Operating at 220 volts AC with a power rating of 370 watts, this blower fan is ideal for applications requiring high airflow, such as cooling, ventilation, and air circulation in industrial, commercial, and residential settings. Its robust design ensures reliable performance in demanding environments.

• Industrial equipment cooling
• Ventilation systems in factories and workshops
• Air circulation in HVAC systems
• Dust extraction and filtration systems
• Home appliances requiring high airflow

Below are the key technical details and pin configuration for the Blower Fan (AC220V 370W):

The blower fan typically has a simple wiring configuration for AC power input. Below is the description of the wiring:

Note: Ensure proper grounding to avoid electrical hazards.

1. Power Connection:

   • Connect the live (L) and neutral (N) wires of the blower fan to the corresponding terminals of the AC mains supply (220V AC).
   • Ensure the ground (G) wire is securely connected to the earth terminal for safety.

2. Mounting:

   • Securely mount the blower fan in the desired location using screws or brackets.
   • Ensure there is sufficient clearance around the fan for unobstructed airflow.

3. Control Options:

   • For basic operation, the fan can be directly connected to the AC mains.
   • For variable speed control, use an appropriate AC fan speed controller compatible with the fan's specifications.

4. Testing:

   • After installation, switch on the power supply and verify that the fan operates smoothly without unusual noise or vibration.

• Safety First: Always disconnect the power supply before installation or maintenance.
• Voltage Compatibility: Ensure the power supply matches the fan's rated voltage (220V AC).
• Overcurrent Protection: Use a fuse or circuit breaker to protect the fan from overcurrent conditions.
• Environment: Avoid using the fan in environments with excessive moisture, dust, or corrosive gases unless it is specifically rated for such conditions.
• Maintenance: Periodically clean the fan blades and housing to maintain optimal performance.

While the blower fan operates on AC power and cannot be directly controlled by an Arduino UNO, you can use a relay module to control the fan's on/off state. Below is an example Arduino code to control the fan using a relay:

// Arduino code to control an AC blower fan using a relay module
// Ensure the relay module is rated for 220V AC operation

const int relayPin = 7; // Pin connected to the relay module

void setup() {
  pinMode(relayPin, OUTPUT); // Set relay pin as output
  digitalWrite(relayPin, LOW); // Ensure the relay is off initially
}

void loop() {
  // Turn the fan ON
  digitalWrite(relayPin, HIGH); // Activate the relay
  delay(5000); // Keep the fan on for 5 seconds

  // Turn the fan OFF
  digitalWrite(relayPin, LOW); // Deactivate the relay
  delay(5000); // Keep the fan off for 5 seconds
}

Note: Use caution when working with high-voltage AC components. Ensure proper isolation between the Arduino and the AC circuit.

1. Can I use this fan with a lower voltage supply?

   • No, the fan is designed for 220V AC operation. Using a lower voltage will result in improper operation or failure to start.

2. Can I control the fan speed?

   • Yes, you can use an AC fan speed controller compatible with the fan's specifications.

3. Is the fan waterproof?

   • Unless specified in the datasheet, the fan is not waterproof. Avoid using it in wet environments.

4. What maintenance does the fan require?

   • Periodically clean the fan blades and housing to remove dust and debris. Check for loose connections and ensure proper grounding.

By following this documentation, you can safely and effectively use the Blower Fan (AC220V 370W) in your projects and applications.
