GD oil-free screw fan from the United States

CycloLower series spiral fan

Representative of American original production and industrial grade fans

The rotor - spiral four blade gate rotor and double blade main rotor are milled from ductile iron and undergo stress concentration reduction and precision power balancing treatment.

Shell - The integral casting shell is sufficient to resist deformation and ensure high-speed and smooth operation of the rotor. Waveform inlet, control airflow stability.

Bearings - All models of products come with wear-resistant bearings. Use double row angular contact bearings and cylindrical roller bearings or single row and double row ball bearings.

Gears - The rotor rotates synchronously through double helical gears, and the precision alloy steel helical gears transmit power quietly and accurately

Oil seal - hydraulic oil seal automatically pushes back lubricating oil to achieve efficient sealing

Air/gas seal - labyrinth shaft seal can effectively control air or gas leakage to the lowest possible level. When the machine processes gas, it must ensure sealing,

At this time, labyrinth seals or mechanical seals can be used

Double splash lubrication - gears and bearings are lubricated through a splash oil system.
