5V hard hat cooling fan
5V hard hat cooling fan
How to know the cooling fans grade?
1.When we choose the fans ,not base on the speed, when the cooling efficiency are same, we choose the one with higher air flow and higher Static pressure.
2.when the air flow reach the cooling demand,we choose the fans with lower speed, Cause lower speed,longer life span.
3.The material of the frame and flabellum ,we choose the PBT not PC. PBT is out of shape at temperature 230 degrees centigrade.PC is out of shape at 120 degrees centigrade.
4.The bearing type:we choose ball bearing. Ball bearing is a rolling friction from metal beads scroll , the contact area is small, the friction coefficient is small; but sleeve bearing is sliding friction ,contact surface is big ,after long-term use, the oil would evaporate, bearing wear and tear, friction coefficient is big, noise level is higher,and life shorter.
5.the wire and the connector. diferent type wire and connector have diferent quality.
6.PCB : the IC quality ,or IC with RD/FG/PWM signal or not.
7.Other special sepecifications.As:fire-proof material, RD signal (Stall warning), FG signal(Detect fan speed value), warter proof and so on.
CEETIFICATE:
CE: have been got the certificate.
UL: About the certificate,we apply after order,because diferent buyers have diferent sepecificaton needed.
ADC fan module advantages:The more installed models: installed in any model at any time, and can installed horizontal or vertical direction. (The framework of the blowers, fans, 2-12 cm can be used)The cooling effect is enhanced: machine connected to the AC fan directly. AC fan itself limited, often can not reach the customer requirements. If it connect connecting the DC fan through the ADC cooling module, the wind speed of the air volume improved significantly, and better ensure the cooling effect of the machine.Long life, environmental protection, no pollution: such this fan kit is almost maintenance-free. Oil and gas pollution-free, The fan use import high-speed, thermostability ball bearings ,hundred percent guarantee non-oil and gas.Low vibration: after a high-precision balance design, testing, calibration, fan's vibration rate is very low.Low noise: high voltage, low noise motor direct drive, can reduce the rotation noise.
1. Technical SupportOur engineering team is dedicated to providing you with the most professional service. If you have any special needs for the fan specifications, please let us know. We will provide you with product design, mold development and qualified samples.
2. Samples and OrdersIf we reach an agreement in product parameters and price, we will send samples for you to evaluate and confirm. We charge no sample fees or shipping fees for samples sent home and only shipping fees for samples sent abroad. Customers’ address details and telephone number are needed.
3. DeliveryWe have an efficient team and achieve elastic productivity by efficient management. We promise that lead time base the producing progress of others after the verification of orders. Some even can be done within10 days.
4. After-sales ServiceAll customers are our friends. We will try our best to learn about your demand for products and applications.
We conduct a customer satisfaction survey every year to learn about customers’ feedback to our products and service comprehensively. All customer feedbacks will be replied within 24 hours.
Whenever any rejects are complained by customers or our internal departments, the Quality Department and Production Department will issue relative reports, make, implement and track relevant analysis and modified programs. The Quality Department holds regular monthly quality meetings to review the quality status and statistical data of this month, so as to develop and improve new objectives and plans.
