key word:
This positive pressure air supply fan is a robust, industrial-grade centrifugal blower designed to deliver reliable, high-volume fresh air supply or positive pressure ventilation in enclosed spaces. It is widely used in laboratories, cleanrooms, pharmaceutical facilities, food processing plants, warehouses, basements, parking garages, and other areas requiring consistent positive pressure to prevent contaminant ingress, maintain air cleanliness, or ensure proper air exchange.
The fan housing (casing) is constructed from thickened galvanized steel sheet with a durable electrostatic powder coating finish, providing excellent corrosion resistance, structural rigidity, and a smooth, attractive appearance. The inlet flange is formed using advanced one-time spin-forming technology, ensuring high precision, no deformation, superior roundness, excellent airtightness, and a clean, professional look.
The impeller features thickened steel blades and a modular pressure-molded hub with optimized aerodynamic twist-curve design, delivering high airflow efficiency, low wind resistance, reduced noise, and balanced operation.
The motor is a premium full-copper coil unit, offering faster rotation speed, lower temperature rise, stable long-term performance, and extended service life even under continuous duty.
Special anti-vibration design incorporates triangular mechanical fixing points to effectively minimize vibration and movement during operation, ensuring quiet and steady performance.
