Powerful Static Pressure Solution for Restricted Airflow Systems
SZR high pressure DC centrifugal fans are specifically developed for equipment requiring concentrated airflow delivery through narrow ducts, dense filters or high-resistance ventilation paths. The blower system combines powerful static pressure output with stable long-term operating performance.
Pressure-Oriented Design
The fan adopts a reinforced metal housing structure combined with a high-strength centrifugal impeller to improve pressure generation efficiency. Optimized airflow channels help reduce leakage loss and improve airflow concentration through restrictive systems.
The brushless motor system supports stable torque output under heavy pressure loads and maintains consistent ventilation performance during continuous operation.
