PMD2408PMB1-A(2).GN Performance Features

Powerful Cooling Capacity

Among fans of the same size, the PMD2408PMB1-A(2).GN delivers industry-leading airflow and pressure: 84.1 CFM at 5700 RPM, with a static pressure of 0.74 inch-H-O. Even in high-impedance, densely packed installations, it ensures rapid heat removal.

High-Efficiency Brushless 4-Pole Motor

SUNON’s 2-phase, 4-pole DC brushless motor design offers higher energy conversion efficiency and lower losses than traditional motors. With over 40 years of motor expertise, SUNON DC fans can reduce power consumption by up to 80% compared to conventional AC motors.

Precision Dual Ball Bearing System

The maintenance-free dual ball bearings provide lower friction, better wear resistance, and longer life than sleeve bearings. Even under continuous highspeed operation, the fan runs smoothly, reducing maintenance costs and meeting demanding industrial requirements.

Auto-Restart & Rotor Lock Protection

Built-in auto-restart function: if the rotor locks (e.g., due to debris), the motor automatically cuts power to protect itself. Once the obstacle is cleared, the fan restarts automatically – ideal for unattended environments.

Wide Voltage Operation

Operates from 10 to 27.6 VDC (rated 24V), easily handling voltage fluctuations in industrial sites. The low start-up voltage (10V) ensures reliable startup under various supply conditions.

High Electrical Safety

Insulation Resistance: >10 MΩ between stator and leads (tested at DC 500V).

Dielectric Strength: Withstands AC 500V for 1 minute or AC 600V for 2 seconds.

FlameRetardant Materials

Frame and blades are made of UL 94V-0 flame-retardant PBT, self-extinguishing and reducing fire risk – ideal for electronics and control cabinets.

Low Noise Operation

Noise tested in a semi-anechoic chamber: only 55.2 dB(A). For a 5700 RPM fan, this is excellent noise control, suitable for offices, data centers, and medical devices.

Innovative Dust-Resistant Design

SUNON’s S&C design enhances resistance to dust ingress, prolonging fan life in dusty environments. Optional IP55 rated versions (suffix .IP55) are available for outdoor or harsh conditions.
