What are the models of the terminals?

Terminals are connectors commonly used between the power supply fan’s wires and the circuit board. Depending on the specific matching interface, there are different terminal models available. Common terminal models include 2.5 2-pin, 2.0 2-pin, 2.5 3-pin, and 2.0 3-pin, as shown in the figure below.

Which mode of transportation can we choose?

All available modes of transportation—express delivery, air freight, or sea freight—are acceptable. We can use either the designated shipping company or our own freight forwarder for transportation. We provide end-to-end tracking of your shipment until it arrives.

How long can your wire be?

The wire length and terminals can be customized according to your requirements. We only need to confirm the terminal image and the wire grade (the default wire length is 200 meters).

What functions can we choose for the fan?

Optional features: auto-restart, speed detection, shutdown alarm, moisture protection, PWM function, temperature control, and more.

If the goods I want aren’t exactly the same as yours, could you make some adjustments based on my requirements?

Yes, if you can’t find the product you need, our company has a team of professional technical researchers. When your order reaches a certain quantity, we can customize DC fans according to your specifications.

Can I get a test sample before placing the order?

That’s right. We recommend that our customers first obtain samples of the fans they need for quality testing.

What information do you need to get a quote?

Generally, we need information such as company details, fan type, quantity, dimensions, voltage, and airflow rate to help you select the right or a similar fan and provide a quote.
