Rotary Screw Air Compressor

Oil Free Screw Blower

Adekom KGF series Oil-free Screw Blowers is developed specially for low pressure applications such as wastewater treatment, pneumatic conveying and fermentation. KGF blowers adopt interior permanent magnet motor VSD technology, ensure a continuous, flexible, highly reliable energy-efficient and 100% Class 0 certified oil-free air supply for all your low pressure applications at the lowest possible operational cost.

Energy costs can add up to 80% of the lifecycle cost of a blower. Screw blowers are a type of positive displacement blower. The internal compression process of a screw blower not only leads to supply a steady, non-pulsating air flow, minimizing vibration and maintenance and maximizing lifetime, but also results in significantly lower energy consumption as a very limited amount of energy is transferred to heat.

That is why screw blowers are an energy-efficient alternative to classic rotary lobe blower solutions. On average, you can save up to 35-40% compared to lobe or roots technology.by opting for a highly efficient screw blower. The higher the pressure required by your application, the higher the potential savings and the lower your total cost of ownership.

Typical Applications
Features
  • Certified oil-free screw compression technology ( Class 0 certified ).
  • Durably-coated rotors ensure optimal operational clearances and increased lifetime.
  • Perfectly sized rotor profile result in the lowest specific power consumption.
  • Tuned cool oil injection to bearings and gears maximizing the lifetime.
  • Motor-screw blower transmission over a heavy duty gearbox.
  • Low maintenance costs, no wearing components such as belts, pulleys,…etc.Oil Free Screw Element
  •  IPM motor constructed with neodymium iron boron permanent magnet materials can prevent demagnetized even under high operating temperature up to 180℃. Services life is up to 15 years!
  •  Halo-resistance enameled cable with remarkable insulation performance is applied to stator coil for long service life.
  •  One common shaft structure design, motor without bearing structure to guarantee 100% transmission efficiency.
  •  No more greasing and replacement of bearings at regular interval.
  •  High temperature protection via PTC/PT100 is available.
  •  Wide adjustable speed range and high precision which lead to wider range of air capacity modulation.
  •  Compact size motor saves compressor foot print.
  •  Double layer housing with oil circulation that reduces noise level and realizes low vibration and stable operation.
  •  Very high efficiency: IE4 and IP65 protection class as options.
Permanent Magnet Motor
  • Proven design integrating all required electrical components for optimum reliability ( EMC filter, Variable frequency drive, RFI filter, smart controller ).
  • Reduced installation and start-up cost thanks to complete integration.Energy Efficient Inverter
  • To ensure maximum machine safety and easy networking, the intelligent PLC system controls both the blower and the integrated frequency inverter.
  • Monitoring of all parameters to ensure maximum reliability for your blower installation.
  • User-friendly Touch Screen Panel.
  • Included warning indications, maintenance scheduling and online visualization of the machine’s condition.
