Product Materials & Structure
The DC Blower 4020 is built using top-grade, industry-certified materials to ensure reliable performance and long lifespan:
Housing Material: Flame-retardant PBT (Polybutylene Terephthalate) with 30% glass fiber, UL94V-0 rating for high heat resistance and structural strength.
Impeller: Balanced PBT impeller, precision molded for aerodynamic efficiency.
Bearing System: Dual ball bearing or sleeve bearing options available, both ensuring smooth rotation and reduced wear.
Motor: Advanced brushless DC motor, designed for energy efficiency and minimal electromagnetic interference (EMI).
This robust material combination contributes to the fan’s excellent vibration resistance, thermal stability, and low acoustic footprint, even under continuous high-speed operation.
Application Scenarios
The DC Blower 4020 is widely trusted in a range of smart and compact appliances. Its high airflow performance and quiet operation make it especially suitable for:
