Product Details

Industrial axial fan

Energy Efficient Series

Energy Efficient: Helical tri-lobe rotor, 8% higher volumetric efficiency, significant power saving in long-term operation.

Core Configuration: NSK/SKF imported bearings + 20CrMnTi alloy steel gears + piston ring oil-air separation, ensuring oil-free operation.

Strict Testing: 4-hour full-load test before delivery, test report included.

Low Noise Series

Low Noise: Double-layer silencer + sound-absorbing foam, noise below 85dB, environment-friendly.

Aquaculture Special: Anti-corrosion coating + labyrinth seal, 100% oil-free operation, safe for aquatic products.

Easy Maintenance: Only gear oil change every 2000 hours, no other wearing parts.

High Pressure Series

Wear-resistant Reinforced: Thickened casing + hardened flow channel, resistant to particle wear; reinforced flange to prevent high-pressure deformation.

Stable High Pressure: Pressure range 9.8-98kPa, involute profile design, no efficiency loss in high pressure zone.

Multiple Protection: Fully enclosed belt guard + automatic relief valve (overload protection).
