PRODUCT PRESENTATION

SANYO DENKI San Ace 38 High-Efficiency DC Fan – 9HVA0312P3G001 | 38x28mm, 12V, 30,000 RPM, 1300Pa Static Pressure, PWM Control

Product Overview

The SANYO DENKI 9HVA0312P3G001 is a high-efficiency member of the San Ace 38 series, designed for applications requiring strong airflow and moderate static pressure in compact spaces. Operating at 30,000 RPM, it delivers an airflow of 0.71 m³/min (25.1 CFM) and a static pressure of 1,300 Pa (5.20 inchH₂O), making it suitable for general-purpose industrial cooling where balance between performance and noise is required.

Equipped with PWM speed control and a pulse sensor, this fan allows precise thermal management and real-time rotation monitoring. Its plastic frame and impeller ensure lightweight durability, while compliance with global safety standards makes it ideal for telecommunications, medical devices, and automation equipment.

Note: This model operates at 64 dB(A) — quieter than high-speed variants — making it suitable for environments where moderate noise levels are acceptable.

Key Features

Balanced Performance: Delivers 1,300 Pa static pressure and 25.1 CFM airflow — ideal for medium-resistance cooling paths.
Efficient Speed Control: PWM interface enables dynamic speed adjustment from 0% to 100%, reducing power consumption during low-load conditions.
Real-Time Monitoring: Built-in pulse sensor provides RPM feedback for system diagnostics and failure detection.
Global Compliance: Meets UL, CSA, EN, and RoHS standards; recognized as an Eco Product by SANYO DENKI.
Wide Temperature Range: Operates reliably from -20°C to +70°C.
Compact Form Factor: Standard 38mm x 38mm x 28mm size fits most industrial enclosures.
Ribbed Design: Enhanced structural rigidity for vibration resistance.
