Large Capacity Square Centrifugal Extractor Fan with TUV certificates

Wheel

• Effect of the 4^th generation Wind-Surfer™ wheel series
-- Excellent aerodynamic characteristics and noise characteristics.
-- High-efficient area width without overloading.
-- Balance quality grade up to G2.5(Typical products are balanced to G6.3 only).
• Air performance design
-- Optimized design of CFD flow field simulation,repeatedly validated.
-- Front disc and inlet venture tube according with flow field characteristic.
-- Flow passage control:matched each other to restrain the air flow better.
-- Optimize the blade angles.
• Structure performance design
-- Stress analysis of FEA to improve performance.
-- Selected the strengthen structure according to different specifications to improve reliability.
-- Using riveting technology to avoid stress.
• Improved wheel
-- Continues improvement:The wheel has the 4^th generation.
-- Compared with the 3^rd generation:Performance increased by 5-10% in the same parameters.
-- Compared with the 3^rd generation: Noise reduced 2-3 dB(A)in the same parameters.
• Advanced process
-- Inlet venture tube & Front disc:spun process to ensure streamlines aerodynamic characteristics.
-- Inlet venture tube: replace bell mouth to ensure smooth air flow.
-- Blades:once punch forming to ensure process quality.
-- Tooling:dedicated fixture to ensure precise install of the blades.

Large Capacity Square Centrifugal Extractor Fan with TUV certificates

Product Feature

• Wide performance range and more economic
-- 4^th Generation Wind-surfer Centrifugal Wheel: low noise while pressurizing compare with 3^rd generation.
-- Maximum wheel diameter is 1 meter,reduce fan quantity and primary investment.
-- The scroll is saved and the cabinet size is reduced.
• Centrifugal in-line:obvious advantage in RPM and noise
-- Compare with axial/mixed flow fans rotation speed is reduced 20-30%.
-- The sound pressure level range reduced by 10-15 dB(A).
-- Fundamental way to reduce noise.
• Plug fan structure
-- Plug fan directly suck air into wheel and pressurize:air flow pattern improved.
-- Direct drive no dust generated:suitable for clean rooms of wafer fab,pharmaceutical and food industry.
-- AMCA Seal:sound and air performance certified.
-- The sound & air performance is approved by AMCA.
• Sound & Air Performance Seal is applied to each fan
-- Square casing with multi-discharge,easier to connect.
-- Square inlet/outlet sleeve flange as standard accessories :round/square convention duct is not needed.
-- Duct connection cost reduced ,and job site working time saved.
-- Motor can be multi-position.
-- Multi-discharge:More convenient and flexible for design & construction.
