As the home appliance market moves rapidly toward larger capacity and smarter operation, 11KG triple-drum washer-dryers have become a representative product among premium brands. In such advanced machines, airflow management, heating efficiency, and long-term stability are critical. The HTC09330S12H DC blower fan, developed by Chungfo Technology, has been selected by a well-known appliance brand for its triple-drum washer-dryer to enhance drying efficiency, airflow performance, and overall durability.

1. Project Background: New Challenges of Triple-Drum Structures

Compared with traditional single-drum washer-dryers, triple-drum machines feature more complex airflow paths, multiple heating chambers, and higher demands for stable circulation. The system requires:

Strong static pressure to push air through multi-layer structures

Stable airflow to maintain uniform drying

Quiet operation suitable for premium appliances

Custom signal wires for intelligent temperature control

With more than 20 years of experience in fan manufacturing, Chungfo recommended the HTC09330S12H blower fan, which passed multiple rounds of evaluation and delivered excellent results for the customer.

2. Product Parameters and Performance Advantages

HTC09330S12H Specifications

Voltage: 12V

Speed: approx. 4600RPM ±10%

Current: 0.90A ±15%

Bearing type: Sleeve bearing

Airflow: approx. 26 CFM

Static Pressure: approx. 40 mmAq

Customizable parameters and optional signal wires (FG / PWM / RD)

With strong pressure and stable airflow, this model is ideal for compact airflow chambers and multi-stage circulation systems commonly found in triple-drum appliances.

3. Verified Application Performance

1) Strong Static Pressure for Complex Air Ducts

The 40 mmAq static pressure ensures efficient airflow circulation through heating modules, condensers, filters, and the triple-drum internal passages—an essential requirement for large-capacity dryers.

2) Stable Airflow Ensures Uniform Drying

Its 26CFM airflow helps avoid uneven drying, ensuring rapid moisture removal even when the washer is loaded with heavy fabrics.

3) Reliable Operation in High Humidity and High Temperature

The sleeve bearing offers dependable performance, making it suitable for environments with long drying cycles and continuous humidity exposure.

4) Quiet and Energy-Efficient Performance

Even at around 4600RPM, the HTC09330S12H maintains controlled noise levels, matching the expectations of high-end household appliances.

4. Customization Capability: Chungfo’s Core Strength

Chungfo provides flexible customization services, including:

Tailoring speed, current, airflow, and pressure

Adding FG feedback, PWM control, or RD alarm signals

Durability optimization for hot and humid environments

Structural customization (mounting frames, outlet dimensions, etc.)

For this 11KG triple-drum washer-dryer project, the customer required additional signal wires for better temperature control integration. Chungfo completed the customized version efficiently and passed the full machine verification.
