Wheel

Brand New Wheel Design
Patented “Wind Hunter” series mixed flow wheel. Its front disc and venturi are carefully matched to maximize air performance.

Advanced Design

Unique airflow characteristics. Our engineers have repeatedly optimized the wheel with countless CFD simulations.

Advanced Fabrication

The wheel and other fixtures are made from a special designed mold and are continuously welded. Ensuring maximum strength is maintained.

 

High Balancing Level

The balancing level of the wheel is up to G2.5 (AMCA 204) which is much higher than the standard G6.3 required internationally. Stability is greatly increased thus lowering the vibrations and noise.

 

Lowest Noise Level

Testing of the YFISH is conducted in accordance with AMCA 300 Reverberant Room Method for Sound Testing of Fans. It is proven that the YFISH has the lowest noise level among the other products with the same parameters in centrifugal and axial fans.

Product Features

Performance Characteristics
The mixed flow fan has larger air volume over the centrifugal fan and higher air pressure over the axial fan. When placing them under the same working conditions, the mixed flow fan has more advantages over the others in terms of performance and noise level.

High Efficiency

The design of the wheel and guide vane has been repeatedly optimized to assure high efficiency, leakage free and low turbulence.


Better Sound Proofing

The noise of the mixed flow fan is determined by its structural design and changes in acoustical power (see fig. below). The noise generated in each air volume segment is much lower than the axial and centrifugal fan with low acoustical level (62.5-250Hz).

Aluminum Frame Design

The frame of the YFISH is made of heavy duty aluminum. It is very light weight and has the best sealing over the others. Additional sound proofing accessories (double acoustical layer or foamed rubber acoustical lining) can be added easily upon request. 


Flexible Direct or Belt Driven Option

-- Direct driven type has six different blade angles available for selection. A solid low maintenance product designed for delivering efficient air flow.

-- Belt driven type has effective blade angle. Since the motor is located outside, maintenance work or replacement can be carried out easily.

Mutiple Air Directions Design

4 different air exhaust directions  can be chosen in direct drive type and 7 in belt drive type. Makes it more flexible to the actual working environment.

Pulleys

The pulleys shall be iron casted to provide long life and durability. They shall be factory set to the required RPM and adjustable for final system balancing. Drive belts and pulleys shall be sized for 150% of the fan operating brake horsepower, and shall be readily and easily accessible for service, if required.

Belt

Belt shall be oil resistant and static free.

Bearings

Standard bearings shall be ball or roller type, grease lubricated with a basic rating fatigue life (L-10), in excess of 80,000 hours at each level’s maximum operating speed. Renowned brand name such as FYH and SKF shall be used to ensure reliability.

Belt Cover

The belt shall be covered by semi-closed belt guard to prevent accidental injuries.
