Double Inlet Cooker Hood Fan

The Double Inlet Cooker Hood Fan is a high-performance centrifugal blower designed specifically for residential range hoods, integrated cooktops, and indoor air extraction systems.

By integrating a dual-intake impeller configuration, air is drawn simultaneously from both sides of the volute housing. This balanced intake architecture significantly increases volumetric airflow rate, enhances static pressure capabilities, and reduces acoustic turbulence compared to single-inlet blowers.

Manufactured via automated assembly lines and verified through precise dynamic balancing, our blowers provide reliable continuous operation for global home appliance manufacturers and equipment developers. We support comprehensive engineering customization to fulfill localized voltage, dimensional, and performance requirement specifications.

Dual-Intake Aerodynamic Efficiency
The dual-inlet architecture doubles the effective air intake surface area without expanding the overall physical width of the fan housing.

Delivers superior air extraction speed under heavy kitchen grease and steam loads.

Generates sufficient static pressure to overcome resistance in extended exhaust ducting.

Reduces internal air turbulence, eliminating harsh operational pitch and whining noises.

 

Advanced Motor Drive Systems
Engineered for continuous duty cycle operations with minimal power dissipation.

AC Motor Option: Cost-effective, robust performance for standard range hood configurations.

BLDC Motor Option: Stepless speed regulation, up to 50% energy consumption reduction, and lower internal operating temperatures.

Built-in thermal cut-off switches protect motor windings under abnormal blockage conditions.

 

Flexible Engineering Customization
Direct physical and mechanical adaptations engineered to match specific range hood chassis designs.

Custom housing mounting flange dimensions and bracket geometry.

Tailored aerodynamic performance curves targeting specific pressure-airflow operating points.

Variable wire harness lengths, customized terminal connectors, and quick-plug interfaces.

 

 

Residential Range Hoods: Chimney hoods, under-cabinet hoods, island extractors, downdraft cooking units, and integrated stoves.

Domestic Air Exhaust: Inline duct boosters, heat recovery ventilation units, and centralized residential exhaust stations.

Light Commercial Ventilation: Commercial kitchen smoke extractors, air curtain blowers, and specialized enclosure cooling units.
 

 

Our production infrastructure is designed for precision, scalability, and repeatable manufacturing accuracy across high-volume orders.

High-Precision Injection Molding: Automated production of balanced impellers using fire-retardant polymers.

Automated Motor Stator Winding: Precise control over copper winding density ensuring uniform electrical characteristics.

Tooling Development: In-house design and fabrication of plastic injection molds and metal stamping dies to accelerate custom project prototyping.

 

 

Two-Plane Dynamic Balancing: 100% of manufactured impellers undergo automated dynamic balancing to eliminate shaft vibration and bearing wear.

AMCA-Standard Airflow Testing: Aerodynamic performance curves and static pressure profiles are verified using specialized wind tunnel test rigs.

Acoustic Chamber Verification: Sound pressure levels and harmonic frequencies are recorded inside semi-anechoic testing facilities.

Inline Electrical Safety Inspection: Every assembled fan undergoes high-voltage insulation resistance testing and rotation validation prior to packaging.
 

 

We ensure all component materials align with international environmental and electrical safety directives.

Flame-Retardant Materials: Housing and impeller resins meet UL94 V-0 or V-2 self-extinguishing safety specifications.

Hazardous Substance Restriction: Raw materials fully conform to RoHS and REACH environmental guidelines for global distribution.

Thermal Safety Compliance: Motor insulation systems are rated to withstand elevated ambient temperatures common in overhead cooking environments.

 

 

To prevent mechanical deformation or impeller misalignment during ocean and air transit, strictly regulated packaging procedures are executed.

Internal Shock Protection: Customized, high-density molded foam trays and corrugated dividers securely anchor each blower.

Heavy-Duty Export Outer Cartons: Double-wall corrugated shipping boxes engineered to endure multi-layer stacking pressure.

Palletization: Reinforced wooden or plastic pallets, completely film-wrapped and edge-protected for container transport.
