Industrial Centrifugal Cooling Fan for Concentrated Airflow Applications
SZR's High Pressure DC blower series is engineered for thermal systems requiring focused airflow delivery and elevated static pressure performance. The blower structure is suitable for compact ventilation channels, restricted airflow paths and heat-intensive electronic assemblies.
Air Pressure Characteristics
Unlike conventional axial cooling fans, the centrifugal airflow design concentrates air output into narrow channels, improving cooling efficiency inside enclosed equipment structures.
The optimized impeller geometry increases static pressure capability while maintaining stable airflow continuity during long-duration operation. The blower motor adopts brushless DC technology with low power consumption and reliable rotational stability.
12V and 24V DC operating platforms are available for industrial automation and electronic cooling integration.
Structural Design
The housing structure utilizes flame-retardant engineering thermoplastic material with enhanced dimensional stability under elevated temperatures.
The blower wheel is dynamically balanced to minimize vibration during high-speed operation. Internal copper winding and precision bearing configuration improve operational lifespan and reduce maintenance frequency.
Compact outlet positioning supports direct airflow guidance for localized cooling applications.
