Industrial Rotary Scroll Air Compressor Medical Oil Free Dental Air Compressor

Compressor sucks air through air inlet located at outer scroll.Compression chamber goes smaller with rotary movement and trapped air is compressed.Compression chamber becomes minimum volume at the center of the scroll and air is pumped out through air outlet located at the center of scroll.These, suction, compression & discharging, process is repeated continuously.
Long maintenance cycle with long life consumable parts.
Compressor head replacement at every 10,000 hours or 4 years whichever comes earlier.
Scroll oil free screw air compressor, 100% oil free for food industry, dental and medical industry.

Clean oil free compressed air
Adopt 74 degree conicity dry seamless, more reliable seamless, eliminate air leakage. Not just compression process is oil free, but also on the afterward transportation adopt stainless steel pipe, stainless steel check valve, stainless steel air receiver(for air receiver mounted), ensure the quality of compressed air.

High efficiency scroll air end
Adopt the advanced oil free scroll airend, reliable bearing and grease, make sure the reliability and long life-span of airend, high precise machine for motivated scroll, fixed scroll and housing, ensure high efficiency of airend. Reliable seamless material, ensure compression chamber and lubricated transmit 100% be separate, ensure compressed air is oil free.

High Reliability
Cooling fan adopt integrated centrifugal impeller, low noise, high cooling air pressure, high cooling air, ensure the cooling air is enough, ventilation fan adopt silence axial fan, ensure the heat inside of cabinet could be eliminated in time. Heat exchange has been increased 20%-30%, anticorrosive treatment inner structure, after strict testing, ensure the exhausting air less than environment temp.+10-15ºC, reduce the burden of downstream equipment. Adopt direct driven, not belt driven, improve transmission efficiency & reliability, reduce the maintenance cost of changing belt.
