F-WH-D-8025M24S
DATA SHEET
Function and Environment Explain
A.
Life Expectancy: 50000 hours for ball bearing, 20000 hours for sleeve bearing,(While fan is operating at rated voltage in room
temperature 25C and relative Humidity15%~65%RH environment)
Locked Rotor Protection:Impedance of motor winding protects motor from fire in 96 hours of locked motor.
B.
C. Dielectric strength:5mA max.at 500VAC 50/60 Hz one minute between frame and (+) terminal.
D. Insulation strength:10Meg OHM min. at 500VDC between frame and (+) terminal.
E.
F.
Test of high & low temperature:Refer to GB/T2658 3.17&3.18.
Packing Vibration Test:Refer to GB/T2658 3.20&3.21.
G. Acoustical noise test:The sound is measured at rated voltage, less than 17dB in the environmental sounds in the vacuum
chamber, from the air volume of the suction side at 1 meter distance from the fan intake of the sound value of the microphone.
Notes
We will not guarantee the products if the applications of our products are exceeded the limitation which is specified on this
specification.
2. In case of changes of the specification specified on this document, a written notice is requested in advance.
3. Please do not touch the blade with the push and never bring the fan with lead wire, the bearing and lead wire may be damaged.
4. No guarantee on the products against the safety problem or failure covers by power dust drop of water or insect.
5. If there is any data or related documentation different from this data sheet, this data sheet is the principle reference.
6. Please do not use the fan in the environment of corrosive gas or liquid or any detrimental gas.
7. Not all fans are provided with the Lock Motor Protection feature. While the fan is in operation please do not lock the fan intentionally
for a long period of time, since the continuous stoppage will result in overheat and thus burnt out the fan.
8. During the installation of the fan please pay substantial attention to possible notice caused by resonance vibration and shock.
9. It is very important to notify that ovoid to drop from 50 cm height when in any movement or operation it will impact the balance of
blade, especially ball bearing structure is avoided to noise down.
10. The torque if the screw which locked the frame should not exceed 10kgf.
