DC4028G Extreme-Pressure 40mm Fan Advantages
DC4028G is engineered for the most resistance-heavy 40mm cooling paths, combining extreme pressure, high speed, and ball bearing durability.
Extreme 96.96mmH₂O Static Pressure
DC4028G reaches 96.96mmH₂O static pressure, making it suitable for highly restricted cooling paths where standard compact fans cannot move enough air.
25000RPM High-Speed Motor Range
The top-speed model reaches 25000RPM, giving DC4028G the airflow velocity needed for dense ducts, filters, and heat sinks.
30.48CFM Airflow with Deep-Frame Pressure
The fan combines large air volume with pressure-focused design, rather than relying only on open-space airflow.
Ball Bearing for Heavy-Duty Cooling
The ball bearing structure supports high-speed, high-load operation in demanding thermal environments.
YCCFAN DC4028-G Product Overview
Understand the key design details of DC4028-G, including structure, material safety, performance range, and function options.
DC4028G is a 40×40×28mm extreme-pressure DC fan developed for the most demanding airflow resistance conditions in this product group. It is not meant for quiet general ventilation; it is designed to force air through difficult paths.
With 12V/24V models, ball bearing construction, optional control functions, and high-speed performance, DC4028G is suitable for compact high-power, high-density, or ducted cooling designs.
DC4028-G Airflow & Static Pressure Performance Curve
Use the DC4028-G P-Q curve to evaluate airflow and static pressure behavior across different speed levels and cooling resistance conditions.
DC4028G Applications for Extreme-Pressure Cooling
Designed for filters, dense heat sinks, ducts, grilles, and high-power compact systems where ordinary small DC fans cannot maintain airflow.
Get Cooling Support
High-Density Heat Sink Cooling
DC4028G can force airflow through dense fin stacks where lower-pressure fans lose performance quickly.
Filtered or Dust-Protected Systems
Its pressure capability helps maintain airflow through filters, dust covers, protective grilles, or mesh structures.
Server and High-Power Electronics
The fan can support compact high-power electronics where heat density is high and airflow must pass through tight internal spaces.
Ducted Forced-Air Cooling
DC4028G is suitable for directed airflow channels where air must travel through a fixed and resistant route.
Industrial and Telecom High-Load Systems
12V/24V versions make it suitable for industrial electronics, telecom modules, and high-load enclosed systems that require pressure-driven cooling.
