Fixed Speed Screw Air Compressor
Product Description
Controller
Adopts the international top-level third-generation asymmetric wire twin-screw air end, adheres to the exquisite manufacturing process, adopts the peak high efficiency low-pressure, high-efficiency tooth shape and the axial air inlet design.
Inverter
The standard is equipped with high frequency reactor, effectively reducing the frequency converter and the external magnetic field dry reactance.
Cooler
The heat exchanger uses high-quality raw materials and a unique internal channel design, which increases the heat exchange area and can effectively dissipate heat for the air compressor.
Oil filter
Adopts high-density filter material, the surface is treated with nano-electroplating.
Oil separator
The high-quality air-oil separation element and gas-liquid filter element are equipped with advanced three-stage air-oil separation to keep the oil content below 3ppm to ensure the output of high-quality compressed air.
Air end
Adopts the international top-level third-generation asymmetric wire twin-screw air end, adheres to the exquisite manufacturing process, adopts the peak high efficiency low-pressure, high-efficiency tooth shape and the axial air inlet design.
Fan
The fan uses a large fan design to effectively enhance the fan's heat dissipation effect.The motor adopts a special internal design to adapt to harsh working conditions.
Motor
The motor uses high-performance motors of well-known brands. Permanent magnet synchronous motors (PM motors) use high-performance NdFeB permanent magnets which will not lose magnetism under 200 ° and its service life reaches as long as 15 years.
Intake valve
Adopting the world famous brand air intake valve, it can automatically adjust theair volume by 0-100% according to the requirement of the system air quantity. It promises small pressure loss, stable action and long life consequently reduced operating costs.
Air filter
Adopting a design with high dust holding capacity and low flow resistance, which can filter out tiny fixed particles in the air. The dust removal effect can reach 99.5%, ensuring the normal operation of the components of the system and extending the service life.

Advantages of Dukas Screw Air Compressor
1. Intelligent Control System with big touch screen
Direct display of discharge temperature and pressure, operating frequency,current,power,operating state.Real time monitoring of discharge temperature and pressure, current, frequency fluctuations.
2. Wide Working Frequency Range To Save Energy
Frequency conversion ranges from 5% to 100%.When the user s gas fluctuation is large, the more obvious energy saving effect and the lower the low-frequency running noise, applicable to any place.
3. Small Start-up Impact Protect Factory Power System
Use frequency conversion permanent magnet motor, start smooth and soft.When the motor starts, the current does not exceed the rated current, which does not affect the power grid and the mechanical wear of the main engine, greatly reduces the power failure and prolongs the service life of the main screw machine
4. Humanized Canopy Design Easy To Maintain
The compressor features a solid construction hence is build to last. All the parts of the air compressor are made of quality material that will last for years.
Apart from refilling the lubricant, you only need to perform other basic air compressor maintenance practices.
5. The Latest Generation Super Stable Inverter Keep Optimal working mode
Constant pressure air supply, air supply pressure is accurately controlled within 0.01Mpa.Constant temperature air supply, general constant temperature set at 85℃, make the best oil lubrication effect and avoid high temperature to stop.No empty load,reduce energy consumption by 45%, eliminate excess pressure.For each 0.1mpa increase of air compressor pressure, energy consumption increases by 7%.Vector air supply ,accurate calculation, to ensure that the air compressor production and customer system air demand at all times to maintain the same.
6. Supply Clean Compressed Air
The equipment working with compressed air are generally focus on the air pressure, but many people ignore that in addition to the pressure of compressed air, its cleanliness affects the life of the equipment. Such as the use of electronic optics equipment, like laser cutting machines, color sorters and so on. we use a high performance oil separator and cooling system to ensure that provide the cleanest compressed air to your equipment.
7. Longer warranty compare to other companies
Our warranty is 2 years for complete machine, compare to other companies, mostly of them are providing 1 year warranty. With 20 years experience we have confidence to make good service to our customers all over the world.
