The oil-free screw compressor of COAIRE boasting highest performance

Characteristics of AF Series Products

Oil-free system of Kyungwon produces 100% oil-free air

Oil-free airend acknowledged by the world

  • Prevention ol corrosion through applicallonolstainless 2- -step rotorwith up to 60,000 hours of lifetime
  • Elliciency of compressor increased by ultra coating rotor and housing, allowing for stable operation at high temperature and pressure
  • Noise and durability improved by applicationol high-speed rotation and high-precision bull gear and timing gear
  • Excellent cooling efficiency with the installation of internal oil jacket
  • Function to produce customized products for different customer demands using diverse product groups and gear ratios

Special Ultra Coating

  • Coating material:Molybdenum disulfide (MoS2) + high temperature organic resin + Tellon(clean content) +etc···
  • At first test run direct contact space between rotors is being adjusted by itself
  • High performance at 300 degrees C
  • The tellon cover is a plastic material which is viable to leakage

After 4000 hours run energy saving is 10% more than the industry average

Deiails of AF Series Product



Stainless pipe

  • Prevention of foreign substances and corrosion through the use of stainless pipe appropriate for compressed air with high temperature and humidity
  • Lifetime expanded and oil leak minimized by using stainless pipe for oil line and application of metal sealing


Application of Stainless Pre-Cooler

  • Use of Stainless Pre-Cooler for both primary and secondary discharge parts to increase cooling efficiency and reinforce durability


Hydraulic valve

  • Stable operation with hydraulic control inhalation valve showing high reliability
  • Accurate control under no-load at low pressure


3-step condensate removal system

  • 3-step condensate removal system removes most of moisture before providing compressed air
  • Semi-permanent use with installationol2-step inhalation and 2-step discharge cyclone moisture separator
  • Flow type drain valve is installed in addition to 2-step airend for perfect prevention of moisture inflow


Oil pump

  • Integrated oil pump structure maximizes energy efficiency through high durability and efficient power transmission
  • Oilaccumulator installed to alleviate pulsation for protection of machine and prevention of oilleak


Easy maintenance selected

  • Module design offers convenient disassembly for inspection and maintenance, and convenience for maintenance was secured by metal sealing and swivel joint


AOS Breather Filter

  • Breather filter applied with air-oil separator element manufacturing technology perfectly filters oil vapour in the oil tank
  • Externalinstallation of breather pipe can be done depending on the conditions of use


Large capacity inhalation filter and oil filter

  • InhalationIilier with decontamination efficiency of 99.9% is used in a large capacity for lifetime twice as long
  • Large capacity oil filter combining differential pressure switch and bypass shows stable oil supply


Low noise and low vibration design

  • Vibration minimized as all operating parts are made with vibration resistance design
  • Fan noise minimized by installation olsplit module type silencer
  • Inhaled air volume canbe adjusted by easy detachment and attachment olsplit module


Convenient Multi Micom Controller

  • Convenient operation through key-pad arrangement considering driver's motion
  • Multilingual support (Korean, Chinese, English, Russian, Portuguese)
  • Easy control by beginners through application of pyramid control method
