Q&A Part

What is the service life of the fan?
It can be used normally for 5 to 10 years. In case of any quality issues, we offer a one-year replacement service and provide a
full warranty throughout the process.

Can the labels, packaging and design of your products be customized?
Yes, we offer customized services related to these.

What is your monthly production capacity?
The production capacity of our factory is 8,000 units per month.

What is your initial order quantity?
There are no restrictions. Customers are of all sizes. No matter how many items you order, we will provide high-quality products
and excellent services.

How to ensure quality?
Strict process control and a professional product quality inspection team ensure product qualification rates. Additionally, our
comprehensive after-sales support system assumes full responsibility for any quality issues during product usage.

May I obtain a sample for quality inspection?
Yes, we offer samples.

Can we issue an invoice? When will the invoice be sent out?
Our fans provide invoices. After the purchase, the fans will be dispatched first. After receiving the goods and confirming they
are correct, personal ordinary invoices can be applied for electronic invoices directly in the platform order. For VAT invoices,
please provide the relevant materials to the customer service for registration. Generally, the invoices will be issued within
10-15 days.

What can be done to prevent rainwater, insects, and birds from entering the fan?
It is recommended to install self-closing louvers. When the fan is turned off, the outlet louvers will automatically close to
prevent rainwater and insects/birds from entering.

How to choose the model of the fan?
Based on the ventilation volume, the ventilation volume = area * height * ventilation frequency / 0.8. Here, the ventilation
frequency is determined according to the actual rated value. In ordinary factories, it is around 8-12 times. The ventilation
volume is selected based on the calculation results and the parameter table. It is recommended to contact our customer service
first for a more accurate recommendation.

Are there any other explosion-proof accessories available for sale?
We offer various accessory products such as explosion-proof pipes, explosion-proof junction boxes, explosion-proof switches, and
explosion-proof distribution boxes. If you have any questions, please feel free to contact our customer service.

Can the fan be linked with the smoke sensor, temperature control switch, etc.? How to operate it?
Sure, dear! All you need to do is install a relay at the top of the fan, and then control the opening and closing of the relay
using smoke sensors, temperature controllers, etc.

Are there any specific requirements for the installation location of the fan?
The fan is a rotating machine. It is recommended to install it in a position that is not easily accessible to people. Moreover,
the hot air rises, so installing it at a higher position can help improve efficiency. Another very important point is to ensure
that the fan is installed stably and firmly.
