Fire Smoke Exhaust Fan High Volume Axial Fan For Industrial Buildings HVAC Duct Systems
HL3-2A/HLF-6 High Efficiency Low Noise Mixed Flow Fan
* Model No.5~No.9 of HL3-2A/HLF-6 mixed flow fan consists of optimized mixed-flow airfoil impeller, cylindrical/rectangular casing, streamline air inlet and direct-coupled foot-mounted motor. ·
* The impeller is assembled with multi-piece swept mixed-flow blades and central hub, combining high-pressure advantage of centrifugal fan and large-volume feature of axial fan. ·
* These energy-saving mixed flow ventilators are fabricated from premium carbon steel plate; all impellers pass strict static & dynamic balance calibration, with outstanding aerodynamic efficiency, compact volume and lightweight body. ·
* Two structural types available: HL3-2A (cylindrical round flange casing for pipeline inline installation), HLF-6 (square cabinet casing with rectangular flange for duct matching). ·
* Optimized internal runner ensures smooth airflow into impeller to cut wind resistance and reduce operating noise.
HL3-2A/HLF-6 Model Features:
Material Properties
Featured by compact structure, small footprint, high static pressure, big air volume, energy efficiency and low noise, this mixed flow fan can replace low & medium pressure centrifugal fans below 2000Pa. Widely applied for ventilation, air exchange and dust removal in industrial plants, commercial & civil construction projects.
Standard configuration is 380V three-phase general asynchronous motor; explosion-proof variant (B-HL3/B - HLF) equipped with YB flameproof motor and SUS304 stainless steel customized version are optional for corrosive or flammable waste gas exhausting as required.
Benefits
Standard HL3-2A & HLF-6 fan is suitable for conveying clean, non-corrosive and non-explosive harmless air. With explosion-proof motor, the explosion-proof model can exhaust volatile combustible gas. The transported medium cannot contain sticky substance and coarse granular dust, dust impurity ≤150mg/m³ and medium operating temperature ≤80℃.
Fan Structure
Explosion-proof B-type and anti-corrosion F-type mixed flow fans share identical airflow parameters, performance data and installation dimension with standard carbon steel HL3-2A/HLF-6 fan, only driving motor or shell material is modified.
Model Selection
Each model from No.5~No.9 supports multiple speed options to adjust flow and total pressure for different pipeline resistance.
