Technical Specification of VSD Screw Air Compressor
Air Compressor Air-End
The world's highest-quality screw compressor, featuring high efficiency and low speed. The rotor utilizes a third-generation 5:6 tooth profile, the world's most optimized tooth profile design, resulting in low noise, low energy consumption, low maintenance costs, high reliability, and long life.
Motor
This motor, specifically designed for low-speed compressors, features SKF bearings, Class F insulation, and IP54 protection, ensuring smooth operation. Efficiency is 3-5% higher than comparable products. The direct-drive model utilizes a 1:1 direct drive, eliminating the need for a speed-increasing gear. The main unit boasts a large size, low speed, low noise, reliable operation, and long life.
Oil Filter
The rotary oil filter utilizes high-end aviation materials and is 20% more efficient than traditional filter elements, effectively extending the main motor's normal service life.
Oil Separator
This unit features a large-capacity oil-gas separator, high-quality oil-gas separation elements, and a gas-liquid filter element. Utilizing advanced three-stage oil-gas separation technology, the oil content is controlled below 2ppm, ensuring high compressed air quality.
Inlet Valve
Advanced inlet valve design with a 0-100% air intake adjustment range and a capacity control valve ensures low pressure drop, stable operation, and long service life.
Air Filter
Adopting a high dust holding capacity and low flow resistance design, it filters out fine solid particles in the air, achieving a dust removal efficiency of up to 99.5%, ensuring the normal operation and economical service life of all system components.
Cooler
Adopting an extra-large heat exchange surface, it improves cooling efficiency and effectively prevents overheating. The interior wall is treated with anti-corrosion treatment to withstand even harsher operating conditions and extend service life.
Axial Flow Fan
Low-speed fan for a longer service life. The cooler and fan are independently removable, providing a 20% heat dissipation margin. The optimal combination can withstand ambient temperatures of 50°C.
Keeping Your Business Energy Efficient
The VSD compressor is only ever running in the way that you need. This efficiency can result in up to 50% energy savings compared to fixed-speed models. This ability to reduce energy costs can help you to cover the price of the variable speed air compressor, often much quicker than you think.
Stopping the Need to Unload
As VSD air compressors can be started or stopped at the point of full system pressure, you are able to avoid the need to unload which will reduce energy cost and power consumption as well as allow you to save time. This is particularly useful in applications with frequent stop-start cycles.
VSD Air Compressors Mean No Idling Time
Unlike a fixed speed compressor, VSD air compressors sell themselves on being able to meet your compressed air demands in the way you need. This eliminates the inefficiencies and wear associated with idling, extending the lifespan of critical components. This means that variable speed drive technology requires no idling time, offering efficient controls when you need them the most.


Zero Blow-Off Loss with Variable Speed Compressors
When you have fixed speed compressors, you will find that your system needs to blow off air to function in the way you need. This type of blow-off will no doubt increase your energy bill. A VSD compressor adjusts seamlessly, ensuring minimal waste and optimal performance under varying loads. A VSD compressor makes sense in this situation as it can minimise sudden spikes and ensure that your flow demand increases and decreases as you need it with no blow-off needs.
No Need To Worry About Power Company Penalties
Fixed speed air compressors run the risk of peaking at high levels of amperage, resulting in penalties from power companies that increase costs. VSD air compressors mitigate these risks by maintaining consistent energy consumption and avoiding demand charges.
Variable Speed Air Compressors Offer Consistent Air Pressure
VSD compressors reduce pressure drops and enhance overall system efficiency by maintaining pressure within optimal ranges. The great thing about the VSD compressor compared to the fixed speed compressor is that the consistent pressure can be run much lower and allows you to increase your energy savings while getting the best results.
