Engineering Excellence

1. Dual-Inlet Turbodynamic Design

· Forward-curved radial blades with aerodynamic contouring optimize CFM output and static pressure stability for ducted HVAC/industrial networks.

2. Industrial Durability Architecture

· Impeller options: Anti-corrosion galvanized steel (standard) or ASTM-certified stainless steel (customizable).

· Precision-balanced 220V/380V AC motor (IP55 rated) sustains 2600–3000 RPM under continuous operation, minimizing harmonic vibration and noise (<68 dB).

Operational Versatility

· Critical Infrastructure Support:
▶ High-temperature exhaust management in power plants & turbine cooling systems
▶ Particulate filtration for foundries, welding shops, and chemical processing units

· Large-Scale Climate Control:
▶ Cross-ventilation in warehouses (up to 10,000 m³/hr airflow)
▶ Data center cooling with ±2% airflow consistency across duct networks

Quality Validation Protocol

· Certifications: CE, UL, RoHS compliance; ISO 9001 manufacturing standards.

· Pre-Deployment Testing:
▶ Dynamic balancing (ISO 1940 G6.3 grade)

B2B Procurement Benefits

· Cost Optimization: Tiered pricing for bulk orders (MOQ: 10 units; FOB discounts up to 15%).

· Custom Engineering: Adjust impeller diameter (200–1200 mm), voltage specs, and material alloys per ANSI/AMCA guidelines.

· Global Shipping: Doorstep delivery via air/sea freight with CIF documentation support.
