction of Air Outlet According to Fig 1, SYB Series ventilator can be made in
four air-outlet direction 0 90 180 270 .

Nominal diameter of
impeller(mm)
SYB series centrifugal fan is kind of
air-conditioning fan. The impeller of
the fan is driven by three phases
external motor. It was developed by
using high technology and with low
noise and compact structure. It
was specially designed for the air-
conditioning. The flow rate and total
pressure range of this series fan is
from 1000m3/h to 20000m3/h and
200Pa to 850Pa. It is the ideal
equipment for air-conditioning and
other kind of ventilator system.

Construction of Product
32005
YILIDA VENTILATOR
SYB Series ventilator consists of scroll, impeller, baseplate (frame), motor, SYB Series
ventilator consists of scroll, impeller, baseplate (frame), motor, shaft sleeve and air outlet
flange.
1)Scroll
The scroll is made of high quality hot-galvanizing steel sheet. The side plates take the
shape according to aerodynamics and make the ventilator volume minimum. On the air
inlet of side plate there is an air-inlet to make the air stream enter the impeller without
loss. The snail plate is fixed on the side plates by way of spot welding or biting as a
whole. On the side plate of the scroll there are a series of holes drilled in advance for
riveting nuts to carry out installation according to air outlet direction needed by the
customer.
2)Impeller
The impeller is made of high quality hot galvanizing steel sheet and is de- signed to a
special configuration according to aerodynamics to make the efficiency highest and the
noise lowest. The impeller is fixed on the middle disk plate and on the end ring with
riveting grippers. The impeller has enough rigidity during continuous rotation with
maximum power. Before leaving factory, All impellers have passed all-round dynamic
balance test according to the Company Standard which is higher than National
Standard.
3)Baseplate(Frame)
SYB Series ventilator baseplate is made of high quality hot galvanizing steer sheet. The
direction of baseplate installation can becarried out according to the different
requirements of customers. Over SYB 315 ventilator frame is made of angle steel and flat
steel. On four sides of the frame there are holes drilled for installation to meet
customers's requirements in different installation directions.
The motor used in SYB series fans are low noise three phase asynchronous motors with
external rotors. The impeller is installed on the external casing of the motor. The motor
rotation speed can be changed by using provided with three -phase voltage regular,
silicon controlled. Voltage regulator, frequency converter and etc. to satisfy changeable
load in system.
4) Motor
5)Flange
The flange is made of hot galvanizing angle steel. The connection of angle steel straps
and the connection between flange and scroll are carried out by using TOX non-welding
technology, thus obtaining fine appearance, enough rigidity and strength. The dimensions
and type of flange are shown in Fig2.

YILIDA VENTILATOR
1)The ventilator performance in this catalogue denotes the performance in standard
conditions. It denotes air inlet conditions of ventilator as follows:
Air inlet pressure Pa = 101.325KPa
Air temperature t = 20
Inlet gas density = 1.2Kg/m3
If the practical air inlet conditions of constomer or the speed of the operating ventilator
changes,the conversion can be carried out according to the following expression:
SYB Series Ventilator
Size and performanceParameter
Where:
*Volume Qo(m3/h), total pressure Po( Pa ), speed n( r/min ), and Nino ( kw) can be obtained
from Performance chart.
*Asterisk ( * ) on the upper right corner denotes the performance parameter needed by the
customers in practical gas inlet conditions.
*The difference in relative humidity is omitted from the above-mentioned formulas.
2) The performance of the sample ventilator is tested in accordance with GB1236-2000. Its
noise index is measured according to GB2888-1991 at the point 1 metre from the inlet.

YILIDA VENTILATOR
1) Matching electric motor power of ventilator denotes internal power plus safety
coefficient of electric motor capacity in special operating condition, it does not denote
the power required during full opening of air outlet. Therefore no-load running of
ventilator without any applied resistance is strictly prohibited in order to avoid burning
out of the motor caused by its operation at over rated power.
2)This fan is restricted for use in areas where air substances are non-corrosive and
non-toxics non-alkaline or where dust partides
