30HP 22kw 10Bar 3.2m3/min Fixed Speed Screw Air Compressor

The difference and advantages between a belt-driven screw air compressor and a direct-driven screw air compressor are as follows:

Difference:

1. Structure: A belt-driven screw air compressor is typically connected through belts between the electric motor and the screw compressor, while a direct-driven screw air compressor directly couples the electric motor and the screw compressor into a compact unit.
2. Maintenance: The belt-driven screw air compressor has a more complex structure, requiring regular inspection of belt wear and tension, leading to more frequent maintenance tasks. On the other hand, the direct-driven screw air compressor is relatively simpler to maintain as it does not have belts.
3. Efficiency: The direct-driven screw air compressor usually exhibits higher efficiency since it does not suffer from belt transmission losses, while the belt-driven screw air compressor experiences some energy losses due to belt transmission.

Advantages:

1. The advantage of a belt-driven screw air compressor lies in its flexibility for adjustment. By changing belts of different lengths or types, the operating speed of the screw compressor can be altered to meet varying compressed air demands.
2. The direct-driven screw air compressor, without belt transmission, has a more compact structure, occupying less space, making it suitable for limited spaces.
3. The direct-driven screw air compressor typically consumes less energy as it avoids belt transmission losses and performs well in terms of efficiency.

The choice between the two types of air compressors depends on specific application requirements and site conditions.

Elang Belt Driven Screw Air Compressor

Advantage:

Belt driven, which allows the speed of the rotor to be changed by different diameter pulleys.
1. The belt tension for each operating condition is optimized
2. By avoiding excessive start-up tension, greatly extending the belt working life
3. Always ensure the correct pulley connection
4. Replace the belt is very easy and fast, and do not need to adjust the original settings
5. The whole belt driven system safe and trouble-free operation.

Elang Direct Driven Screw Air Compressor

Advantage:

1. Large displacement: Displacement 10% higher than ordinary piston compressor.
2. Energy-saving: Compared with piston air compressor, this series of models for the new national standard two energy efficiency products, excellent energy saving.
3. Easy to operate: 24 hours unattended all day work, free load automatically start, full load automatically shut down.
4. Strong stability: Under long time working, displacement and pressure stable, no crash phenomenon, low failure rate.
