Air-endSingle screw air-end made by Japanese technology, The interior consists of 1 horizontal screw plus up & down 2 vertically placed star wheels, it's more like "3 screws". As this symmetrical structure design makes the axial force and radial force cancel each other, improve the stability of the operation and compression efficiency, but lesser noise.No like the copper screw, our air-end is made buy stainless steel without any coating. Because copper screw has the possibility to generate verdigris which can spoiled your water and air, vanish all of your effort.2. MotorCustom made professional motor for oil-free series, motor as the driving component, it's transmission ratio, service factor and rpm, almost everything affect directly to the driven component. We use permanent magnet motor which has no coil and many unnecessary parts, reduce the failure chance, decrease motor size and weight, but gives higher transmission ration.3. Automatic Water level SwitchAccording to the internal circulating water, the switch will automatically turn-on and start replenish if needed, to ensure the lubrication and cooling effect, avoid overheating all the time without any supervision needed.4. Air Filters" Mann" Original filters, using the latest alternating closed filter chamber, combined with tandem filter alignment which increases 50% filtration area by small footprint, purify the air from the very beginning.The entire element does not contain any metal parts, you can use simply do incineration or other easy treatment. The filter housing is reusable, just clean or replace the element, it saves resources and cost.5. ValvesOriginal Japanese imported valves, the best option to prevent downtime caused by leakage, plugging etc,. Ensure quality not only by experiences, but also endorsement from well-know brands, as we know detail leads to success.6. Cooling systemReasonable cooling method, cooling method (by air/water) is optional due to customer, accurately calculate the needed cooling air/water to avoid additional energy consumption. Use copper heat ex-changer for better heat dissipation effect, help compressor performs always the best!7. Intake valveCustom made for every oil-free, like opening way, angle, diameter and other many aspects, to realize 0~100% adjustment air suction range automatically. In the meantime, the the seal ring can reduce pressure loss. It's active and long life ensure stable loading and unloading for compressor.8. Invetor With the strategic cooperation agreement between Dehaha & Delta, every each invertor we use is special made from Delta, tolerate higher temperature, take care complex inlet power and maximize the performance of the permanent magnet motor. Relying on Delta's worldwide service, a better experiment is prepared for you.9. Water/air separatorSelf-develope and designed water/air separator, adopts vortex water-air separation technology, effectively separates the moisture from the compressed air, reduces the burden for after air treatment . It's totally made by stainless steel, avoid rust, keep system clean.10. Water softenerSoftened water is the only water can be used in water lube compressor, but many impurities and micro elements are exist in our water sources, if use directly the local water, then impurities can damage air-end, tanks from inside.ModelCoolingWorking PressureAir DeliveryMotor PowerAir/Water Cooling vloumeDimensionWeight barpsigm3/mincfmkw/hpL/minmmkgDCW-10AAir cooling71001.3467.5/1021100*845*126052081161.24210145//DCW-15A71001.65711/152.5/12.51100*845*126058081161.553101451.449DCW-20A71002.58815/203.5/41520*1100*140062081162.38110145271DCW-25A71003.311618.5/2541520*1100*140072081163.1109101452.588DCW-30A71003.713122/3051520*1100*140083081163.5124101453106DCW-40AWate
