Product features

Advanced sweep forward blade

Apply the latest aerodynamics lab results 

Blade balance class G2.5 (AMCA)

Smooth surface blade makes easy air entering 

Reasonable design of edge dip angle can reduce turbulence efficiently 

Ensure low noise under high air volume condition 

Square casing design

Easier to make holes on the wall 

Single contour plate with level support beam, the structure is simple and reliable 

Reliable motor plus free lubrication 

Motor in middle of airflow: good for heat dissipation

Free of lubrication: no maintenance is need, suitable for high place installation 

No belt for repeated change 

Complete set of spare parts

Rain cover: exhaust angle 45°, supply angle 90°

Insect proof net: prevent the insects flying into the workshop 

Gravity type check valve: ensure a closed system when the fan is closed 

Design stress be tested for long time work intensity 

Accurate reinforcing bar siting after repeated test 

The blade terminal amplitude can be reduced 

Prevent blade deformation under long time work  

Naming rules 

45°or 90°rain cover 

Exhaust fan can use 45°rain cover, and the air outlet can be equipped with bird proof net. 

Gravity type check valve 

Less weight and air resistance loss with aluminum structure

Anti-explosion structure 

The anti-explosion type fan (model 250-550) use aluminum blade, (model 600-900) use steel blade and anti-explosion motor. The explosion class has reached AMCA Spark C class.
