The service quality of industrial fan manufacturers directly affects the effectiveness and lifespan of their products. When choosing an industrial fan manufacturer, it is important to pay attention to the following 7 core service elements to ensure professional support throughout the entire process from pre-sales to after-sales:
1、 Professional pre-sales technical support
On site survey and scheme design
Provide free site measurements (floor height, area, heat source distribution), generate 3D ventilation plans based on CFD airflow simulation software, and specify the number, position, and inclination angle of fans.
Example: A certain automobile factory has a floor height of 12 meters, and the manufacturer suggests through simulation that 6 7.3-meter fans should be arranged in a diamond shape to avoid dead corners of airflow.
Suggestions for scenario based selection
Recommend configuration based on environmental characteristics (such as explosion-proof motors for chemical workshops and stainless steel fan blades for food factories).
2、 Standardized installation service
Security Installation Team
Certified high-altitude operators are equipped with tools such as laser level gauges and torque wrenches to ensure installation accuracy (blade horizontal error ≤ 1 °).
Key item: Steel structure load-bearing verification (proof of factory load required).
Installation acceptance process
Vibration testing (amplitude<0.5mm), noise detection (<50dB), wind speed distribution map (covering the target area).
3、 Warranty and after-sales service commitment
Service project industry standard superior manufacturer standard
The warranty period for the whole machine is 1-2 years. The motor is 5 years and the fan blades are 3 years (such as Hunter)
Response time: Remote diagnosis within 48 hours, on-site within 72 hours
Spare parts supply, regular parts, 15 days of stock availability in the common parts warehouse (72 hour shipping time)
4、 Intelligent operation and maintenance support
Remote monitoring system
Optional IoT module, real-time monitoring of motor temperature, speed, energy consumption, and automatic alarm for abnormalities (such as the Big Shepherd SmartFan system).
Preventive maintenance reminder
Push maintenance schedule based on operating hours (such as changing lubricating grease every 4000 hours).
5、 Training and documentation support
Operation Training
On site guidance on the use of speed controllers and emergency shutdown operations (training signature records must be retained).
technical documentation
Provide both Chinese and English manuals, electrical schematics, and maintenance videos (scan the code to view).
6、 Emergency service capability
Fault classification response
One fault (such as leakage): 2 hours of remote guidance+24 hours on-site;
Level 3 malfunction (such as minor abnormal noise): dealt with within 72 hours.
Backup machine service
The brand provides emergency backup machines (such as Rite Hite's FanExchange program).
7、 Sustainable Service Extension
Energy Efficiency Optimization Service
Provide energy-saving reports during annual follow-up visits (such as a logistics warehouse saving 12000 yuan in annual electricity bills through speed regulation strategies).
Equipment upgrade and renovation
Replace the old fan motor with a permanent magnet synchronous motor (saving over 15% energy).
Avoiding pitfalls guide: Common problems with poor quality services
Only providing drawings without on-site survey → resulting in insufficient actual coverage;
Outsourcing installation to a third party → high security risk;
During the warranty period, on-site fees will be charged. The terms must be clearly defined before signing the contract.
When choosing a manufacturer, it is essential to provide successful cases (industry priority) and service white papers, and include them in the contract's additional technical agreement.
