FAQs

What voltage does this motor require?

The motor requires a DC 3V power supply.

What size tubing fits this pump?

This motor is designed to fit tubing with an inner diameter of 3mm (0.12 inches).

Can this be used for high-pressure applications?

No, this is a mini air pump motor designed for low-volume airflow and is not suitable for high-pressure applications.

How do I power the motor?

You will need a DC 3V power source, such as a 3V power adapter or a battery pack configured to provide 3 volts.

What is the main purpose of this motor?

Its primary uses are for aquarium tank oxygen circulation and DIY projects requiring a small air pump.

What are the dimensions of the motor?

The total size of the motor is approximately 45 x 21mm (1.8 x 0.8 inches L*W).

Does it come with a power adapter?

No, the product is just the motor. A separate DC 3V power supply is required.

Troubleshooting

Motor does not run

Verify the DC 3V power supply is connected correctly and providing adequate voltage. Check the wiring connections to the motor's pins for security.

No air is being pumped

Ensure the tubing is securely attached to the motor outlet and the air stone or destination. Check for any kinks or blockages in the tubing. Confirm the motor is spinning.

Motor runs but pumps very little air

Clean any debris from the motor's air intake. Check if the motor is submerged in liquid, which can impede airflow. Ensure the tubing diameter matches the motor's output.

Motor runs intermittently

Check the power source for stability. Loose wire connections can also cause intermittent operation. Ensure the motor is not overheating.

Pros and Cons

Pros

  • Compact and lightweight design
  • Suitable for low-voltage DC applications
  • Easy to integrate with 3mm tubing
  • Durable construction for extended use
  • Versatile for aquariums and DIY projects

Cons

  • Requires a DC 3V power source (not included)

Setup, Compatibility & Care

Setup:

  1. Ensure you have a stable DC 3V power source. This could be a DC 3V power adapter or a battery pack providing 3 volts.
  2. Connect the positive and negative wires from your power source to the two pins on the motor. Polarity typically matters for motor direction, though for simple air pumping, either connection might work.
  3. Attach a length of 3mm (0.12 inch) inner diameter tubing to the air outlet port of the motor.
  4. Connect the other end of the tubing to your air stone or desired application.

Compatibility:

  • Compatible with DC 3V power sources.
  • Designed to fit 3mm (0.12 inch) inner diameter tubing.
  • Not designed for AC power.

Care:

  • Keep the motor clean and dry. Avoid exposing it to water or excessive moisture.
  • Ensure the air intake is clear of debris to prevent blockages and maintain airflow.
  • Periodically check the wiring connections for security.
