Have you ever felt the uncomfortable heat building up in your car seat on a long drive, even with the AC blasting? While traditional air conditioning cools the cabin, it often fails to provide direct relief where you need it most: on your back and legs. This persistent “hot seat” problem can turn an enjoyable journey into an irritating experience, leading to discomfort, fatigue, and even impacting driver focus. Effectively addressing this thermal challenge in car seats is crucial for enhancing overall driving comfort and elevating a vehicle’s perceived quality.
To combat the pervasive issue of car seat discomfort, we are proud to introduce MEGA’s MG9720H12B blower, the core component for superior seat ventilation solutions.
MG9720H12B Specifications

The MG9720H12B boasts a compact dimension of 97x97x20mm. Despite its small stature, it delivers an impressive maximum airflow of 20.47 CFM (0.579 M3/Min), ensuring efficient air circulation where it matters most. Operating at a standard 12VDC rated voltage, this blower integrates seamlessly into existing automotive electrical systems.
Engineered for Endurance: Reliability and Advanced Safety Features Durability is paramount for automotive applications, and the MG9720H12B is built to last. It offers a remarkable life expectancy of 70,000 hours at 35°C. Furthermore, it incorporates critical safety features, including locked rotor protection: the fan automatically powers off if locked for 1 second at rated voltage, attempting to restart after 2 to 6 seconds. Polarity protection ensures the circuit remains open if Vcc and GND are reversed and prevents burning within 5 seconds in such an event. These robust features guarantee stable and safe operation over extended periods.
Quiet Efficiency: Optimal Noise and Static Pressure Acoustic comfort is a key consideration in vehicle interiors. The MG9720H12B operates at a low noise level of 54.5dB, ensuring it cools effectively without disrupting the quiet ambiance of the cabin. Its maximum static pressure of 30.5 MmH2O (298.9 PA) enables it to efficiently push air through the intricate internal structures of a car seat, providing consistent and uniform ventilation.
We understand that every automotive brand and vehicle model possesses unique design philosophies and functional requirements. Consequently, off-the-shelf fan solutions rarely provide a perfect fit. This is precisely why MEGA is committed to offering highly customized services.

Beyond Generic Solutions: The Imperative for Automotive Customization Car seat design is inherently complex, involving intricate internal structures, specific material choices, and ergonomic considerations. A generic fan simply cannot meet the precise demands for tailored airflow, optimized noise reduction, and seamless integration.
